1: Yes, I rebooted my pc after the upgrade before posting comment #2.
2: The HP Deskjet 6940 printer keeps working correctly.
3: I browsed through the wiki you gave me, checking if I could fix the pdf printer by myself, with no improvement. So I activated the error logging in the printing server. Attaching the error logs: if you look to "cups-pdf_log", you can see there are errors in setting file mode.
Hello Till,
1: Yes, I rebooted my pc after the upgrade before posting comment #2.
2: The HP Deskjet 6940 printer keeps working correctly.

I hope this can help fixing it! Thanks!
