A:AnswerThe Envy Photo 7855 printer uses the 64 ink cartridges. They will print up to 200 pages in black and up to 165 pages in color. As far as photos go it will depend on what size photo you are printing, however photos use a lot more ink than a standard page so you get significantly fewer photos out of the ink cartridges.
