;;; Commentary:
;; ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;
;; Introduction
;; ------------
;;
;; With `printing' you can preview or print a PostScript file. You can also
;; print a text file using PostScript, and preview or print buffers that use
;; certain special modes like mh-folder-mode, rmail-summary-mode,
;; gnus-summary-mode, etc. This package also includes a PostScript/text
;; printer database.
;;
;; There are two user interfaces:
;;
;; * Menu interface:
;; The `printing' menu replaces the usual print options in the menu bar.
;; This is the default user interface.
;;
;; * Buffer interface:
;; You can use a buffer interface instead of menus. It looks like a
;; customization buffer. Basically, it has the same options found in the
;; menu and some extra options, all this on a buffer.
;;
;; `printing' is prepared to run on GNU, Unix and NT systems.
;; On GNU or Unix system, `printing' depends on gs and gv utilities.
;; On NT system, `printing' depends on gstools (gswin32.exe and gsview32.exe).
;; To obtain ghostscript, ghostview and GSview see the URL
;; `https://www.gnu.org/software/ghostscript/ghostscript.html'.
;;
;; `printing' depends on ps-print package to generate PostScript files, to
;; spool and to despool PostScript buffer. So, `printing' provides an
;; interface to ps-print package and it also provides some extra stuff.
;;
;; `printing' was inspired by:
;;
;; print-nt.el Frederic Corne <frederic.corne@erli.fr>
;; Special printing functions for Windows NT
;;
;; mh-e-init.el Tom Vogels <tov@ece.cmu.edu>
;; PS-print for mail messages
;;
;; win32-ps-print.el Matthew O. Persico <mpersico@erols.com>
;; PostScript printing with ghostscript
;;
;; ps-print-interface.el Volker Franz <volker.franz@tuebingen.mpg.de>
;; Graphical front end for ps-print and previewing
;;
;;
;; Log Messages
;; ------------
;;
;; The buffer *Printing Command Output* is where the `printing' log messages
;; are inserted. All program called by `printing' has a log entry in the
;; buffer *Printing Command Output*. A log entry has the following form:
;;
;; PROGRAM (ARG...)
;; MESSAGE
;; Exit status: CODE
;;
;; Where
;; PROGRAM is the program activated by `printing',
;; ARG is an argument passed to PROGRAM (it can have more than one argument),
;; MESSAGE is an error message returned by PROGRAM (it can have no message, if
;; PROGRAM is successful),
;; and CODE is a numeric exit status or a signal description string.
;;
;; For example, after previewing a PostScript file, *Printing Command Output*
;; will have the following entry:
;;
;; /usr/bin/gv ("/home/user/example/file.ps")
;; Exit status: 0
;;
;; In the example above, the previewing was successful. If during previewing,
;; you quit gv execution (by typing C-g during Emacs session), the log entry
;; would be:
;;
;; /usr/bin/gv ("/home/user/example/file.ps")
;; Exit status: Quit
;;
;; So, if something goes wrong, a good place to take a look is the buffer
;; *Printing Command Output*. Don't forget to see also the buffer *Messages*,
;; it can help.
;;
;;
;; Novices (First Users)
;; ---------------------
;;
;; First of all, see printing documentation only to get an idea of what
;; `printing' is capable.
;;
;; Then try to set the variables: `pr-ps-name', `pr-ps-printer-alist',
;; `pr-txt-name', `pr-txt-printer-alist' and `pr-path-alist'. These variables
;; are the main variables for printing processing.
;;
;; Now, please, see these variables documentation deeper. You can do this by
;; typing C-h v pr-ps-name RET (for example) if you already loaded printing
;; package, or by browsing printing.el source file.
;;
;; If the documentation isn't clear or if you find a way to improve the
;; documentation, please, send an email to maintainer. All printing users
;; will thank you.
;;
;; One way to set variables is by calling `pr-customize', customize all
;; variables and save the customization by future sessions (see Options
;; section). Other way is by adding code to your init file; see below
;; for a first setting template that it should be inserted on your
;; init file:
;;
;; * Example of setting for Windows system:
;;
;; (require 'printing) ; load printing package
;; (setq pr-path-alist
;; '((windows "c:/applications/executables" PATH ghostview mpage)
;; (ghostview "c:/gs/gsview-dir")
;; (mpage "c:/mpage-dir")
;; ))
;; (setq pr-txt-name 'prt_06a)
;; (setq pr-txt-printer-alist
;; '((prt_06a "print" nil "/D:\\\\printers\\prt_06a")
;; (prt_07c nil nil "/D:\\\\printers\\prt_07c")
;; (PRN "" nil "PRN")
;; (standard "redpr.exe" nil "")
;; ))
;; (setq pr-ps-name 'lps_06b)
;; (setq pr-ps-printer-alist
;; '((lps_06a "print" nil "/D:" "\\\\printers\\lps_06a")
;; (lps_06b "print" nil nil "\\\\printers\\lps_06b")
;; (lps_07c "print" nil "" "/D:\\\\printers\\lps_07c")
;; (lps_08c nil nil nil "\\\\printers\\lps_08c")
;; (LPT1 "" nil "" "LPT1:")
;; (PRN "" nil "" "PRN")
;; (standard "redpr.exe" nil "" "")
;; ))
;; (pr-update-menus t) ; update now printer and utility menus
;;
;; * Example of setting for GNU or Unix system:
;;
;; (require 'printing) ; load printing package
;; (setq pr-path-alist
;; '((unix "." "~/bin" ghostview mpage PATH)
;; (ghostview "$HOME/bin/gsview-dir")
;; (mpage "$HOME/bin/mpage-dir")
;; ))
;; (setq pr-txt-name 'prt_06a)
;; (setq pr-txt-printer-alist
;; '((prt_06a "lpr" nil "prt_06a")
