My purchase of HP ink waslong overdo. I was surprised by the expese attached to the ink. It's probably cheaper to buy a new printer when your ink runs out. My recommendation would be to investigate all your options before buying a new printer.
This is the only refill that my printer can use. Most of the time it seems to be a never ending cartridge and then other times it is gone almost as soon as I put it in. But it gives good quality of a print so we are happy.
