Product: HP Photosmart 7515 e-All-in-One Printer - C311a
Operating System: macOS 10.14 Mojave
Why is the there no packages that contain each of the five cartridges I need? They are bunched so we have to buy multiples of each, of course. The attendant at Office Max gave up trying to find the Photo and distinguish it from the simple Black. Why is this? Every time I run out of ink I have to begin this useless game all over again. Five cartridges in one package - what's wrong with that?
