ABSTRACT:
A signal responsive printer selectively deposits drops of liquid ink onto a moving sheet of ordinary paper to form a line of characters. A flexible endless orifice band having a plurality of uniformly spaced orifices traverses a stationary ink source to form ink drops which are chargeable between a corresponding plurality of charging electrodes. Charged ink drops are deflected in direct proportion to their charge between deflecting electrodes to form successive columns of a character dot matrix as the orifice band advances. In order to prevent distortion of a character, an additional deflection compensates for paper motion. Uncharged ink drops deposit on an ink catcher, are drawn into an ink reservoir, and are pumped back to the ink source.
