  • Electronic printing system for imaging thermally sensitive paper
    Patent number: 5327165
    Abstract: An electronic printing system for imaging lines of pixels on thermally sensitive paper is disclosed. The pixels are imaged in accordance with digital data representing whether a particular pixel is to be imaged or not. The system may also operate in a gray scale mode where the optical density of the imaged pixels varies in accordance with digital data. Other features enable the system to image the lines at a high rate of speed and with a lessened power requirement, thus enabling the use of relatively insensitive thermal paper.
