Abstract

Impulse ink jet apparatus has a plurality of side-by-side chambers extending along a line that is slanted with respect to a direction of scanning relative to a recording medium. Each of the chambers includes a plurality of orifices that are arranged along a line extending substantially transverse to the scanning direction and a transducer for ejecting a plurality of droplets from the orifices of each chamber. The orifices are formed upon an orifice plate such that the distance between the centers of adjacent orifices associated with a single chamber are separated by a predetermined distance greater than the center distance required for drop placement on the recording medium.
