Abstract
An inkjet printer includes nozzle rows aligned along a printing direction along which printing on a print medium is executed, and a controller configured to control ejection of the ink droplets from the nozzle rows. The nozzle rows include a pair of an upstream nozzle row and a downstream nozzle row. The upstream nozzle row is positioned just upstream from the downstream nozzle row along the printing direction. The controller controls ejection of the ink droplets from the upstream nozzle row and the downstream nozzle row so that propulsive forces applied to ink droplets ejected from the downstream nozzle row are made larger, based on image data associated with the upstream nozzle row, than propulsive forces applied to ink droplets ejected from the upstream nozzle row. The inkjet printer can restrict degradation of print quality by landing the ink droplets ejected from the downstream nozzle at their target positions.
