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.

  check [all |	printer ...]
      [Tru64 UNIX]  Examines the printer description file and other
      components of the printing environment for potential configuration
      errors for each named printer.

      A diagnostic message for each possible problem found is displayed. The
      file name containing a possible problem precedes the message;
      otherwise, the name of a printer with a possible problem precedes the
      message. If no problems were detected, the message No configuration
      problems found is displayed.

      The check subcommand reports problems; it does not correct them.

      The check subcommand checks for the printer characteristic names that
      are listed in the Printer capability data base only; for further
      information, see the printcap(4) reference page. If lpc check finds a
      nonstandard printer characteristic name, it generates a diagnostic
      message even though the printer characteristic may be used correctly in
      a special user-written filter.

  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.

      Specifies the command path

  /etc/printcap
      Specifies the printer description file

  /usr/spool/*
      Specifies print spool directories
