Abstract
A dot matrix type serial printer wherein a print medium is printed with indicia such as letters, characters, symbols, or the like by selectively driving a number of print elements while moving a print head having the print elements in a direction of a printing line. To enable the simultaneous printing of a number of print lines in different colors, an ink ribbon is provided having a plurality of tracks in the different colors. The print head includes groups of print elements which are arranged such that the respective groups face and are associated with the respective different tracks of the ink ribbon thereby enabling the simultaneous printing of a number of print lines in the different colors by moving the print head. The ink ribbon is adjustable from a first mode wherein the print elements simultaneously print lines of different colors, to a second mode wherein all of the print elements may be associated with a common track of the ink ribbon thereby enabling a simultaneous printing of print lines in a single color.
