* Are there any use cases missing? Canceling print jobs.
By default a user can cancel his own print jobs on his local host according to the CUPS "default" policy in /etc/cups/cupsd.conf but even more: Only FYI (of course not obvious for average users): normal_user@host $ cancel -U root queue_name-job_number See "man cancel": ------------------------------------------------------------------------ -U username Specifies the username to use when connecting to the server. ... -u username Cancels jobs owned by username. NOTES Administrators wishing to prevent unauthorized cancellation of jobs via the -u option should require authentication for Cancel-Jobs operations in cupsd.conf(5). ------------------------------------------------------------------------ Background information: As long as the IPP communication with the cupsd happens without authentication of the user name, any user can set an arbitrary user name for the IPP communication. But if the IPP communication with the cupsd requires authentication, any user must authenticate first of all which is less user-friendly but that is the only way if you cannot trust your users.
