CUPS provides a portable printing layer for UNIX-based operating
|
||
|
|
systems. It has been developed by Easy Software Products to promote a
|
||
|
|
standard printing solution for all UNIX vendors and users. CUPS
|
||
|
|
provides the System V and Berkeley command-line interfaces.
|
||
|
|
|
||
|
|
CUPS uses the Internet Printing Protocol ("IPP") as the basis for
|
||
|
|
managing print jobs and queues. The Line Printer Daemon ("LPD") Server
|
||
|
|
Message Block ("SMB"), and AppSocket (a.k.a. JetDirect) protocols are
|
||
|
|
also supported with reduced functionality. CUPS adds network printer
|
||
|
|
browsing and PostScript Printer Description ("PPD") based printing
|
||
|
|
options to support real-world printing under UNIX.
|
||
|
|
|
||
|
|
CUPS also includes a customized version of GNU Ghostscript (currently
|
||
|
|
based off GNU Ghostscript 5.50) and an image file RIP that are used to
|
||
|
|
support non-PostScript printers. Sample drivers for HP and EPSON
|
||
|
|
printers are included that use these filters.
