A wire printer is a type of printer that uses wire elements to print on paper. There are different names for wire printers depending on their usage and the region they are used in. In the U.S., wire printers are also known as dot matrix printers, while in the U.K. they are referred to as matrix printers. Other synonyms for wire printers include impact printers, character printers, and line printers. Impact printers are so named because their wire elements strike the paper and leave an impression, while character printers focus on printing individual characters rather than graphics or images. Line printers, on the other hand, print an entire line of text at a time.
