A:AnswerSorry, not that I'm aware... generally though, you get what you pay for when you go cheap. Might be less out of pocket but no guarantee they will last as long. Stick with the HP cartridges.
A:AnswerGreat question. The 564 ink is what you need for the HP PhotoSmart 7520. The printer also takes a photo black and a regular black cartridge so both blacks would be needed for this printer. The photo black is used for printing photos and the regular black is for documents.
I hope this helps!
