Abstract: A serial impact printer capable of performing multicolor printing at high speed. In this printer an inked ribbon divided into multiple colored bands each along the longitudinal direction thereof is arranged to extend and move in a direction intersecting the print line. A print head assembly is provided with print wire units arranged along the print line, as many in number as the number of the colored bands. Each of the print wire units comprises a plurality of print wires and is disposed in opposition to each of the colored bands respectively.In this arrangement and method multicolored impact serial printing can be performed, just as in conventional monocolor impact printing, without any color change motion of the multicolor inked ribbon or of the print head.
