How the lpsched Daemon Tracks the Status of Print Requests

The lpsched daemon on both the print server and print client keeps a log of each print request that it processes and notes any errors that occur during the printing process. This log is kept in the /var/lp/logs/lpsched file. Every night, the lp cron job renames /var/lp/logs/lpsched to a new lpsched.n file and starts a new log file. If errors occur or jobs disappear from the print queue, you can use the log files to determine what lpsched has done with a printing job.
