So how can you save money on print cartridges?

One of the easiest way to save money on printing supplies is to lower the print quality in your settings (usually Draft mode or similar). This will considerably use less ink at the expense of the print quality. However, certain printouts such as documents may be worth to be printed using this option. The second way to save money is ofcourse to purchase Remanufactured or Compatible cartridges over expensive OEM ones.
