Garbaged printing with black squares after Jaunty Upgrade

[Luca Maranzano]

Binary package hint: cups

After upgrade from 8.10 to 9.04, whenever I print a document on a Ricoh printer mapped via SMB share which was working perfectly on 8.10, I get some character replaced by a black square as big as the charatect (please see the attached scan in pdf to better undrestand what I mean).

Cups version:
cups:
  Installed: 1.3.9-17ubuntu3
  Candidate: 1.3.9-17ubuntu3
  Version table:
 *** 1.3.9-17ubuntu3 0
        500 http://it.archive.ubuntu.com jaunty-updates/main Packages
        100 /var/lib/dpkg/status
     1.3.9-17ubuntu1 0
        500 http://it.archive.ubuntu.com jaunty/main Packages

My difficult is that I don't know exactly which package may be the problem, so I'm submitting this bug to cups, but may be it is not cups related.
Please let me know how I can provide more info to investigate better the problem.

Thank you.
Cheers,
Luca
