An improved matrix printer is described employing a high order, single track incremental position encoder to provide a plurality of electrical reference signals representative of predetermined print positions along a platen and for locating matrix columns at the predetermined print positions. An electronic circuit is provided for varying the predetermined print positions at which the matrix columns can be located.

Printer having variable character density

Maximizing the printing rate of an electronic printer by causing it to print data characters at a relatively constant rate despite variations in the pattern of the incoming data. The number of characters in an incoming data pattern to be printed substantially simultaneously is monitored and the printing rate controlled within certain limits to provide a maximum printing rate consistent with the power and mechanical limits of the printer design.
