lpsched, lpshut -- start/stop the print service

Syntax

/usr/lib/lpsched [-d] [-f int] [-n int] [-r int] [-s]

/usr/lib/lpshut

Description

lpsched starts the LP print service.

lpsched takes the following options:

-d: Debug mode; log all messages between lp and lpsched to /usr/spool/lp/logs/messages, log all requests submitted to /usr/spool/lp/logs/requests, and log all commands executed by lpsched to /usr/spool/lp/logs/exec.
-f int: Increase the number of slow filters that can run concurrently by int (see lpfilter(ADM)).
-n int: Increase the number of notifications that can run concurrently by int (see the -m and -w options of lp(C)).
-r int: Increase the margin of reserved file descriptors used by the scheduler by int.
-s: Do not trap most signals; disables interrupt, hangup, quit, terminate, child, and alarm signals.

lpshut shuts down the print service. All printers that are printing at the time lpshut is invoked will stop printing. When lpsched is started again, requests that were printing at the time a printer was shut down will be reprinted from the beginning.

Only root can start or stop the print service; user lp cannot.

Starting and stopping of the print service are logged in the file /usr/spool/lp/logs/lpsched.

Limitations

By default, the directory /usr/spool/lp is used to hold all the files used by the print service. This can be changed by setting the SPOOLDIR environment variable to another directory before running lpsched. If you do this, you should populate the directory with the same files and directories found under /usr/spool/lp; the print service will not automatically create them. Also, the SPOOLDIR variable must then be set before any of the other print service commands are run.
