lenny to squeeze upgrade - printer not working

[Filipe Freire <freirefil@gmail.com>]

Hi

just upgraded from lenny to squeeze and the printer is not working.  I manage it via http://localhost:631

jobs are sent and lpq says that they are printing but in cups the printer status is Processing - "Printer is offline."

needless to say eveything was working fine before the upgrade.  Tried restarting cups and lpd but did not make a difference.  The  printer is a HP Deskjet 6500.

Any suggestions, shared experiences are welcome.

Best
Filipe
