ABSTRACT:
A carriage control system for a printer which effects printing by moving the carriage mounted on a print head to reduce the distance on either side of the printing area required for acceleration and deceleration. Various approaches to rapidly and accurately accelerating carriage to a selected constant speed and then decelerating the carriage from the constant speed to a stop are provided. Both open-loop and closed-loop control approaches are utilized.
