I have problem.
Lubuntu 12.04 in virtualbox 4.1.10 r76836, host is windows xp sp3. Printer HP LaserJet P1006, with driver foo2xqx.
Sometimes the printer doesn't print. tasks go to queue and appear there with the status - is executed.
Here the log of the press of test page through debugging http://pastebin.com/xEpxy9XM
Noticed if to disconnect the printer from virtualbox, to print in windows, it starts to print in linux.
