Реферат: ABSTRACT OF THE DISCLOSURE A dot matrix printing head nozzle structure and method of manufacturing such structure wherein a plurality of holes are formed in a block of plastic material using permanent and removable inserts. The holes are provided for receiving printing elements which are arranged to be as near perpendicular to the record medium as possible consistent with the size of the armature needed to drive the printing elements. The removable insert serves the additional function of providing an antiwicking region along the inserted wires to control undesirable ink flow along the wires when the nozzle is used for printing through an inked ribbon.
