Abstract: A control system for a bidirectional printer having a print head carriage movable at different speeds on different printing lines employs a microcomputer which generates a desired velocity profile for the carriage motion. This desired velocity profile is continuously compared with the actual velocity and the error voltage generated is used to control pulse width modulator circuitry which supplies driving power to carriage drive motor.

Abstract: In a control system for a bidirectional printer capable of printing at different speeds on different lines and in which the actual velocity of the print carriage is compared with a desired velocity profile to generate an error count, the error count is measured and averaged out for each direction and speed of carriage movement to compensate for the effect of changes in the printer system dynamics such as aging, wear, debris buildup, etc.
