ABSTRACT:
A matrix printer comprising a printing head which can be moved to and from along a record carrier in a direction parallel to a printing line direction. The printing head is provided with straight recording pins which are arranged to be mutually parallel at equal distances from each other. The printing ends of the recording pins are situated in one line parallel to the printing line direction. Between the printing head and the record carrier an ink ribbon is arranged which is intermittently displaced, together with the record carrier, in a direction transverse to the movement direction of the printing head. The ink ribbon wear and reduction of the coloring agent are thus spread over the full width of the ink ribbon.
