Abstract

A velocity of a motor which selects a type element of a type head or a motor which drives a carrier carrying the type head in a printer is controlled in accordance with a positional error which represent a distance from a present position to a target print position of the type head or the carrier. When the motor is stopped at a desired position, it is appropriately damped.
