Abstract

In drop-on-demand printers which include a plurality of vertical nozzle arrays 10, such as illustrated in Fig. 1, a number of individually energized nozzles are vertically stacked, the vertical stack printing each scan at one time. Print samples of prior mechanism illustrate some slant in the printing which, while being unobvious at low printing speed, are noticeable in bi-directional printing and at high print speed.
