32 Line printer Administration
36 program provides local control over line printer activity.
37 The major commands and their intended use will be described.
38 The command format and remaining commands are described in
41 \fBabort\fP and \fBstart\fP
44 terminates an active spooling daemon on the local host immediately and
45 then disables printing (preventing new daemons from being started by
47 This is normally used to forcibly restart a hung line printer daemon
48 (i.e., \fIlpq\fP reports that there is a daemon present but nothing is
49 happening). It does not remove any jobs from the queue
50 (use the \fIlprm\fP command instead).
52 enables printing and requests \fIlpd\fP to start printing jobs.
54 \fBenable\fP and \fBdisable\fP
56 \fIEnable\fP and \fIdisable\fP allow spooling in the local queue to be
58 This will allow/prevent
60 from putting new jobs in the spool queue. It is frequently convenient
61 to turn spooling off while testing new line printer filters since the
65 to put jobs in the queue but no one else can.
66 The other main use is to prevent users from putting jobs in the queue
67 when the printer is expected to be unavailable for a long time.
72 allows ordinary users to restart printer daemons when
74 reports that there is no daemon present.
79 halts a spooling daemon after the current job completes;
80 this also disables printing. This is a clean way to shutdown a
81 printer to do maintenance, etc. Note that users can still enter jobs in a
82 spool queue while a printer is
88 places jobs at the top of a printer queue. This can be used
89 to reorder high priority jobs since
91 only provides first-come-first-serve ordering of jobs.
