ABSTRACT:
A matrix printer comprising a fanned arrangement of printing wires. Near their bearing points the printing wires are guided through openings in tag portions bent out of the plane of a strip-shaped porous member containing a lubricant. Lubricant is thus applied to the printing wires by contact between the printing wires and the edges of the openings adjacent their bearing points. The described method of lubrication results in a substantial prolongation of the service life of the printing wires as well as of the bearings.
