6 lpc - line printer control program
7
9 /usr/sbin/lpc [ command [ argument ... ] ]
10
12 Lpc is used by the system administrator to control the operation of the
13 line printer system. For each line printer configured in /etc/print‐
14 cap, lpc may be used to:
15 · disable or enable a printer,
17 · disable or enable a printer's spooling queue,
19 · rearrange the order of jobs in a spooling queue,
21 · find the status of printers, and their associated spooling
23 queues and printer dameons.
24 Without any arguments, lpc will prompt for commands from the standard
26 input. If arguments are supplied, lpc interprets the first argument as
27 a command and the remaining arguments as parameters to the command.
28 The standard input may be redirected causing lpc to read commands from
29 file. Commands may be abreviated; the following is the list of recog‐
30 nized commands.
31 ? [ command ... ]
33 help [ command ... ]
35 Print a short description of each command specified in the argu‐
36 ment list, or, if no arguments are given, a list of the recog‐
37 nized commands.
38 abort { all | printer ... }
40 Terminate an active spooling daemon on the local host immedi‐
41 ately and then disable printing (preventing new daemons from
42 being started by lpr) for the specified printers.
43 clean { all | printer ... }
45 Remove any temporary files, data files, and control files that
46 cannot be printed (i.e., do not form a complete printer job)
47 from the specified printer queue(s) on the local machine.
48 disable { all | printer ... }
50 Turn the specified printer queues off. This prevents new
51 printer jobs from being entered into the queue by lpr.
52 down { all | printer } message ...
54 Turn the specified printer queue off, disable printing and put
55 message in the printer status file. The message doesn't need to
56 be quoted, the remaining arguments are treated like echo(1).
57 This is normally used to take a printer down and let others know
58 why (lpq will indicate the printer is down and print the status
59 message).
60 enable { all | printer ... }
62 Enable spooling on the local queue for the listed printers.
63 This will allow lpr to put new jobs in the spool queue.
64 exit
66 quit
68 Exit from lpc.
69 restart { all | printer ... }
71 Attempt to start a new printer daemon. This is useful when some
72 abnormal condition causes the daemon to die unexpectedly leaving
73 jobs in the queue. Lpq will report that there is no daemon
74 present when this condition occurs. If the user is the super-
75 user, try to abort the current daemon first (i.e., kill and
76 restart a stuck daemon).
77 start { all | printer ... }
79 Enable printing and start a spooling daemon for the listed
80 printers.
81 status { all | printer ... }
83 Display the status of daemons and queues on the local machine.
84 stop { all | printer ... }
86 Stop a spooling daemon after the current job completes and dis‐
87 able printing.
88 topq printer [ jobnum ... ] [ user ... ]
90 Place the jobs in the order listed at the top of the printer
91 queue.
92 up { all | printer ... }
94 Enable everything and start a new printer daemon. Undoes the
95 effects of down.
