Plus, you won't have to worry about running out of ink in the middle of a print. Just look at the translucent case of the cartridge. If the ink levels are low, add ink anytime - even when the printer is running.
Other bulk-ink systems while sometimes convenient (holding more ink) are MUCH more expensive and can run into the thousands of dollars.
