1) Ubuntu Release
Description: Ubuntu 16.04.3 LTS
Release: 16.04

2) Version of the package
cups:

  Version table:

3) What I expected to happen:
from man cupsd.conf

      PreserveJobFiles Yes

       PreserveJobFiles No

       PreserveJobFiles seconds
            Specifies whether job files (documents) are preserved after a job is printed. If a numeric value is specified, job files are preserved
            for the indicated number of seconds after printing. The default is "86400" (preserve 1 day).

       PreserveJobHistory Yes

       PreserveJobHistory No

       PreserveJobHistory seconds
            Specifies whether the job history is preserved after a job is printed. If a numeric value is specified, the job history is preserved for
            the indicated number of seconds after printing. If "Yes", the job history is preserved until the MaxJobs limit is reached. The default
            is "Yes".

4) What happens instead....

If I put the following directives in cupsd.conf the job files and history are deleted immediately.

PreserveJobFiles 604800
PreserveJobHistory 604800

Debug log showing history being purged:
