Thanks for the pointer. I usually use "lprm" and always thought that
removing a job also removes all spool files. I did not know about the
command cancel, whose name does not lead to beeing printing specific
(neither starts with cups nor with lp).
Do you think implying "-x" with with lprm would be a worthwile
wishlist bug for upstream?

Neither are currently explicitly set. But the man page says that
PreserveJobFiles has a default value of 1 day and PreserveJobHistory
is yes. Maybe PreserveJobFiles only applies to sucessfully printed
jobs?

Just to be clear: I should first try out PreserveJobHistory? And after
a day all spool files should be gone (if it works)?
