Abstract
A high quality, variable font, matrix printer employs a precise carriage position control system that precisely determines the position of the carriage at discrete positions in combination with a variable time delay in the matrix element firing circuit to permit each printed matrix element to be positioned at one of the various carriage positions, or between discrete carriage positions, thereby permitting essentially continuous horizontal lines and high quality characters of various fonts and sizes to be printed. In such a system, the positions of the elements forming the particular characters to be printed are defined by stored information representative of carriage position and time delay. Essentially continuous vertical lines are generated by precisely controlling the paper feed to permit matrix element overlap, and characters larger than the printing matrix may be generated utilizing multiple printing passes with an appropriate paper advance.
