LIQUID DISCHARGING APPARATUS AND LIQUID DISCHARGING METHOD

PROBLEM TO BE SOLVED: To reduce a positional deviation of a connecting part of a ruled line by a method other than suction. SOLUTION: The liquid discharging apparatus includes a transporting mechanism which transports a medium in a transportation direction, a plurality of nozzle lines each of which is composed of a plurality of nozzles aligned in the transportation direction and which are arranged side by side in a movement direction that intersects the transportation direction, a moving mechanism which moves a plurality of nozzle lines in the movement direction, and a controller which changes a moving speed of a plurality of nozzle lines by the moving mechanism according to a printing duty whereby printing is performed by other nozzle lines of the downstream side in the movement direction from a certain nozzle line at the time of a liquid discharge operation when the ruled line is printed in the case of printing the ruled line along the transportation direction by the certain nozzle line. The controller repeatedly executes a liquid discharge operation of discharging the liquid from each nozzle line during movement in both outward and homeward directions while moving a plurality of nozzle lines outward and homeward in the movement direction by the moving mechanism, and a transportation operation of transporting the medium in the transportation direction by a transportation amount of a length of the nozzle line by the transporting mechanism in a period between the outward and homeward liquid discharge operations.
