Since the 7221 uses the rather old HP binary format I would like convert it to a 7220 which is hpgl. I know this has been done before by changing at least the ROM board. Does anyone know how this is done and the approximate price? How about a number and/or name at HP I can call? Part numbers? Any help will be sincerely appreciated. Thank you.