;; (prt_07c nil nil "prt_07c")
;; ))
;; (setq pr-ps-name 'lps_06b)
;; (setq pr-ps-printer-alist
;; '((lps_06b "lpr" nil "-P" "lps_06b")
;; (lps_07c "lpr" nil nil "lps_07c")
;; (lps_08c nil nil nil "lps_08c")
;; ))
;; (pr-update-menus t) ; update now printer and utility menus
;;
;;
;; NOTE 1: Don't forget to download and install ghostscript utilities (see
;; Utilities section).
;;
;; NOTE 2: The `printer-name' and `ps-printer-name' variables don't need to be
;; set, as they are implicit set by `pr-ps-printer-alist' and
;; `pr-txt-printer-alist'.
;;
;; NOTE 3: The duplex feature will only work on PostScript printers that
;; support this feature.
;; You can check if your PostScript printer supports duplex feature
;; by checking the printer manual. Or you can try these steps:
;; 1. Open a buffer (or use the *scratch* buffer).
;; 2. Type:
;; First line (on first page)
;; ^L
;; Second line (on second page)
;; 3. Print this buffer with duplex turned on.
;; If it's printed 2 (two) sheets of paper, then your PostScript
;; printer doesn't have duplex feature; otherwise, it's ok, your
;; printer does have duplex feature.
;;
;; NOTE 4: See Tips section.
;;
;;
;; Tips
;; ----
;;
;; 1. If you have a local printer, that is, a printer which is connected
;; directly to your computer, don't forget to connect the printer to your
;; computer before printing.
;;
;; 2. If you try to print a file and it seems that the file was printed, but
;; there is no paper in the printer, then try to set `pr-delete-temp-file'
;; to nil. Probably `printing' is deleting the temporary file before your
;; local system can get it to send to the printer.
;;
;; 3. Don't try to print a dynamic buffer, that is, a buffer which is
;; modifying while `printing' tries to print. Eventually you got an error
;; message. Instead, save the dynamic buffer to a file or copy it in
;; another buffer and, then, print the file or the new static buffer.
;; An example of dynamic buffer is the *Messages* buffer.
;;
;; 4. When running Emacs on Windows (with or without cygwin), check if your
;; printer is a text printer or not by typing in a DOS window:
;;
;; print /D:\\host\printer somefile.txt
;;
;; Where, `host' is the machine where the printer is directly connected,
;; `printer' is the printer name and `somefile.txt' is a text file.
;;
;; If the printer `\\host\printer' doesn't print the content of
;; `somefile.txt' or, instead, it returns the following message:
;;
;; PostScript Error Handler
;; Offending Command = CCC
;; Stack =
;;
;; Where `CCC' is whatever is at the beginning of the text to be printed.
;;
;; Therefore, the printer `\\host\printer' is not a text printer, but a
;; PostScript printer. So, please, don't include this printer in
;; `pr-txt-printer-alist' (which see).
;;
;; 5. You can use gsprint instead of ghostscript to print monochrome PostScript
;; files in Windows. The gsprint utility documentation says that it is more
;; efficient than ghostscript to print monochrome PostScript.
;;
;; To print non-monochrome PostScript file, the efficiency of ghostscript
;; is similar to gsprint.
;;
;; Also the gsprint utility comes together with gsview distribution.
;;
;; For more information about gsprint see
;; `https://www.cs.wisc.edu/~ghost/gsview/gsprint.htm'.
;;
;; As an example of gsprint declaration:
;;
;; (setq pr-ps-printer-alist
;; '((A "gsprint" ("-all" "-twoup") "-printer " "my-b/w-printer-name")
;; (B "gsprint" ("-all" "-twoup") nil "-printer my-b/w-printer-name")
;; ;; some other printer declaration
;; ))
;;
;; The example above declares that printer A prints all pages (-all) and two
;; pages per sheet (-twoup). The printer B declaration does the same as the
;; printer A declaration, the only difference is the printer name selection.
;;
;; There are other command line options like:
;;
;; -mono Render in monochrome as 1bit/pixel (only black and white).
;; -grey Render in greyscale as 8bits/pixel.
;; -color Render in color as 24bits/pixel.
;;
;; The default is `-mono'. So, printer A and B in the example above are
;; using implicitly the `-mono' option. Note that in `-mono' no gray tone
;; or color is printed, this includes the zebra stripes, that is, in `-mono'
;; the zebra stripes are not printed.
;;
;; See also documentation for `pr-ps-printer-alist'.
;;
;;
;; Using `printing'
;; ----------------
;;
;; To use `printing' insert in your init file:
;;
;; (require 'printing)
;; ;; ...some user settings...
;; (pr-update-menus t)
;;
;; During `pr-update-menus' evaluation:
;; * On Emacs 20:
;; it replaces the Tools/Print menu by Tools/Printing menu.
;; * On Emacs 21:
;; it replaces the File/Print* menu entries by File/Print menu.
;; Please, see section Menu Layout below for menu explanation.
;;
;; To use `printing' utilities you can use the Printing menu options, type M-x
;; followed by one of the commands below, or type a key associated with the
;; command you want (if there is a key binding).
;;
;; `printing' has the following commands:
;;
;; pr-interface
;; pr-ps-directory-preview
;; pr-ps-directory-using-ghostscript
;; pr-ps-directory-print
;; pr-ps-directory-ps-print
;; pr-ps-buffer-preview
;; pr-ps-buffer-using-ghostscript
;; pr-ps-buffer-print
;; pr-ps-buffer-ps-print
;; pr-ps-region-preview
;; pr-ps-region-using-ghostscript
;; pr-ps-region-print
;; pr-ps-region-ps-print

