lprm cancels print jobs that have been queued for printing. The -P
option specifies the destination printer or class.
If no arguments are supplied, the current job on the default destination is
cancelled. You can specify one or more job ID numbers to cancel those jobs,
or use the - option to cancel all jobs.
The -E option forces encryption when connecting to the server.
COMPATIBILITY
The CUPS version of lprm is compatible with the standard Berkeley
lprm command.
