Abstract: To save time between printing passes of a unidirectional printer, the print medium is advanced in two phases separated in time by the fast return of the carriage. The print medium advance movements coincide, at least partly, with the periods of acceleration and deceleration which immediately precede and follow a printing pass and during which the carriage is changing from printing speed to return speed or vice versa. If the total print medium advance time exceeds these acceleration and deceleration times, the extra print medium advance occurs at a single end of the carriage movement.
