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
       /etc/printcap, 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; 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.
