A dot matrix printer is a computer printer that uses an arrangement of pins or wires from a matrix to form printed characters. A signal from an electromagnet causes the hammer to hit a pin strikes an inked-up ribbon making a dot on the paper. The pins are activated in different combinations so that each character is made up of several vertical dot patterns.Sunday 4 September 2011
