1. The term Dot matrix refers to the process of using dots to form an image. In a dot matrix image, the image quality is determined by the number of dots per inch.

2. Alternatively referred to as a pin printer, Dot matrix printers were first introduced by Centronicsin 1970. Dot matrix printers use print heads to shoot ink or strike an ink ribbon to place hundreds to thousands of little dots to form text and images. Today, Dot matrix printers are rarely used or found because of the low quality print compared to ink jet printers and laser printers.
