High speed printer

TL;DR: In this article, double and triple sized characters are printed through a segmented technique in which segments of the double-and triple-sized characters are stored within readable memories (ROMS).

TL;DR: In this article, a printer system has local control for dynamically positioning a print head relative to a print medium utilizing positioning and print data signal inputs, including a control unit for receiving and storing data inputs, the control unit including circuit means responsive to the positioning data for arranging and outputing the stored print data to the print head, control circuitry connected to said control unit and head positioning apparatus employing a movable print medium connected to the control circuitry for positioning the head in relationship to the web in response to a control circuitry so that the head is thereby dynamically controlled by the respective data signal

TL;DR: In this article, an all-electronic control system for a high-speed dot matrix printer, using a permutation code input signal comprising individual code words each including a fixed number of data pulses preceded by a start pulse, is presented.

TL;DR: In this article, a method and apparatus for controlling the print rate of a column-sequential dot matrix printer actuated by an input signal comprising a sequence of code words occurring at a given maximum input rate, a print head and a print-head drive operating at a speed determined by the frequency of a print rate timing signal, and a multi-stage FIFO input storage register is presented.

TL;DR: In this paper, the authors describe an electromagnetically-operated selective printing machine with a number of drive hammers, each having a width corresponding to four characters, and each hammer being moved leftward three steps from its initial rightward position.
