PROBLEM TO BE SOLVED: To overcome the problem of optimizing the total print time of a unidirectional mode printer. SOLUTION: In the method for operating a printer in unidirectional mode, at the end of a printing pass, a printing carriage is decelerated from its printing speed and accelerated in the opposite direction to a return speed in a first phase, returned toward its start end at the return speed in a second phase, decelerated to zero speed and accelerated in the printing direction to its printing speed in a third phase, and during the above period an appropriate advance occurs in the print medium axis so that the next printing pass can start, and that print medium advance movements are undertaken in both the first and second phases.
