cups permission or what ???

[Couannette]

Hi,

I updated my Lunar a few days ago and now I can't print anything with
CUPS. I know that I modified some files and permissions in /etc/cups and
in /var/spool/cups months ago but I can't remember :(.

All that I can stat is that my printers are correctly set up.
Attached file is a ps axf just after launching a print command.

Please give me some clues 'cause this gives me headaches!
