I have an HP DeskJet 845C printer.
It worked very well in Gutsy Gibbon (7.10), and still works if I boot from Gutsy Gibbon DVD.
Some time ago I upgraded to Hardy Heron (8.04) and it doesn't work anymore, if I try to print, it just prints strange symbols.
It tried to uninstall (purge) all cups and lpr related packages, reboot, and reinstall them, but the situation is the same.
What can I do?