;; pr-despool-preview
;; pr-despool-using-ghostscript
;; pr-despool-print
;; pr-despool-ps-print
;; pr-printify-directory
;; pr-printify-buffer
;; pr-printify-region
;; pr-txt-directory
;; pr-txt-buffer
;; pr-txt-region
;; pr-txt-mode
;; pr-txt-fast-fire
;; pr-toggle-file-duplex
;; pr-toggle-file-tumble
;; pr-toggle-file-landscape
;; pr-toggle-ghostscript
;; pr-toggle-faces
;; pr-toggle-spool
;; pr-toggle-duplex
;; pr-toggle-tumble
;; pr-toggle-landscape
;; pr-toggle-upside-down
;; pr-toggle-line
;; pr-toggle-zebra
;; pr-toggle-header
;; pr-toggle-lock
;; pr-toggle-region
;; pr-toggle-mode
;; pr-customize
;; lpr-customize
;; pr-help
;; pr-ps-name
;; pr-txt-name
;; pr-ps-utility
;; pr-show-ps-setup
;; pr-show-pr-setup
;; pr-show-lpr-setup
;;
;; The general meanings of above commands are:
;;
;; PREFIX:
;; `pr-interface' buffer interface for printing package.
;; `pr-help' help for printing package.
;; `pr-ps-name' interactively select a PostScript printer.
;; `pr-txt-name' interactively select a text printer.
;; `pr-ps-utility' interactively select a PostScript utility.
;; `pr-show-*-setup' show current settings.
;; `pr-ps-*' deal with PostScript code generation.
;; `pr-txt-*' deal with text generation.
;; `pr-toggle-*' toggle on/off some boolean variable.
;; `pr-despool-*' despool the PostScript spooling buffer.
;; `pr-printify-*' replace nonprintable ASCII by printable ASCII
;; representation.
;;
;; SUFFIX:
;; `*-customize' customization.
;; `*-preview' preview a PostScript file.
;; `*-using-ghostscript' use ghostscript to print.
;; `*-fast-fire' fast fire command (see it for documentation).
;; `*-print' send PostScript directly to printer.
;; `*-ps-print' send PostScript directly to printer or use
;; ghostscript to print. It depends on
;; `pr-print-using-ghostscript' option.
;;
;; INFIX/SUFFIX:
;; `*-directory*' process a directory.
;; `*-buffer*' process a buffer.
;; `*-region*' process a region.
;; `*-mode*' process a major mode (see explanation below).
;; `*-file-*' process a PostScript file.
;; `*-file-up-*' process a PostScript file using a filter utility.
;;
;; Here are some examples:
;;
;; `pr-ps-buffer-using-ghostscript'
;; Use ghostscript to print a buffer.
;;
;; `pr-ps-file-print'
;; Print a PostScript file.
;;
;; `pr-toggle-spool'
;; Toggle spooling buffer.
;;
;; So you can preview through ghostview, use ghostscript to print (if you don't
;; have a PostScript printer) or send directly to printer a PostScript code
;; generated by `ps-print' package.
;;
;; Besides operating one buffer or region each time, you also can postpone
;; previewing or printing by saving the PostScript code generated in a
;; temporary Emacs buffer. This way you can save banner pages between
;; successive printing. You can toggle on/off spooling by invoking
;; `pr-toggle-spool' interactively or through menu bar.
;;
;; If you type, for example:
;;
;; C-u M-x pr-ps-buffer-print RET
;;
;; The `pr-ps-buffer-print' command prompts you for a n-up printing number and
;; a file name, and save the PostScript code generated to the file name instead
;; of sending to printer.
;;
;; This behavior is similar with the commands that deal with PostScript code
;; generation, that is, with `pr-ps-*' and `pr-despool-*' commands. If
;; spooling is on, only `pr-despool-*' commands prompt for a file name and save
;; the PostScript code spooled in this file.
;;
;; Besides the behavior described above, the `*-directory*' commands also
;; prompt for a directory and a file name regexp. So, it's possible to process
;; all or certain files on a directory at once (see also documentation for
;; `pr-list-directory').
;;
;; `printing' has also a special way to handle some major mode through
;; `*-mode*' commands. So it's possible to customize a major mode printing,
;; it's only needed to declare the customization in `pr-mode-alist' (see
;; section Options) and invoke some of `*-mode*' commands. An example for
;; major mode usage is when you're using gnus (or mh, or rmail, etc.) and
;; you're in the *Summary* buffer, if you forget to switch to the *Article*
;; buffer before printing, you'll get a nicely formatted list of article
;; subjects shows up at the printer. With major mode printing you don't need
;; to switch from gnus *Summary* buffer first.
;;
;; Current global keyboard mapping is:
;;
;; (global-set-key [print] 'pr-ps-fast-fire)
;; (global-set-key [M-print] 'pr-ps-mode-using-ghostscript)
;; (global-set-key [S-print] 'pr-ps-mode-using-ghostscript)
;; (global-set-key [C-print] 'pr-txt-fast-fire)
;; (global-set-key [C-M-print] 'pr-txt-fast-fire)
;;
;; As a suggestion of global keyboard mapping for some `printing' commands:
;;
;; (global-set-key "\C-ci" 'pr-interface)
;; (global-set-key "\C-cbp" 'pr-ps-buffer-print)
;; (global-set-key "\C-cbx" 'pr-ps-buffer-preview)
;; (global-set-key "\C-cbb" 'pr-ps-buffer-using-ghostscript)
;; (global-set-key "\C-crp" 'pr-ps-region-print)
;; (global-set-key "\C-crx" 'pr-ps-region-preview)
;; (global-set-key "\C-crr" 'pr-ps-region-using-ghostscript)

