NAME
lpc - (BSD) 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(1BSD)
or lpq(1BSD) (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(1BSD)) for the
specified printers. The abort command can only be used
by a 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 a
privileged user.

disable [all | [printer . . . ]]
Turn the specified printer queues off. This prevents
new printer jobs from being entered into the queue by
lpr(1BSD). The disable command can only be used by a
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(1BSD)
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(1BSD) can put new jobs in the
spool queue. The enable command can only be used by a
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
a 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 a 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 a
privileged user.
up [all | [printer . . . ]]
Enable everything and start a new printer daemon.
Undoes the effects of down.

DIAGNOSTICS
?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
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.
