NAME

       lpsched,  lpshut,  lpmove,  lpfence - start the LP request scheduler; stop the LP request scheduler; move requests between LP destinations;
       define the minimum priority for printing

SYNOPSIS


       requests dest

       dest1 dest2

       printer fence

DESCRIPTION

       Schedules requests taken by
		   for printing on printers.  is typically invoked in This creates a process which runs in the background until is executed.   The
		   activity of the process is recorded in

		   recognizes the following options:

		      Write a verbose record of the
			    process on

		      Write logging data on

       Shuts down the printer scheduler.
		   All printers that are printing at the time is invoked stop printing.  Requests that were printing at the time the scheduler was
		   shut down are reprinted in their entirety after is started again.  All LP commands perform their functions  even  when  is  not
		   running.

       Moves requests that were queued by
		   between LP destinations.

		   The	first  form  of the command moves the named requests to the LP destination, dest.  requests are request IDs as returned by
		   The requests that are currently printing will not be moved.

		   The second form of the command moves all requests for destination dest1, including requests that  are  currently  printing,	to
		   destination dest2.  As a side effect, dest1 rejects all subsequent requests.

		   Note that never checks the acceptance status (see accept(1M)) for the new destination when moving requests.

       Defines the minimum required
		   priority  for  the  spooled file to be printed.  fence must be in between 0 (lowest fence) and 7 (highest fence).  Each printer
		   has its own fence, which is initialized to 0 when it is configured by the command.

       able.   If  is  not  specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of If any internationalization
       variable contains an invalid setting, the commands behave as if all internationalization variables are set to "C".  See environ(5).

EXAMPLES

	      Move requests and from destination queues and to the destination queue if the requests are not currently printing.

	      Move all requests from the destination queue laserjet1 to the destination queue laserjet2.  This will also cause laserjet1 to reject
	      all subsequent print requests to it.  All currently printing requests from laserjet1 will be reprinted on laserjet2.

	      Suppose is a member of classes and Running this command will cause only print requests of priority 5 and above from queues and to be
	      printed on printer Print requests of priority 4 and below will not be picked by the scheduler for printing on

WARNINGS

       and perform their operation on the local system only.
