9.4. Problem Management - abort, redo, kill

These commands are usually used when there is a problem printing a job. The abort command is used to kill off all printing activity associated with a job. It also has the side effect of stopping printing on the print queue. The redo command will redo or attempt to reprint a job. The kill command combines the abort and redo command, and is useful when there are problems with the job currently being printed and it should be reprinted.
