Ink cartridges for at-home inkjet printers can be very expensive. One way to conserve ink is to automatically set your printer default to draft mode when the overall quality of the printing really doesn't matter; this uses less ink and will help extend the life of the cartridge. Another way to go green and save money is to replace your inkjet cartridges with remanufactured cartridges. These are recycled cartridges that are refilled and resold at up to 60 percent less than new ones. Try the site carrotink.com to see the savings yourself.
