ABSTRACT:
A wire matrix print head movable along a print line has a pair of guides containing print wires arranged in two parallel columns. Horizontally movable sloped platforms are provided for moving the guides vertically relative to each other so as to change the alignment of the wires in one guide with those in the other guide, thereby changing high speed mode of printing to high quality mode, and vice-versa.
