LPC(8)                      System Manager's Manual                     LPC(8)



NAME
       lpc - line printer control program

SYNOPSIS
       /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/print-
       cap, lpc may be used to:

       o      disable or enable a printer,

       o      disable or enable a printer's spooling queue,

       o      rearrange the order of jobs in a spooling queue,

       o      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  recog-
       nized commands.

       ? [ command ... ]

       help [ command ... ]
              Print a short description of each command specified in the argu-
              ment list, or, if no arguments are given, a list of  the  recog-
              nized commands.

       abort { all | printer ... }
              Terminate  an  active  spooling daemon on the local host immedi-
              ately and then disable printing  (preventing  new  daemons  from
              being started by lpr) for the specified printers.

       clean { all | printer ... }
              Remove  all  files beginning with ``cf'', ``tf'', or ``df'' from
              the specified printer queue(s) on the local machine.

       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.

       disable { all | printer ... }
              Turn  the  specified  printer  queues  off.   This  prevents new
              printer jobs from being entered into the queue by lpr.

       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.

       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  dis-
              able printing.

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

FILES
       /etc/printcap           printer description file
       /usr/spool/*            spool directories
       /usr/spool/*/lock       lock file for queue control

DIAGNOSTICS
       ?Ambiguous command      abreviation matches more than one command
       ?Invalid command        no match was found
       ?Privileged command     command can be executed by root only
