Matrix printer with optimum printing velocity

摘要

A serial printer is provided which moves the printhead at optimum velocity with respect to the document being printed so as to achieve maximum throughput. Prior to the printing of each line of alphanumeric characters, the printer contains means for determining the length of said line. In response to said determined line length, drive means move the printhead across the medium at a selected velocity which is based upon the determined line length. The present expedient is particularly applicable to matrix printers wherein the selected velocity is constant during the actual printing of the line.
