How long does a set of ink cartridges last in a turned off printer?
How much does a replacement set of print cartridges cost?
The major failing with the last 3 ink-jet printers I have owned (Cannon, HP and Kodak) has been that if you leave them untouched for 3 months then come back to print something the ink has dried all over the heads and you need to buy new.
Often a new printer is cheaper than a set of ink-cartridges.
Now I send them off to snapfish or take them to the local print-shop, it's cheaper and gets better results.
