Inkjet printers were first introduced to the general public in the second half of the 1980’s. Although expensive at the time of their introduction their price has been steadily decreasing as their popularity grows. Now that it is possible to find a inkjet printer of reasonable quality for as little as thirty dollars they have become a common office appliance in most American households.
The basic concept of the inkjet printer is to use the smallest possible drop of ink to leave the clearest possible image on a piece of paper. Words and images are printed on paper using a dot matrix system. The dots are smaller in diameter then a human hair. They are placed with such precision that they are becoming popular in the growing field of digital photography.
There are three types of Epson printer ink cartridge designed to work in an inkjet printer. A thermal cartridge that uses a heating element to warm the ink and force it through the cartridge head, a continues ink release method, and the piezoelectric system which uses a crystal that changes shapes to drop a tiny amount of ink onto a piece of paper.

The Epson printer ink cartridge is designed with the piezoelectric system. As current passes through the cartridge the crystal changes shape. The shape shifting crystal creates a pressure pulse. The pressure pulse forces a tiny drop of ink from the cartridge, leaving a miniscule dot of ink on the paper.
The Epson printer ink cartridge features a fixed head. These fixed heads use micropiezo technology. Epson has been successfully employing this type of technology in its ink cartridges for years. The downside to the fixed head is that if the head breaks the whole product has to be thrown away.

The biggest drawback in the Epson printer ink cartridge is that the technology is traditionally more expensive and is harder to sustain then a thermal method.
The most positive thing about the ink cartridges for Epson printers is the clear print quality and the vast variety of color choices. Microchips attached to the cartridges ease communication between the printer and the cartridge. This information is then relayed through the USB port to the computer to tell the consumer how much ink is left in each individual cartridge.
