lpc(1M) (BSD Compatibility Package) lpc(1M)
NAME
lpc - line printer control program
SYNOPSIS
/usr/ucb/lpc [ command [ parameter... ] ]
DESCRIPTION
lpc controls the operation of the printer, or of multiple printers.
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.
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 privileged user.
clean [all| [printer...]]
Remove all files created in the spool directory by the daemon
from the specified printer queue(s) on the local machine. The
clean command can only be used by the privileged 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 privileged user.
down [all| [printer...]] [message]
Turn the specified printer queue off, disable printing and put
message in the printer status file. The message does not 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(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 privileged 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. 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 privileged
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
privileged 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 privileged user.
up [all| [printer...]] Enable everything and start a new printer
daemon. Undoes the effects of down.

?Invalid command
You typed a command or abbreviation that was not recognized.
?Privileged command
You used a command can be executed only by the privileged user.
lpc: printer: unknown printer to the print service
The printer was not found in the System V LP database. Usually
this is a typing mistake; however, it may indicate that the
printer does not exist on the system. Use `lptstat -p' to find
the reason.
lpc: error on opening queue to spooler
The connection to lpsched on the local machine failed. This
usually means the printer server started at boot time has died
or is hung. Check if the printer spooler daemon
/usr/lib/lp/lpsched is running.
lpc: Can't send message to LP print service
lpc: Can't receive message from LP print service
These indicate that the LP print service has been stopped. Get
help from the system administrator.
lpc: Received unexpected message from LP print service
It is likely there is an error in this software. Get help from
system administrator.
