Abstract
A multi-ink jet printer contains n nozzle orifices, which are aligned in one or two nozzle orifice arrays with its axis (or axes) substantially parallel to the relative print direction. All print droplets generated from nozzle orifices are individually charged and are deflected under a common deflection electric field substantially perpendicular to the relative print direction. All nozzle orifices may be individual single jets, or may be formed on an orifice plate sharing the same ink system, same stimulation, same deflection electrodes and the same ink collector. Using the interlacing schemes described in this teaching, the said multi-ink jet printer can print marks, characters, or graphics on receiving medium at n times the print speed of a single jet printer and still maintaining excellent print quality.
