Abstract
Abstract A method of printing mosaic characters which may be used in telegraphic printers, wherein a column of styli are employed twice at two different vertical locations to print a single column or partial column of dots. The number of individual styli and the actuators therefor are thus halved over those required in prior art stylus heads. The complexity and size of the styli and actuators make this a substantial advantage.
