lpc - line printer control program
/usr/ucb/lpc [ command
[ parameter... ] ]
SUNWscpu
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. Specify the printer parameter by the name of
the printer (for example, as lw), not as you would specify it to lpr(1B)
or lpq(1B)
(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(1B)
)
for the specified printers. The abort command can only be used by the super-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 super-user.
- disable
- [all| [printer...]]
Turn the specified printer queues off. This prevents new printer jobs from
being entered into the queue by lpr(1B)
. 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 does not need to be quoted, and
the remaining arguments are treated like echo(1)
. This is normally used
to take a printer down and let others know the reason (lpq(1B)
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(1B)
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.
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.

- ?Ambiguous
command
- The abbreviation you typed matches more than one command.
- ?Invalid
command
- You typed a command or abbreviation that was not recognized.
- ?Privileged
command
- You used a command can be executed only by the super-user.
- lpc: printer:
unknown printer to the print service
- The printer was not found in the LP
database. Usually this is a typing mistake; however, it may indicate that
the printer does not exist on the system. Use ‘lpstat -p’ (see lpstat(1)
) or
the status command (see Commands above) to discover 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 to see 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.
