I don't know what's caused this, but an Epson Stylus C66 that worked perfectly well under Hardy has suddenly stopped working under Intrepid. The GNOME utilities aren't very helpful with figuring out what's wrong, but they seem to be saying that the colorspace being used is invalid for the printer. I've never specified any such thing, so I'm assuming a bad default got set during the upgrade. What do I do to change this?
