Abstract

A high speed matrix printer has print hammers spreading across the entire width of a print line for striking dots, which were embossed on a metal band or metal fingers, which in turn strike an inked ribbon for producing characters on a printing medium. The dots are arranged on a single level on the band, and the paper steps a single picture element (pel) after a single line of dots is completed. For 5 x 7 matrix character printing, seven paper increments are required to complete a print line (character line). The printing speed and resolution are limited due to the number of paper increments.
