Just to add a bit of information to see if it helps:-
I used the gnome printer configuration to delete the printer and re-install. The system searches for the driver and then states:-
Printer 'Photosmart-C4380-series' requires the 'foomatic-rip-hplip' program but it is not currently installed. Please install it before using this printer.
I was wondering if the foomatic-rip-hplip program was missing because the hplip installation stopped short?
If so, how do I get around the problem?
