Abstract
A rotatable print disc is mounted on a carrier which traverses along the print line. The disk is moved from each character position to the next by the shortest distance and it is stopped at the time of printing. The carrier is moved from one print position to the next at a speed which is selected depending on the time required for the disk to rotate to the next character. Printing takes place with the carrier moving at one of a number of speeds. The force utilized to drive the hammer to print the characters is varied dependent on which character is being printed. Hammer firing for each character is timed dependent on printing speed and upon the force utilized to drive the hammer.
