Without any arguments, will prompt for commands from the standard input. If arguments are supplied, interprets the first argument as a command and the remaining arguments as parameters to the command. The standard input may be redirected causing to read commands from file. Com- mands may be abreviated; the following is the list of recognized commands. Print a short description of each command specified in the argument list, or, if no arguments are given, a list of the recognized commands. Terminate an active spooling daemon on the local host immediately and then disable printing (preventing new daemons from being started by for the specified printers. Remove any temporary files, data files, and control files that cannot be printed (i.e., do not form a complete printer job) from the spec- ified printer queue(s) on the local machine. Turn the specified printer queues off. This prevents new printer jobs from being entered into the queue by Turn the specified printer queue off, disable printing and put in the printer status file. The message doesn't need to be quoted, the remaining arguments are treated like This is normally used to take a printer down and let others know why will indicate the printer is down and print the status message). Enable spooling on the local queue for the listed printers. This will allow to put new jobs in the spool queue. Exit from lpc. 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. will report that there is no daemon present when this condition occurs. If the user is the super-user, try to abort the current daemon first (i.e., kill and restart a stuck daemon). Enable printing and start a spool- ing daemon for the listed printers. Display the status of dae- mons and queues on the local machine. Stop a spooling daemon after the current job completes and disable printing. Place the jobs in the order listed at the top of the printer queue. Enable everything and start a new printer daemon.
