Abstract
A print wheel is rotatably mounted on a carrier driven by a stepper motor to traverse the print line of a document. The wheel contains two or more arrays of characters with preferred characters most commonly used in each array and a number of lesser-used characters divided between the arrays. The print wheel normally makes one revolution for each two or more print positions and if a compare is made in each array the stepper motor advances the carrier at constant speed. Should a compare not be found or the character desired be too close to a previous character for the print hammer to settle out, the stepper motor is stopped for that position until a compare is made in some following array.
