In wire matrix printers, the nose of the print head must be carefully aligned to traverse the platen parallel to its surface in both the horizontal and vertical directions. That is, the plane of the ends of the wires of the wire matrix printer must be parallel to the plane of the surface of the platen. Traverse adjustments are made by positioning the ends of the platen in or out and/or by causing the print head to follow the surface of the platen with a roller. This does not take account of any axial rotation of the platen which would cause the plane of the platen surface to intersect the plane of the wire ends of the wire matrix printer. A simple solution is shown in the drawings which permit rotational adjustment of the platen about its longitudinal axis in a simple and reliable way. In Fig.
