Abstract

The throughput of a serial printer is improved. A inkjet printer 100 has a print unit that prints on a print medium; a first transportation unit that conveys the print medium in the primary scanning direction; a second transportation unit that conveys the print unit in a secondary scanning direction substantially perpendicular to the primary scanning direction; and a control unit that controls the transportation operations of the first and second transportation units, so that the time required to move the print unit from the stop-printing position where the print unit finishes printing one print area to the start-printing position where transportation for printing the next print area starts is shortest. The control unit also determines a transportation range that may include the print unit going beyond the stop-printing position when the print unit prints the one print area.

Dependent claims

A printing device, comprising:

a print unit that prints on a print medium;
a first transportation unit that conveys the print medium in a primary scanning direction;
a second transportation unit that conveys the print unit in a secondary scanning direction substantially perpendicular to the primary scanning direction;
and
a control unit that controls the transportation operations of the first transportation unit and second transportation unit, the control unit being further configured such that
when controlling the second transportation unit and conveying the print unit from a stop-printing position where the print unit finishes printing one print area to a start-printing position where printing a next print area starts, the control unit determines either or both a standby position where the print unit stops after printing the one print area and a transportation range of the print unit, based on the distance needed to accelerate transportation of the second transportation unit.

3 more elements

A printing method, comprising:

determining either or both a standby position where a print unit stops after printing one print area and a transportation range of the print unit, based on the distance needed to accelerate the print unit;
and
when scanning and printing the one print area on a print medium using the print unit, conveying the print unit from a stop-printing position where printing the one print area ends to a start-printing position where printing a next print area begins.
