Ink cartridges for ink jet printers are kind of expensive. Each one is supposed to last for 400 pages, but it doesn't seem like it actually does. The printer also uses up a lot of ink in the "cleaning" process. Plus, if you don't use up the cartridge within a certain number of months, the ink expires and you have to replace it with a new one. Doesn't seem to be very cost effective...
