Bug Description

I am moving the discussion done in bug 444597 to its own bug report as bug 444597 describes another problem.

In the home directory of the user "lp" which is the system user of CUPS under which the print jobs are executed an HPLIP configuration directory .hplip/ is created. "lp"s home directory is /var/spool/cups/tmp/ under Ubuntu (and probably also under Debian) and /var/spool/lpd/ under SUSE. Usually on job execution only CUPS filters and backends are run and these should not create any files or directories or at least remove them when they terminate. The "lp" user is only used for print jobs, for nothing else. Print queue setup or other administrative tasks are done by root or by any user in the "lpadmin" group, never by "lp". So the "hp-*" utilities of HPLIP should not be run by "lp".
