More Information
Summary:Each ink droplet printed on a recording surface, which has relative movement along a first axis with respect to ink droplet producing means, forms part of a character, and may be disposed in any granular position in a second direction, which is substantially orthogonal to the first axis, relative to a single predetermined position, which is the gutter stream position. Information concerning the location on the recording surface of each printed droplet relative to the single predetermined position in the second direction and to the prior printed droplet or a margin along the first axis is stored in a read-only storage (ROS). The information concerning the location of the droplet in the second direction is a voltage applied to charging means with the magnitude of the voltage in conjunction with any induction created by prior adjacent droplets of the ink stream determining the deflection of the droplet. Synchronization of the relative movement along the first axis with respect to the generation of the droplets is obtained whenever there is a predetermined spacing between the printed droplets along the first axis after it has been determined that synchronizaton is required.
