Abstract
A type element (22) is driven across a sheet of paper (24) and a hammer is driven at desired space positions for printing without stopping the type element (22). A length of time required for the type element (22) to select a new character is computed, and a type element drive speed for a next space is computed as a function of the selection time and the present drive speed so that the type element (22) will reach the next space in a length of time substantially equal to the selection time, thereby compensating for acceleration or deceleration of the type element (22).
