Have you wondered how much your printer will cost over time? If you want to know, you can check how many pages you print every week. Then multiply that by 52 weeks, to reach a year’s total. Divide that figure with the cartridge page yield to find out the number of cartridges you will need per year. If you print 25 pages per week, you’d print 1300 pages per year. If your cartridge can print 200 copies, you will need to buy 7 cartridges in a year to print 1300 pages. To cut down on ink jet cartridge purchases, you can choose to buy compatible ink jet cartridges instead of original cartridges.
