c (control or history) files and d (document) files. They should get
cleared with 'cancel -a -x' but might need to be removed with 'rm'.

cupsd.conf(5) explains the PreserveJobFiles and PreserveJobHistory
directives. If you put "PreserveJobFiles 30" in cupsd.conf, does it
work for you?

You may, of course, alter the default PreserveJobHistory value too
but are then likely to hit Bug#921741. Knowing how much of Emin Kaya's
issue you can replicate would be useful.

Brian.
