Abstract
An ink jet cartridge includes two adjacent jet plates, each jet plate having an array of equally spaced nozzles. A small gap exists between the first and second jet plates which is devoid of any jet nozzles. The absence of nozzles in the gap is compensated for by the inkjet printer system such that the two jet plates function as a single nozzle array.
