NAME
       lpc - line printer control program

SYNOPSIS
       /usr/etc/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   the
       printcap(5) database lpc may be used to:

       ·      disable or enable a printer,

       ·      disable or enable a printer's spooling queue,

       ·      rearrange the order of jobs in a spooling queue,

       ·      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  abbreviated;  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.
