I have had an HP7280 "All In One" Printer. since Nov "08", I never could get it working on my old XP..( YES! Never worked, system continued to say " file Missing, etc") Now I Have a New Dell Studio Desk Top and system now says the printer is incompatible with the Desk Top...

. What can I do to make this work. Please be as clear as possible, as though you wre talking to a child - Any help will be appreciated, Buying a new printer is out of the question. Help Help Help........