;; See `pr-visible-entry-list' for hiding some parts of the menu.
;;
;; The menu has the following sections:
;;
;; A. Interface:
;;
;; 0. You can use a buffer interface instead of menus. It looks like the
;; customization buffer. Basically, it has the same options found in the
;; menu and some extra options, all this on a buffer.
;;
;; I. PostScript printing:
;;
;; 1. You can generate a PostScript file (if you type C-u before activating
;; menu) or PostScript temporary file for a directory, a buffer, a region
;; or a major mode, choosing 1-up, 2-up, 4-up or any other n-up printing;
;; after file generation, ghostview is activated using the file generated
;; as argument. This option is disabled if spooling is on (option 16).
;; Also, if you already have a PostScript file you can preview it.
;; Instead of previewing each buffer, region or major mode at once, you
;; can save temporarily the PostScript code generated in a buffer and
;; preview it later. The option `Despool...' despools the PostScript
;; spooling buffer in a temporary file and uses ghostview to preview it.
;; If you type C-u before choosing this option, the PostScript code
;; generated is saved in a file instead of saving in a temporary file.
;; To spool the PostScript code generated you need to turn on the option
;; 16. The option `Despool...' is enabled if spooling is on (option
;; 16).
;;
;; NOTE 1: It's possible to customize a major mode printing, just declare
;; the customization in `pr-mode-alist' and invoke some of
;; `*-mode*' commands or select Mode option in Printing menu. An
;; example for major mode usage is when you're using gnus (or mh,
;; or rmail, etc.) and you're in the *Summary* buffer, if you
;; forget to switch to the *Article* buffer before printing,
;; you'll get a nicely formatted list of article subjects shows
;; up at the printer. With major mode printing you don't need to
;; switch from gnus *Summary* buffer first.
;;
;; NOTE 2: There are the following options for PostScript file
;; processing:
;; Ia. Print the file *No Preprocessing*, that is, send it
;; directly to PostScript printer.
;; Ib. PostScript utility processing selection.
;; See `pr-ps-utility-alist' and `pr-setting-database' for
;; documentation.
;; Ic. Do n-up processing before printing.
;; Id. Toggle on/off landscape for PostScript file processing.
;; Ie. Toggle on/off duplex for PostScript file processing.
;; If. Toggle on/off tumble for PostScript file processing.
;;
;; NOTE 3: Don't forget to download and install the utilities declared on
;; `pr-ps-utility-alist'.
;;
;; 2. Operate the same way as option 1, but it sends directly the PostScript
;; code (or put in a file, if you've typed C-u) or it uses ghostscript to
;; print the PostScript file generated. It depends on option 18, if it's
;; turned on, it uses ghostscript; otherwise, it sends directly to
;; printer. If spooling is on (option 16), the PostScript code is saved
;; temporarily in a buffer instead of printing it or saving it in a file.
;; Also, if you already have a PostScript file you can print it. Instead
;; of printing each buffer, region or major mode at once, you can save
;; temporarily the PostScript code generated in a buffer and print it
;; later. The option `Despool...' despools the PostScript spooling
;; buffer directly on a printer. If you type C-u before choosing this
;; option, the PostScript code generated is saved in a file instead of
;; sending to printer. To spool the PostScript code generated you need
;; to turn on the option 16. This option is enabled if spooling is on
;; (option 16). See also the NOTE 1, NOTE 2 and NOTE 3 on option 1.
;;
;; 3. You can select a new PostScript printer to send PostScript code
;; generated. For selection it's used all PostScript printers defined
;; in `pr-ps-printer-alist' variable (see it for documentation).
;; See also `pr-setting-database'.
;;
;; II. Text printing:
;;
;; 4. If you have control characters (character code from \000 to \037) in a
;; buffer and you want to print them in a text printer, select this
;; option. All control characters in your buffer or region will be
;; replaced by a printable representation. The printable representations
;; use ^ (for ASCII control characters) or hex. The characters tab,
;; linefeed, space, return and formfeed are not affected. You don't need
;; to select this option if you use any option of section I, the
;; PostScript engine treats control characters properly.
;;
;; 5. If you want to print a directory, buffer, region or major mode in a
;; text printer, select this option. See also the NOTE 1 on option 1.
;;
;; 6. You can select a new text printer to send text generated. For
;; selection it's used all text printers defined in
;; `pr-txt-printer-alist' variable (see it for documentation).
;; See also `pr-setting-database'.
;;
;; III. PostScript page toggle options:
;;
;; 7. If you want a PostScript landscape printing, turn on this option.
;;
;; 8. If you want to have a header in each page in your PostScript code,
;; turn on this option.
;;
;; 9. If you want to draw a gaudy frame around the header, turn on this
;; option. This option is enabled if print header is on (option 8).
;;
;; 10. If you want that the line number is printed in your PostScript code,
;; turn on this option.
;;
;; 11. If you want background zebra stripes in your PostScript code, turn on
;; this option.
;;
;; 12. If you want a duplex printing and your PostScript printer has this
;; feature, turn on this option.
;;
;; 13. If you turned on duplex printing, you can choose if you want to have
;; a printing suitable for binding on the left or right (tumble off), or
;; to have a printing suitable for binding at top or bottom (tumble on).
;; This option is enabled if duplex is on (option 12).
;;
;; 14. If you want a PostScript upside-down printing, turn on this option.
;;
;; 15. With this option, you can choose if you want to print all pages, odd
;; pages, even pages, odd sheets or even sheets.
;; See also `ps-even-or-odd-pages'.
;;
;; IV. PostScript processing toggle options:
;;
;; 16. If you want to spool the PostScript code generated, turn on this
;; option. To spool the PostScript code generated use option 2. You
;; can despool later by choosing option 1 or 2, sub-option `Despool...'.
;;
;; 17. If you use colors in your buffers and want to see these colors on
;; your PostScript code generated, turn on this option. If you have a
;; black/white PostScript printer, these colors are displayed in gray
;; scale by PostScript printer interpreter.
;;
;; 18. If you don't have a PostScript printer to send PostScript files, turn
;; on this option. When this option is on, the ghostscript is used to
;; print PostScript files. In GNU or Unix system, if ghostscript is set
;; as a PostScript filter, you don't need to turn on this option.
;;
;; V. Printing customization:
;;
;; 19. If you want that region is automagically detected, turn on this
;; option. Note that this will only work if you're using transient mark
;; mode. When this option is on, the `*-buffer*' commands will behave
;; like `*-region*' commands, that is, `*-buffer*' commands will print
;; only the region marked instead of all buffer.
;;
;; 20. Turn this option on if you want that when current major-mode is
;; declared in `pr-mode-alist', the `*-buffer*' and `*-region*' commands
;; behave like `*-mode*' commands.
;;
;; 21. If you want that Printing menu stays open while you are setting
;; toggle options, turn on this option. The variables
;; `pr-menu-char-height' and `pr-menu-char-width' are used to guess the
;; menu position, so don't forget to adjust these variables if menu
;; position is not ok.
;;
;; VI. Customization:
;;
;; 22. Besides all options in section III, IV and V, you can customize much
;; more PostScript options in `ps-print' option. Or you can customize
;; some `lpr' options for text printing. Or customize `printing'
;; options.
;;
;; 23. Show current settings for `printing', `ps-print' or `lpr'.
;;
;; 24. Quick help for printing menu layout.

