The problem: The printer hangs when i try to print a document (any type). At launchpad.net a ticket was submited with the same problem. A Suggestion, update to last version of hp-lib (the actual version es 3.10.5). Run hp-check -t (the first line says your installed version) Update to your last version using Synaptic, searching for hp as keyword. The solution: change the default: hp:/usb/photosmart_7200_series?serial=XXXXXXXXXXXX to: usb://hp/photosmart%207200%20series?serial=XXXXXXXXXXXX Edit this from System->Administration->Printing Select the desire printer-> Properties Under device Uri: edit what i said before. Note: XXXXXXXXXXXX is written by default, copy it straightforward Its represent your printer serial number. This solution was submitted by ben_reily at launchpad
