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: Prints a short description of each command specified in the argument list or, when no
       arguments  are  supplied, a list of the recognized commands.  Prints a short description of each command specified in the argument list or,
       when no arguments are supplied, a list of the recognized commands.  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.  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.  Turns the specified printer queues off. This prevents new printer jobs from being entered into the queue by lpr or lp.
       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.)  Enables spooling on the local  queue  for  the
       listed  printers.   This  allows  lpr  or  lp  to put new jobs in the spool queue.  Exit from lpc.  Exit from lpc.  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.
       Enables printing and starts a spooling daemon for the listed printers.  Displays the status of daemons and queues  on  the  local  machine.
       When  printer  name parameters are not supplied, information about all printers is provided.  Stops a spooling daemon after the current job
       has completed and disables printing.  Places jobs in the order listed at the top of the printer queue.  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.  Abbreviation matches more than one command.  No match was found.  Command may be executed
       by the superuser only.

FILES

       Specifies the command path.  Specifies the printer description file.  Specifies print spool directories.  Specifies the lock file for queue
       control.
