ABSTRACT:
A plurality of ink droplet issuance units are provided for emitting plural streams of ink droplets toward a record receiving paper. The ink droplets in the respective streams are charged by a bi-valued signal through the use of a plurality of charging means in accordance with print information. The ink droplets charged by one value of the bi-valued signal are deflected as they pass through a deflection means and deposited on the record receiving paper. The ink droplets charged by the other value of the bi-valued signal are directed to a beam gutter and not deposited on the record receiving paper. In this way, one column of a dot matrix pattern is printed at a time utilizing plural streams of ink droplets.
