NAME
       lpc - line printer control program

SYNOPSIS
       /usr/sbin/lpc [ command [ argument ... ] ]

DESCRIPTION
       Lpc  is used by the system administrator to control the operation of the line printer sys-
       tem.  For each line printer configured in /etc/printcap, lpc may be used to:

       o      disable or enable a printer,

       o      disable or enable a printer's spooling queue,

       o      rearrange the order of jobs in a spooling queue,

       o      find the status of printers, and their associated spooling queues and printer dame-
	      ons.

       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 abreviated; 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  mes-
	      sage).

       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.

FILES
       /etc/printcap	       printer description file
       /usr/spool/*	       spool directories
       /usr/spool/*/lock       lock file for queue control

SEE ALSO
       lpd(8), lpr(1), lpq(1), lprm(1), printcap(5)

DIAGNOSTICS
       ?Ambiguous command      abreviation matches more than one command
       ?Invalid command        no match was found
       ?Privileged command     command can be executed by root only
