I buy 2 packs of ink for our church printer so we never run out of ink. This is an old printer and I have messed up printers before using refilled ink so I only buy real ones now. They work with no problems and every time I put in the last cartridge I order a new one so I don't run out (since several people in the building use the printer this is a must).
