NAME
     lpc - line printer control program

SYNOPSIS
     /bsd43/bin/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 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 com-
          plete 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 condi-
          tion 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
