Abstract:
1. A liquid discharging apparatus comprising: an upstream side nozzle group; a downstream side nozzle group that is located on a downstream side in a transport direction as compared with the upstream side nozzle group; a transport mechanism that transports a medium in the transport direction to the upstream side nozzle group and to the downstream side nozzle group, and a controller capable of controlling the transport mechanism such that the transport mechanism varies the speed at which the medium is transported in the transport direction, wherein the upstream side nozzle group and the downstream side nozzle group each are formed of a plurality of nozzle columns which eject liquid of a plurality of colors that are arranged in the transport direction, wherein each of the nozzle columns is formed so that a plurality of nozzles that discharge liquid are arranged in a direction that intersects with the transport direction, and wherein the transport speed varies in accordance with the number of nozzle columns used such that only a predetermined number of nozzle columns of the plurality of colors are disposed above the medium at the same time.
