Abstract

An inkjet drop ejection apparatus includes a chamber with a plurality of nozzles grouped in pairs, and a plurality of actuators. Each of the plurality of actuators is associated with a pair of nozzles and operable to cause ink to be ejected from either one of the pair of associated nozzles. Each of the plurality of the actuators is provided midway between its associated pair of nozzles, adapted to simultaneously move towards one nozzle of the pair and away from the other nozzle of the pair, whereby ejection of ink through the nozzle towards which the actuator is moving is effected.
