Crazy Printers

Suddenly, our printers are getting nuts.

We have 5 HP LaserJet Printers connected directly to the LAN.

For mostly users, Printers only print graphics and frames, nothing of text. Some users can print without problems.

For instance, user A prints the xxx document perfectly. User B prints exactly the same document from the same location but logged in with his account, and the printer only prints the graphics and the shapes, nothing of text.

Seems like some users don?t has rights to: ???

Does anybody has this problem before?
