Abstract
A serial impact printer has two printing modes, one being a formed-character mode and the other a dot matrix mode. A plurality of dot matrix wires are disposed behind a character carrying member having characters on fingers. One of the wires impacts a selected finger in the formed-character mode. In the dot matrix mode, however, printing is performed by directly contacting a paper with selected ones of said dot matrix wires.
