LIQUID DISCHARGING APPARATUS AND LIQUID DISCHARGING METHOD

An apparatus includes a mechanism that transports a medium in a transportation direction; nozzle lines each composed of nozzles aligned in the transportation direction, the nozzle lines arranged adjacent to one another in a movement direction orthogonal to the transportation direction; a mechanism that moves the nozzle lines in the movement direction; and a controller for repeating operation of discharging liquid from each nozzle line being moved bi-directionally during outward and homeward movement and operation of transporting the medium in a period between the outward and homeward discharging operation by transportation amount corresponding to nozzle-line length. When a line is printed along the transportation direction using a certain nozzle line in a certain liquid discharging operation, timing of discharging the liquid therefrom is corrected in accordance with duty of printing performed using another, other, or the other nozzle line(s) located downstream of the certain nozzle line in the movement direction.