Where:
ENTRY It's a symbol, used to identify this entry.
There must exist at least one of the following entries:
`unix' this entry is used when Emacs is running on GNU or
Unix system.
`cygwin' this entry is used when Emacs is running on Windows
98/NT/2000 with Cygwin.
`windows' this entry is used when Emacs is running on Windows
98/NT/2000.
DIRECTORY It should be a string or a symbol. If it's a symbol, it should
exist an equal entry in `pr-path-alist'. If it's a string,
it's considered a directory specification.
The directory specification may contain:
$var environment variable expansion
~/ tilde expansion
./ current directory
../ previous directory
For example, let's say the home directory is /home/my and the
current directory is /home/my/dir, so:
THE ENTRY IS EXPANDED TO
~/entry /home/my/entry
./entry /home/my/dir/entry
../entry /home/my/entry
$HOME/entry /home/my/entry
$HOME/~/other/../my/entry /home/my/entry
SPECIAL SYMBOL: If the symbol `PATH' is used in the directory
list and there isn't a `PATH' entry in `pr-path-alist' or the
`PATH' entry has a null directory list, the PATH environment
variable is used.

SYMBOL It's a symbol to identify a text printer. It's for

COMMAND Name of the program for printing a text file. On MS-DOS and
MS-Windows systems, if the value is an empty string, then Emacs
will write directly to the printer port given by NAME (see text
below), that is, the NAME should be something like \"PRN\" or
\"LPT1:\".
If NAME is something like \"\\\\\\\\host\\\\share-name\" then
COMMAND shouldn't be an empty string.
The programs `print' and `nprint' (the standard print programs
on Windows NT and Novell Netware respectively) are handled
specially, using NAME as the destination for output; any other
program is treated like `lpr' except that an explicit filename
is given as the last argument.
If COMMAND is nil, it's used the default printing program:
`print' for Windows system, `lp' for lp system and `lpr' for
all other systems. See also `pr-path-alist'.
Examples:
\"print\"
\"lpr\"

SWITCHES List of sexp's to pass as extra options for text printer
program. It is recommended to set NAME (see text below)
instead of including an explicit switch on this list.
Example:
. for lpr
(\"-#3\" \"-l\")
nil
NAME A string that specifies a text printer name.
On Unix-like systems, a string value should be a name
understood by lpr's -P option (or lp's -d option).
On MS-DOS and MS-Windows systems, it is the name of a printer
device or port. Typical non-default settings would be \"LPT1:\"
to \"LPT3:\" for parallel printers, or \"COM1\" to \"COM4\" or
\"AUX\" for serial printers, or \"\\\\\\\\hostname\\\\printer\"
(or \"/D:\\\\\\\\hostname\\\\printer\") for a shared network
printer. You can also set it to a name of a file, in which
case the output gets appended to that file. If you want to
discard the printed output, set this to \"NUL\".
Examples:
. for print.exe
\"/D:\\\\\\\\host\\\\share-name\"

PRINTER-SWITCH A string that specifies PostScript printer name switch. If
it's necessary to have a space between PRINTER-SWITCH and NAME,
it should be inserted at the end of PRINTER-SWITCH string.
If PRINTER-SWITCH is nil, it's used the default printer name
switch: `/D:' for Windows system, `-d' for lp system and `-P'
for all other systems.
Examples:
. for lpr
\"-P \"
. for lp
\"-d \"
. for print.exe
\"/D:\"
. for gsprint.exe

NAME A string that specifies a PostScript printer name.
On Unix-like systems, a string value should be a name

On MS-DOS and MS-Windows systems, it is the name of a printer
device or port. Typical non-default settings would be \"LPT1:\"

\"/D:\\\\\\\\host\\\\share-name\"
\"\\\\\\\\host\\\\share-name\"
\"LPT1:\"
\"PRN\"
. for lpr or lp
\"share-name\"
DEFAULT It's a way to set default values when this entry is selected.
It's a cons like:
(VARIABLE . VALUE)
Which associates VARIABLE with VALUE. When this entry is
selected, it's executed the following command:
(set VARIABLE (eval VALUE))
Note that VALUE can be any valid Lisp expression. So, don't
forget to quote symbols and constant lists.
If VARIABLE is the special keyword `inherits-from:', VALUE must
be a symbol name setting defined in `pr-setting-database' from
which the current setting inherits the context. Take care with
circular inheritance.
Examples:
(ps-landscape-mode . nil)
(ps-spool-duplex . t)
(pr-gs-device . (my-gs-device t))
This variable should be modified by customization engine. If this variable is
modified by other means (for example, a Lisp function), use `pr-update-menus'
function (see it for documentation) to update PostScript printer menu.
Examples:
* On GNU or Unix system:
((lps_06b \"lpr\" nil \"-P\" \"lps_06b\")
(lps_07c \"lpr\" nil nil \"lps_07c\")
(lps_08c nil nil nil \"lps_08c\")
)
* On Windows system:
((lps_06a \"print\" nil \"/D:\" \"\\\\\\\\printers\\\\lps_06a\")
(lps_06b \"print\" nil nil \"\\\\\\\\printers\\\\lps_06b\")
(lps_07c \"print\" nil \"\" \"/D:\\\\\\\\printers\\\\lps_07c\")
(lps_08c nil nil nil \"\\\\\\\\printers\\\\lps_08c\")
(b/w1 \"gsprint\" (\"-all\" \"-twoup\") \"-printer \" \"b/w-pr-name\")
(b/w2 \"gsprint\" (\"-all\" \"-twoup\") nil \"-printer \\\\\\\\printers\\\\lps_06a\")
(LPT1 \"\" nil \"\" \"LPT1:\")
(PRN \"\" nil \"\" \"PRN\")
(standard \"redpr.exe\" nil \"\" \"\")
)
gsprint:
You can use gsprint instead of ghostscript to print monochrome PostScript files
in Windows. The gsprint utility documentation says that it is more efficient
than ghostscript to print monochrome PostScript.
To print non-monochrome PostScript file, the efficiency of ghostscript is
similar to gsprint.
Also the gsprint utility comes together with gsview distribution.
As an example of gsprint declaration:
(setq pr-ps-printer-alist
\\='((A \"gsprint\" (\"-all\" \"-twoup\") \"-printer \" \"lps_015\")
(B \"gsprint\" (\"-all\" \"-twoup\") nil \"-printer lps_015\")
;; some other printer declaration
))
The example above declares that printer A prints all pages (-all) and two pages
per sheet (-twoup). The printer B declaration does the same as the printer A
declaration, the only difference is the printer name selection.
There are other command line options like:
-mono Render in monochrome as 1bit/pixel (only black and white).
-grey Render in greyscale as 8bits/pixel.
-color Render in color as 24bits/pixel.
The default is `-mono'. So, printer A and B in the example above are using
implicitly the `-mono' option. Note that in `-mono' no gray tone or color is
printed, this includes the zebra stripes, that is, in `-mono' the zebra stripes
are not printed.

