lpc - line printer control program
SYNOPSIS
/usr/etc/lpc
[
command
[
parameter...
] ]
DESCRIPTION
lpc
controls the operation of the printer, or of multiple printers,
as described in the
/etc/printcap
database.
lpc
commands can be used to start or stop a printer, disable or enable
a printer's spooling queue, rearrange the order of jobs in a queue,
or display the status of each printer--along with its
spooling queue and printer daemon.
With no arguments,
lpc
runs interactively, prompting with
lpc>.
If arguments are supplied,
lpc
interprets the first as a
command
to execute; each subsequent argument is taken as a
parameter
for that command.
The standard input can be redirected so that
lpc
reads commands from a file.
USAGE
Commands
Commands may be abbreviated to an unambiguous substring. Note: the
printer
parameter is specified just by the name of the printer (as
lw),
not as you would specify it to
lpr.1
or
lpq.1
(not as
-Plw).
- ?
[command]...
-
- help
[command]...
-
Display a short description of each
command specified in the argument list,
or, if no arguments are given, a list of the recognized commands.
- abort
[all|
[printer...]]
-
Terminate an active spooling daemon on the local host immediately and
then disable printing (preventing new daemons from being started by
lpr.1
for the specified printers. The
abort
command can only be used by the super-user.
- clean
[all|
[printer...]]
-
Remove all files with names beginning with
cf,
tf,
or
df
from the specified printer queue(s) on the local machine. The
clean
command can only be used by the super-user.
- disable
[all|
[printer...]]
-
Turn the specified printer queues off. This prevents new
printer jobs from being entered into the queue by
lpr.1
The
disable
command can only be used by the super-user.
- down
[all|
[printer...]]
[message]
-
Turn the specified printer queue off, disable printing and put
message
in the printer status file. The message doesn't need to be
quoted, the
remaining arguments are treated like
echo.1v
This is normally used to take a printer down and let others know why
(lpq(1)
indicates that the printer is down, as does the
status
command).
- enable
[all|
[printer...]]
-
Enable spooling on the local queue for the listed printers, so that
lpr.1
can put new jobs in the spool queue. The
enable
command can only be used by the super-user.
- exit
-
- quit
-
Exit from
lpc.
- restart
[all|
[printer...]]
-
Attempt to start a new printer daemon. This is useful when some abnormal
condition causes the daemon to
die unexpectedly leaving jobs in the queue.
lpq.1
reports that there is no daemon present when this condition occurs.
This command can be run by any user.
- start
[all|
[printer...]]
-
Enable printing and start a spooling
daemon for the listed printers. The
start
command can only be used by the super-user.
- status
[all|
[printer...]]
-
Display the status of daemons and queues on the local machine.
This command can be run by any user.
- stop
[all|
[printer...]]
-
Stop a spooling daemon after the current
job completes and disable printing. The
stop
command can only be used by the super-user.
- topq
printer
[job#...]
[user...]
-
Move the print job(s) specified by
job#
or those job(s) belonging to
user
to the top (head) of the printer queue. The
topq
command can only be used by the super-user.
- up
[all|
[printer...]]
Enable everything and start a new printer daemon. Undoes the
effects of
down.
