ABSTRACT:
Through-put of a printer is increased by optimizing the print head's movement between print lines. Optimization is performed on a time basis rather than a distance basis. A determination is made as to whether it is quicker to position the print head at the left or right end position of the next print line. The calculations account for current print head position, the relative end positions of the next print line, the length of the next print line, current print head speed, the various acceleration and deceleration times and the turn-around settling time for the print head.