"Specify an alist for a major-mode and printing functions.
To customize a major mode printing, just declare the customization in
`pr-mode-alist' and invoke some of `*-mode*' commands. An example for major
mode usage is when you're using gnus (or mh, or rmail, etc.) and you're in the
*Summary* buffer, if you forget to switch to the *Article* buffer before
printing, you'll get a nicely formatted list of article subjects shows up at
the printer. With major mode printing you don't need to switch from gnus
*Summary* buffer first.
The elements have the following form:
(MAJOR-MODE
LPR-PRINT PS-PRINT
HEADER-LINES
LEFT-HEADER
RIGHT-HEADER
KILL-LOCAL-VARIABLE
DEFAULT...)
Where:
MAJOR-MODE It's the major mode symbol.
LPR-PRINT It's a symbol function for text printing. It's invoked with
one argument:
(HEADER-LINES LEFT-HEADER RIGHT-HEADER DEFAULT...).
Usually LPR-PRINT function prepares the environment or buffer
and then call the function `pr-mode-lpr' which it's used to
process the buffer and send it to text printer.
The `pr-mode-lpr' definition is:
(pr-mode-lpr HEADER-LIST &optional FROM TO)
Where HEADER-LIST is like the argument passed to LPR-PRINT.
FROM and TO are the beginning and end markers, respectively,
for a region. If FROM is nil, it's used (point-min); if TO is
nil, it's used (point-max).
PS-PRINT It's a symbol function for PostScript printing. It's invoked
with three arguments: n-up printing, file name and the list:
(HEADER-LINES LEFT-HEADER RIGHT-HEADER DEFAULT...).
Usually PS-PRINT function prepares the environment or buffer
and then call the function `pr-mode-print' which it's used to
process the buffer and send it to PostScript printer.
The `pr-mode-print' definition is:
(pr-mode-print N-UP FILENAME HEADER-LIST &optional FROM TO)
Where N-UP, FILENAME and HEADER-LIST are like the arguments
passed to PS-PRINT. FROM and TO are the beginning and end
markers, respectively, for a region. If TO is nil, it's used
(point-max).
HEADER-LINES It's the number of header lines; if is nil, it uses
`ps-header-lines' value.
LEFT-HEADER It's the left header part, it's a list of string, variable
symbol or function symbol (with no argument); if is nil, it
uses `ps-left-header' value.
RIGHT-HEADER It's the right header part, it's a list of string, variable
symbol or function symbol (with no argument); if is nil, it
uses `ps-right-header' value.
KILL-LOCAL-VARIABLE
Non-nil means to kill all buffer local variable declared in
DEFAULT (see below).
DEFAULT It's a way to set default values when this entry is selected.
It's a cons like:
(VARIABLE-SYM . VALUE)
Which associates VARIABLE-SYM with VALUE. When this entry is
selected, it's executed the following command:
(set (make-local-variable VARIABLE-SYM) (eval VALUE))
Note that VALUE can be any valid Lisp expression. So, don't
forget to quote symbols and constant lists.
If VARIABLE is the special keyword `inherits-from:', VALUE must
be a symbol name setting defined in `pr-setting-database' from
which the current setting inherits the context. Take care with
circular inheritance.

"Specify an alist for settings in general.
The elements have the following form:
(SYMBOL INHERITS LOCAL KILL-LOCAL SETTING...)
Where:
SYMBOL It's a symbol to identify the setting group.
INHERITS Specify the inheritance for SYMBOL group. It's a symbol name
setting from which the current setting inherits the context.
If INHERITS is nil, means that there is no inheritance.
This is a simple inheritance mechanism.
Let's see an example to illustrate the inheritance mechanism:
(setq pr-setting-database
\\='((no-duplex ; setting symbol name
nil ; inherits
nil nil ; local kill-local
(pr-file-duplex . nil) ; settings
(pr-file-tumble . nil)
)
(no-duplex-and-landscape ; setting symbol name
no-duplex ; inherits
nil nil ; local kill-local
(pr-file-landscape . nil) ; settings
)))
The example above has two setting groups: no-duplex and
no-duplex-and-landscape. When setting no-duplex is activated
through `inherits-from:' (see option `pr-ps-utility',
`pr-mode-alist' and `pr-ps-printer-alist'), the variables
pr-file-duplex and pr-file-tumble are both set to nil.
Now when setting no-duplex-and-landscape is activated through
`inherits-from:', the variable pr-file-landscape is set to nil
and also the settings for no-duplex are done, because
no-duplex-and-landscape inherits settings from no-duplex.
Take care with circular inheritance. It's an error if circular
inheritance happens.
LOCAL Non-nil means that all settings for SYMBOL group will be
declared local buffer.
KILL-LOCAL Non-nil means that all settings for SYMBOL group will be
killed at end. It has effect only when LOCAL is non-nil.
SETTING It's a cons like:
(VARIABLE . VALUE)
Which associates VARIABLE with VALUE. When this entry is
selected, it's executed the following command:
* If LOCAL is non-nil:
(set (make-local-variable VARIABLE) (eval VALUE))
* If LOCAL is nil:
(set VARIABLE (eval VALUE))
Note that VALUE can be any valid Lisp expression. So, don't
forget to quote symbols and constant lists.
This setting is ignored if VARIABLE is equal to keyword
`inherits-from:'.

