Line printer Administration
|
|
.PP
|
|
The
|
|
.I lpc
|
|
program provides local control over line printer activity.
|
|
The major commands and their intended use will be described.
|
|
The command format and remaining commands are described in
|
|
.IR lpc (8).
|
|
.LP
|
|
\fBabort\fP and \fBstart\fP
|
|
.IP
|
|
.I Abort
|
|
terminates an active spooling daemon on the local host immediately and
|
|
then disables printing (preventing new daemons from being started by
|
|
.IR lpr ).
|
|
This is normally used to forcibly restart a hung line printer daemon
|
|
(i.e., \fIlpq\fP reports that there is a daemon present but nothing is
|
|
happening). It does not remove any jobs from the queue
|
|
(use the \fIlprm\fP command instead).
|
|
.I Start
|
|
enables printing and requests \fIlpd\fP to start printing jobs.
|
|
.LP
|
|
\fBenable\fP and \fBdisable\fP
|
|
.IP
|
|
\fIEnable\fP and \fIdisable\fP allow spooling in the local queue to be
|
|
turned on/off.
|
|
This will allow/prevent
|
|
.I lpr
|
|
from putting new jobs in the spool queue. It is frequently convenient
|
|
to turn spooling off while testing new line printer filters since the
|
|
.I root
|
|
user can still use
|
|
.I lpr
|
|
to put jobs in the queue but no one else can.
|
|
The other main use is to prevent users from putting jobs in the queue
|
|
when the printer is expected to be unavailable for a long time.
|
|
.LP
|
|
\fBrestart\fP
|
|
.IP
|
|
.I Restart
|
|
allows ordinary users to restart printer daemons when
|
|
.I lpq
|
|
reports that there is no daemon present.
|
|
.LP
|
|
\fBstop\fP
|
|
.IP
|
|
.I Stop
|
|
halts a spooling daemon after the current job completes;
|
|
this also disables printing. This is a clean way to shutdown a
|
|
printer to do maintenance, etc. Note that users can still enter jobs in a
|
|
spool queue while a printer is
|
|
.IR stopped .
|
|
.LP
|
|
\fBtopq\fP
|
|
.IP
|
|
.I Topq
|
|
places jobs at the top of a printer queue. This can be used
|
|
to reorder high priority jobs since
|
|
.I lpr
|
|
only provides first-come-first-serve ordering of jobs.
