Abstract
Apparatus for printing any line of characters comprises printing wheels on a common shaft, the wheels on the shaft together defining a printing line over a hammer. Each printing wheel is rotated by a respective stepping motor through a respective setting wheel. An aligner bar is inserted into notches in the wheels, prior to printing, to verify the alignment of the characters in printing position. The stepping motors are bi-directional and take the shortest path from a preceding printing position to the next printing position. The pulsing frequency may be ramped to give a higher stepping rate in the intermediate portion of each printing wheel movement.