See `pr-visible-entry-list' for hiding some parts of the menu.
The menu has the following sections:
A. Interface:
0. You can use a buffer interface instead of menus. It looks like the
customization buffer. Basically, it has the same options found in the
menu and some extra options, all this on a buffer.
I. PostScript printing:
1. You can generate a PostScript file (if you type \\[universal-argument] before activating
menu) or PostScript temporary file for a directory, a buffer, a region
or a major mode, choosing 1-up, 2-up, 4-up or any other n-up printing;
after file generation, ghostview is activated using the file generated
as argument. This option is disabled if spooling is on (option 16).
Also, if you already have a PostScript file you can preview it.
Instead of previewing each buffer, region or major mode at once, you
can save temporarily the PostScript code generated in a buffer and
preview it later. The option `Despool...' despools the PostScript
spooling buffer in a temporary file and uses ghostview to preview it.
If you type C-u before choosing this option, the PostScript code
generated is saved in a file instead of saving in a temporary file. To
spool the PostScript code generated you need to turn on the option 16.
The option `Despool...' is enabled if spooling is on (option 16).
NOTE 1: It's possible to customize a major mode printing, just declare
the customization in `pr-mode-alist' and invoke some of
`*-mode*' commands or select Mode option in Printing menu. An
example for major mode usage is when you're using gnus (or mh,
or rmail, etc.) and you're in the *Summary* buffer, if you
forget to switch to the *Article* buffer before printing,
you'll get a nicely formatted list of article subjects shows
up at the printer. With major mode printing you don't need to
switch from gnus *Summary* buffer first.
NOTE 2: There are the following options for PostScript file processing:
Ia. Print the file *No Preprocessing*, that is, send it
directly to PostScript printer.
Ib. PostScript utility processing selection.
See `pr-ps-utility-alist' and `pr-setting-database' for
documentation.
Ic. Do n-up processing before printing.
Id. Toggle on/off landscape for PostScript file processing.
Ie. Toggle on/off duplex for PostScript file processing.
If. Toggle on/off tumble for PostScript file processing.
NOTE 3: Don't forget to download and install the utilities declared on
`pr-ps-utility-alist'.
2. Operate the same way as option 1, but it sends directly the PostScript
code (or put in a file, if you've typed \\[universal-argument]) or it uses ghostscript to
print the PostScript file generated. It depends on option 18, if it's
turned on, it uses ghostscript; otherwise, it sends directly to
printer. If spooling is on (option 16), the PostScript code is saved
temporarily in a buffer instead of printing it or saving it in a file.
Also, if you already have a PostScript file you can print it.
Instead of printing each buffer, region or major mode at once, you can
save temporarily the PostScript code generated in a buffer and print it
later. The option `Despool...' despools the PostScript spooling buffer
directly on a printer. If you type \\[universal-argument] before choosing this option,
the PostScript code generated is saved in a file instead of sending it to
the printer. To spool the PostScript code generated you need to turn on
option 16. This option is enabled if spooling is on (option 16).
See also the NOTE 1, NOTE 2 and NOTE 3 on option 1.
3. You can select a new PostScript printer to send PostScript code
generated. For selection it's used all PostScript printers defined
in `pr-ps-printer-alist' variable (see it for documentation).
See also `pr-setting-database'.
II. Text printing:
4. If you have control characters (character code from \\000 to \\037) in a
buffer and you want to print them in a text printer, select this
option. All control characters in your buffer or region will be
replaced by a printable representation. The printable representations
use ^ (for ASCII control characters) or hex. The characters tab,
linefeed, space, return and formfeed are not affected.
You don't need to select this option if you use any option of section
I, the PostScript engine treats control characters properly.
5. If you want to print a directory, buffer, region or major mode in a
text printer, select this option. See also the NOTE 1 on option 1.
6. You can select a new text printer to send text generated. For
selection it's used all text printers defined in `pr-txt-printer-alist'
variable (see it for documentation).
See also `pr-setting-database'.
III. PostScript page toggle options:
7. If you want a PostScript landscape printing, turn on this option.
8. If you want to have a header in each page in your PostScript code,
turn on this option.
9. If you want to draw a gaudy frame around the header, turn on this
option. This option is enabled if print header is on (option 8).
10. If you want that the line number is printed in your PostScript code,
turn on this option.
11. If you want background zebra stripes in your PostScript code, turn on
this option.
12. If you want a duplex printing and your PostScript printer has this
feature, turn on this option.
13. If you turned on duplex printing, you can choose if you want to have a
printing suitable for binding on the left or right (tumble off), or to
have a printing suitable for binding at top or bottom (tumble on).
This option is enabled if duplex is on (option 12).
14. If you want a PostScript upside-down printing, turn on this option.
15. With this option, you can choose if you want to print all pages, odd
pages, even pages, odd sheets or even sheets.
See also `ps-even-or-odd-pages'.
IV. PostScript processing toggle options:
16. If you want to spool the PostScript code generated, turn on this
option. To spool the PostScript code generated use option 2. You can
despool later by choosing option 1 or 2, sub-option `Despool...'.
17. If you use colors in your buffers and want to see these colors on your
PostScript code generated, turn on this option. If you have a
black/white PostScript printer, these colors are displayed in gray
scale by PostScript printer interpreter.
18. If you don't have a PostScript printer to send PostScript files, turn
on this option. When this option is on, the ghostscript is used to
print PostScript files. In GNU or Unix system, if ghostscript is set
as a PostScript filter, you don't need to turn on this option.
V. Printing customization:
19. If you want that region is automagically detected, turn on this
option. Note that this will only work if you're using transient mark
mode. When this option is on, the `*-buffer*' commands will behave
like `*-region*' commands, that is, `*-buffer*' commands will print
only the region marked instead of all buffer.
20. Turn this option on if you want that when current major-mode is
declared in `pr-mode-alist', the `*-buffer*' and `*-region*' commands
behave like `*-mode*' commands.
21. If you want that Printing menu stays open while you are setting
toggle options, turn on this option. The variables
`pr-menu-char-height' and `pr-menu-char-width' are used to guess the
menu position, so don't forget to adjust these variables if menu
position is not ok.
VI. Customization:
22. Besides all options in section III, IV and V, you can customize much
more PostScript options in `ps-print' option. Or you can customize
some `lpr' options for text printing. Or customize `printing'
options.
23. Show current settings for `printing', `ps-print' or `lpr'.
24. Quick help for printing menu layout.

