I like many am a great believer in re-cycling my old printer cartridge and re-use by filling up with my own ink. HP on the other hand want me to purchase a new cartridge and make life difficult for the Re-users by not showing the re-plendished ink level.

I know that there are 'Zappers' out there or chips that are supposed to do just that but as yet I can't find one for this printer.

Has anyone overcome this problem?
