|Thanks, the administration pages are now accessible but still can't print. I tried removing cups entirely and re-installing but still no joy. I'm running a Dell 2320 All in One with Sandy Bridge integrated graphics. Looking at the printer page I see an error message on the print job that says
Paused - "File "/usr/lib/cups/filter/hpcups" not available: No such file or directory"
aptitude search hpcups
