The number 364 for the cartridge is true anscheind not match for each printer. I have the HP Photosmart 5515. For these printers, the cartridge number is provided 364 and 364 XL. Unfortunately, the black cartridge does not fit in the holder for the cartridge. The other colors fit properly into the holder and functioning well. Thus, I give not only a star but 3. returning works then properly on Amazon.
