Well I learned the hard way again that HP printers are designed to ditch other manufacturers' inks. I first bought a half price recycled cartridge - and IT WORKS, but every time I printed I got a message saying I didn't use HP ink. I had to keep pressing the 'next' button! This is from design types (same experience with ex-hp printers). They deliberately make it a hassle to use cheaper but equally functional inks. HP inks work but are TOO EXPENSIVE. I gave it 3 stars because of the cost from HP and the pitfalls with cartridges from other manufacturers.
