A droplet ejection control apparatus includes a head unit in which a plurality of vertically arranged nozzle groups in which a plurality of nozzles for ejecting droplets onto a predetermined target of ejection are arranged in the vertical direction; and a control unit for controlling ejection of the droplets from the nozzles. The control unit controls ejection of the droplets for vertically adjacent nozzle groups such that an amount of ejection from at least one nozzle of a vertically upper nozzle group at a joint portion between nozzle groups is reduced, and an amount of ejection from at least one nozzle at the joint portion between the nozzle groups of a vertically lower nozzle group is increased.
