Abstract: There is disclosed herein printer control logic for controlling a matrix printer. The control logic includes an interruptable microprocessor, together with associated memory. Additionally the control logic includes a programmable timer which provides a signal a determined time after being programmed. The control logic responds to print emitter signals manifesting an incremental movement of the print head by interrupting the microprocessor. The microprocessor then programs the timer to provide signals after a programmed delay time to again interrupt the microprocessor. The microprocessor then provides signals causing the operation of the print elements on print head.

Apparatus and method for controlling the velocity of a moveable member
Peter P. Aiena
- 10 Nov 1977
TL;DR: In this article, an apparatus and method for controlling the velocity of a moving member like, for example, a print head carrier is presented. Butler et al. used a processor to control the velocity with respect to a desired nominal velocity and for performing additional operations such as grouping of characters to be printed, firing print actuators, etc.

- 28 Oct 1976
TL;DR: In this paper, the problem of correct alignment of symbols on two neighboring lines in both directions is solved by delaying the time of activation of the drive to forward motion relative to backward motion, or vice-versa, by an amount which corresponds to the flight time of the printing wires.
