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 system.  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 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 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 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.

FILES

DIAGNOSTICS

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