Increased printing speeds may be achieved with ball-element typewriters by varying selection shaft speed in accordance with the character to be printed or, more particularly, the distance of the character position on the element from the home position. For example, if five rotate selections are provided for each direction, the normal speed might be used for only selections at the most remote position. By increasing the speed for the shorter distance selections, it is possible to speed up printing without increasing the mechanical stresses occurring during selection beyond those that occur for the most remote selection at normal speed.
