lpc(8)
NAME
  lpc - Line printer control program

SYNOPSIS
  lpc [command [argument ...] ]

DESCRIPTION
  The lpc command is used by the system administrator to control the
  operation of the line printer system. For each line printer configured in
  the /etc/printcap file, the lpc command may be used for disabling or
  enabling a printer; disabling or enabling the printer spooling queue;
  rearranging the order of jobs in a spooling queue or finding the status of
  printers, their associated spooling queues, and the printer daemons.

  Without arguments, lpc prompts for commands from the standard input.	When
  arguments are supplied, lpc interprets the first argument as a command and
  any remaining arguments as command parameters. The standard input may be
  redirected so that lpc reads commands from a file.  The following is the
  list of recognized lpc commands:

  ? [command ...]
	    Prints a short description of each command specified in the
	    argument list or, when no arguments are supplied, a list of the
	    recognized commands.

  help [command ...]
	    Prints a short description of each command specified in the
	    argument list or, when no arguments are supplied, a list of the
	    recognized commands.

  abort [all | printer ...]
	    Terminates an active spooling daemon running on the local host,
	    and then disables printing. This prevents new daemons from being
	    started by lpr or lp for the specified printers.

  clean [all |	printer ...]
	    Removes any temporary files, data files, and control files that
	    cannot be printed (files that do not form a complete printer job)
	    from the specified printer queue(s) on the local machine.

  disable [all |  printer ...]
	    Turns the specified printer queues off. This prevents new printer
	    jobs from being entered into the queue by lpr or lp.

  down [all |  printer ...]  message ...
	    Turns the specified printer queue off, disables printing, and
	    puts a message in the printer status file. The message does not
	    need to be quoted because remaining arguments are treated the
	    same as echo.  The down command is normally used to take a
	    printer down and let others know why. (The lpq command indicates
	    that the printer is down and prints a status message.)

  enable [all | printer ...]
	    Enables spooling on the local queue for the listed printers.
	    This allows lpr or lp to put new jobs in the spool queue.

  exit	    Exit from lpc.

  quit	    Exit from lpc.

  restart [all | printer ...]
	    Attempts to start a new printer daemon. This is useful when some
	    abnormal condition causes the daemon to terminate unexpectedly
	    and leave jobs in the queue.  lpq reports that there is no daemon
	    present when this condition occurs.	 When a daemon is stuck, you
	    must first kill it and then restart.

  start [all |	printer ...]
	    Enables printing and starts a spooling daemon for the listed
	    printers.

  status [printer ...]
	    Displays the status of daemons and queues on the local machine.
	    When printer name parameters are not supplied, information about
	    all printers is provided.

  stop [ all | printer ...]
	    Stops a spooling daemon after the current job has completed and
	    disables printing.

  topq printer [jobnum ...] [user ...]
	    Places jobs in the order listed at the top of the printer queue.

  up [all |  printer ...]
	    Enables all printing and starts a new printer daemon. Cancels the
	    effect of the down command.

RESTRICTIONS
  Normally, the clean subcommand allows you to remove all print jobs on the
  system or all jobs on a specified printer.  However, clean does not remove
  the jobs in the spooling queues.  Therefore, you should use the lprm
  command on a printer-by-printer basis to remove the jobs you want to
  eliminate.

ERRORS
  The following diagnostic messages are possible.

  ?Ambiguous command
	    Abbreviation matches more than one command.

  ?Invalid command
	    No match was found.

  Privileged command
	    Command may be executed by the superuser only.

FILES
  /usr/sbin/lpc
	    Specifies the command path.

  /etc/printcap
	    Specifies the printer description file.

  /usr/spool/*
	    Specifies print spool directories.

  /usr/spool/*/lock
	    Specifies the lock file for queue control.
