[lpsched]
Use this command to start the line printer daemon, generally after the service has been stopped with lpshut. Only one lpsched daemon should be running at a time.

This command lets you start the line printer daemon in "debug" mode. Debug output is written to the following files:
/usr/spool/lp/logs/messages
/usr/spool/lp/logs/requests
/usr/spool/lp/logs/exec
