LPC(8)LPC(8)NAMElpc - line printer control program
SYNOPSIS
/usr/etc/lpc [ command [ argument ... ] ]
DESCRIPTION
Lpc is used by the system administrator to control the operation of the
line printer system. For each line printer configured in the
printcap(5) database lpc may be used to:
· disable or enable a printer,
· disable or enable a printer's spooling queue,
· rearrange the order of jobs in a spooling queue,
· find the status of printers, and their associated spooling
queues and printer dameons.
Without any arguments, lpc will prompt for commands from the standard
input. If arguments are supplied, lpc interprets the first argument as
a command and the remaining arguments as parameters to the command.
The standard input may be redirected causing lpc to read commands from
file. Commands may be abbreviated; the following is the list of
recognized commands.
? [ command ... ]
help [ command ... ]
Print 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) for the specified printers.
clean { all | printer ... }
Remove any temporary files, data files, and control files that
cannot be printed (i.e., do not form a complete printer job)
from the specified printer queue(s) on the local machine.
disable { all | printer ... }
Turn the specified printer queues off. This prevents new
printer jobs from being entered into the queue by lpr.
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(1).
This is normally used to take a printer down and let others know
why (lpq will indicate the printer is down and print the status
message).
enable { all | printer ... }
Enable spooling on the local queue for the listed printers.
This will allow lpr to put new jobs in the spool queue.
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 will report that there is no daemon
present when this condition occurs. If the user is the super-
user, try to abort the current daemon first (i.e., kill and
restart a stuck daemon).
start { all | printer ... }
Enable printing and start a spooling daemon for the listed
printers.
status { all | printer ... }
Display the status of daemons and queues on the local machine.
stop { all | printer ... }
Stop a spooling daemon after the current job completes and
disable printing.
topq printer [ jobnum ... ] [ user ... ]
Place the jobs in the order listed at the top of the printer
queue.
up { all | printer ... }
Enable everything and start a new printer daemon. Undoes the
effects of down.
