Printer cartridge Non-reusable. Why and how? Last cartridge lasted 3 years. New one, 1 month and refill is fruitless.?
I refilled a cartridge a thousand times until it just wore out. Purchased new (black) cartridge, used it, attempted refill & can't make the thing print for love or money. It's an HP cartridge but it's sure different from my old one. How are they doing this and is there a bypass?
Thanks for any help,
