Canon
I have a Canon MX492. You can refill the cartridges and there is a little routine you do once (IIRC Canon even tells you how to do it) and it'll use the 'empty' cartridges forever. Plugs up sometimes but then I bought a $100 Ultrasonic cleaner to clean the old ones and with the cartridges costing $40 to $50 each around here that gets paid for real quick. (And I can use it for cleaning old carburetors too.)
