The cannons are not a true ink jet. They are a bubble jet. Although I can't remember exactly what the difference is. Their cartidges are just ink tanks that feed their nozzles. This makes them alot less expensive, plus you get alot more ink then you get in the tri color cartidges. Another benefit is that if you print alot of red you can buy the one color.
With Lexmark and HP you are changing the print heads every time you change the cartridge.
I have only seen Cannon printers however. I haven't seen a multifunction device.
