Printers are one of the most popular tools in the world, because they are inexpensive, yet highly versatile. The one drawback is the cost of the cartridges. Two of these can cost as much as a whole printer, and they are difficult to refill because of the new "smart technology" which is built into the printers that keep track of the ink level. Once the cartridge is empty, this technology also will not allow you to simply refill the cartridge with ink, because it will still think that the cartridge is empty. But I'll show you how easy it is to refill your printer cartridge and fool the printer into thinking your cartridge is always full, which allows you to refill your own cartridges with inexpensive ink and save a LOT of money!
