High-speed printer with drift compensated cable for carriage

TLDR
In this paper, a high speed printer is coupled to a servo controlled driving motor having intermittent motion, and the motor drives a helically grooved pulley which has attached to it left and right cable segments of equal length.
Abstract
A high speed printer in which the carriage carrying a printing wheel is coupled to a servo controlled driving motor having intermittent motion. The motor drives a helically grooved pulley which has attached to it left and right cable segments of equal length. The other ends of the cable segments are attached to the movable carriage. During movement of the carriage the total length of each cable segment remains constant and equal and provides protection against temporary mechanical drift.

Microprocessor - controlled positioning system

TL;DR: In this paper, the authors present a positioning system for a line printer using dc servomotors for driving a forms feed mechanism in increments of one or more line spaces at a time, including a microprocessor and a position counter that counts either 1/4 or 1 degree displacement pulses generated by a motion indicating means.
