Matrix printer

摘要

Matrix printers of this kind usually have a print platen (2) with an arched surface which lies opposite a print needle array (24) of a plurality, such as for example 5 to 12, printing wires (8) lying one on top of the other. In order to avoid disadvantages in the desired image as a result of the arching of the print platen (2), it is proposed that all the printing wires (8) with their printing face (8c) in its zero position before the electromagnetic coils (13) are energised are at the same distance (27) from the arched surface (2b) of the print platen (2). <IMAGE>