(defconst pr-interface-help-message
"\
The printing interface buffer has the same functionality as the printing menu.
The major difference is that the states (like sending PostScript generated to a
file, n-up printing, etc.) are set and saved between printing buffer
activation. Also, the landscape, duplex and tumble values are the same for
PostScript file and directory/buffer/region/mode processing; using menu, there
are different value sets for PostScript file and directory/buffer/region/mode
processing.
The printing interface buffer has the following sections:
1. Print:
Here you can choose to print/preview a buffer, a directory or a PostScript
file:
1a. Buffer:
* Buffer List:
Select a buffer from the current buffer list.
* Region:
If it's on, this means that the selected buffer has an active region,
so you can turn on/off, as you wish.
If it's off when a buffer is selected, this means that the selected
buffer has no active region, so it'll not be possible to turn it on.
If you want to process the region, let this option on.
If you want to process the whole buffer, let this option off.
* Mode:
If it's on, this means that the selected buffer major mode is declared
for major mode processing, so you can turn on/off, as you wish.
If it's off when a buffer is selected, this means that the selected
buffer major mode isn't declared for major mode processing, so it'll
not be possible to turn it on.
If you want the major mode processing, let this option on.
If you don't want the major mode processing, let this option off.
NOTE 1: It's possible to customize a major mode printing, just declare
the customization in `pr-mode-alist' and invoke some of
`*-mode*' commands or select Mode option in Printing menu. An
example for major mode usage is when you're using gnus (or mh,
or rmail, etc.) and you're in the *Summary* buffer, if you
forget to switch to the *Article* buffer before printing,
you'll get a nicely formatted list of article subjects shows
up at the printer. With major mode printing you don't need to
switch from gnus *Summary* buffer first.
1b. Directory:
* Directory:
Specify a valid directory path.
* File Regexp:
Specify a file name regexp. All file names in the directory that
match with regexp will be printed/previewed. An empty file name
regexp means to print/preview all files in the directory.
* List Directory Entry:
If it's turned on, list directory entries besides file entries.
1c. PostScript file:
* PostScript File:
Specify an existent PostScript file to print/preview.
* PostScript Utility:
Select a PostScript utility.
See `pr-ps-utility-alist' and `pr-setting-database' for documentation.
NOTE 2: Don't forget to download and install the utilities declared on
`pr-ps-utility-alist'.
* No Preprocessing:
If it's turned on, don't use the PostScript utility to preprocess the
PostScript file before printing/previewing.
2. PostScript printer:
* PostScript Printer:
You can select a new PostScript printer to send PostScript code
generated. For selection it's used all PostScript printers defined
in `pr-ps-printer-alist' variable (see it for documentation).
See also `pr-setting-database'.
* Despool:
If spooling is on, you can turn it on/off, as you wish.
If spooling is off, it'll not be possible to turn it on.
If it's turned on, specify to despools the PostScript spooling buffer in
a temporary file or in the selected PostScript file when
printing/previewing.
* Preview:
Preview the PostScript generated.
* Print:
Print the PostScript generated.
* Quit:
Quit from printing interface buffer.
* Send to Printer/Temporary File:
If it's turned on, the PostScript generated is sent directly to
PostScript printer or, for previewing, to a temporary file.
* Send to File:
Specify a file name to send the PostScript generated.
* N-Up:
Specify n-up printing.
3. Text printer:
* Text Printer:
Select a new text printer to send text generated. For selection it's used
all text printers defined in `pr-txt-printer-alist' variable (see it for
documentation). See also `pr-setting-database'.
* Printify:
If you have control characters (character code from \\000 to \\037) in a
buffer and you want to print them in a text printer, select this
option. All control characters in your buffer or region will be
replaced by a printable representation. The printable representations
use ^ (for ASCII control characters) or hex. The characters tab,
linefeed, space, return and formfeed are not affected.
You don't need to select this option if you use any option of section
I, the PostScript engine treats control characters properly.
* Print:
To print a directory, buffer, region or major mode in a
text printer, select this option. See also the NOTE 1 on section 1.
* Quit:
Quit from printing interface buffer.
4. Settings:
There are 3 setting columns:
4a. First column (left column):
* Landscape:
PostScript landscape printing.
* Print Header:
To have a header in each page in your PostScript code.
* Print Header Frame:
To draw a gaudy frame around the header.
* Line Number:
The line number is printed in your PostScript code.
* Zebra Stripes:
Background zebra stripes in your PostScript code.
* Duplex:
Duplex printing (if your PostScript printer has this feature).
* Tumble:
If duplex printing is on, you can choose if you want to have a
printing suitable for binding on the left or right (tumble off), or to
have a printing suitable for binding at top or bottom (tumble on).
* Upside-Down:
PostScript upside-down printing.
4b. Second column (middle column):
* Auto Region:
If you want that region is automagically detected, turn on this
option. Note that this will only work if you're using transient mark
mode. When this option is on, the `*-buffer*' commands will behave
like `*-region*' commands, that is, `*-buffer*' commands will print
only the region marked instead of all buffer.
* Auto Mode:
Turn this option on if you want that when current major-mode is
declared in `pr-mode-alist', the `*-buffer*' and `*-region*' commands
behave like `*-mode*' commands.
* Menu Lock:
If you want that Printing menu stays open while you are setting
toggle options, turn on this option. The variables
`pr-menu-char-height' and `pr-menu-char-width' are used to guess the
menu position, so don't forget to adjust these variables if menu
position is not ok.
* Spool Buffer:
To spool the PostScript code generated. You can despool later by
setting Despool option on PostScript printer section.
* Print with faces:
If you use colors in your buffers and want to see these colors on your
PostScript code generated, turn on this option. If you have a
black/white PostScript printer, these colors are displayed in gray
scale by PostScript printer interpreter.
* Print via Ghostscript:
If you don't have a PostScript printer to send PostScript files, turn
on this option. When this option is on, the ghostscript is used to
print PostScript files. In GNU or Unix system, if ghostscript is set
as a PostScript filter, you don't need to turn on this option.
* Parity Page Menu:
To print all pages, odd pages, even pages, odd sheets or even sheets.
See also `ps-even-or-odd-pages'.
4c. Third column (right column):
* Verbose:
That is, to be verbose when editing a field in interface buffer.
5. Customize:
Besides all options in section 4, you can customize much more PostScript
options in `ps-print' option. Or you can customize some `lpr' options for
text printing. Or customize `printing' options.
6. Show settings:
Show current settings for `printing', `ps-print' or `lpr'.
7. Help:
Quick help for printing interface buffer and printing menu layout. You can
also quit the printing interface buffer or kill all printing help buffer.

"Fast fire function for PostScript printing.
If a region is active, the region will be printed instead of the whole buffer.
Also if the current major-mode is defined in `pr-mode-alist', the settings in
`pr-mode-alist' will be used, that is, the current buffer or region will be
printed using `pr-ps-mode-ps-print'.
Interactively, you have the following situations:
\\[pr-ps-fast-fire]
The command prompts the user for a N-UP value and printing will
immediately be done using the current active printer.
\\[universal-argument] \\[pr-ps-fast-fire]
\\[universal-argument] 0 \\[pr-ps-fast-fire]
The command prompts the user for a N-UP value and also for a current
PostScript printer, then printing will immediately be done using the new
current active printer.
\\[universal-argument] 1 \\[pr-ps-fast-fire]
The command prompts the user for a N-UP value and also for a file name,
and saves the PostScript image in that file instead of sending it to the
printer.
\\[universal-argument] 2 \\[pr-ps-fast-fire]
The command prompts the user for a N-UP value, then for a current
PostScript printer and, finally, for a file name. Then change the active
printer to that chosen by user and saves the PostScript image in
that file instead of sending it to the printer.
Noninteractively, the argument N-UP should be a positive integer greater than
zero and the argument SELECT is treated as follows:
If it's nil, send the image to the printer.
If it's a list or an integer lesser or equal to zero, the command prompts
the user for a current PostScript printer, then printing will immediately
be done using the new current active printer.
If it's an integer equal to 1, the command prompts the user for a file name
and saves the PostScript image in that file instead of sending it to the
printer.
If it's an integer greater or equal to 2, the command prompts the user for a
current PostScript printer and for a file name. Then change the active
printer to that chosen by user and saves the PostScript image in that file
instead of sending it to the printer.
If it's a symbol which it's defined in `pr-ps-printer-alist', it's the new
active printer and printing will immediately be done using the new active
printer.
Otherwise, send the image to the printer.
Note that this command always behaves as if `pr-auto-region' and `pr-auto-mode'
are both set to t."

If a region is active, the region will be printed instead of the whole buffer.
Also if the current major-mode is defined in `pr-mode-alist', the settings in
`pr-mode-alist' will be used, that is, the current buffer or region will be
printed using `pr-txt-mode'.
Interactively, when you use a prefix argument (\\[universal-argument]), the command prompts the
user for a new active text printer.
Noninteractively, the argument SELECT-PRINTER is treated as follows:
If it's nil, the printing is sent to the current active text printer.
If it's a symbol which it's defined in `pr-txt-printer-alist', it's the new
active printer and printing will immediately be done using the new active
printer.
If it's non-nil, the command prompts the user for a new active text printer.
Note that this command always behaves as if `pr-auto-region' and `pr-auto-mode'
are both set to t."
