Summary: I have hp photosmart 7510, it takes the 364 cartridges. It can take the fat black print ink, which this comes with, but it doesn't come with the thinner black photo "colour" ink and the fsttet cartridge doesn't fit into the photo cartridge slot. Had to order elsewhere ( interestingly you can get the photo ink in XL size but in a narrow cartridge...!
Summary: This ink. Is more than what you think! Easy to load. When printer in off mode. Tell all your friends. To lay down their pens. Printing is fun, So lets get it done. This is ink is so good, Could have it for pud.
