Abstract: NON IMPACT DISPLAY SCREEN OUTPUT PRINTER A convenient hard copy output of a cathode ray tube (CRT) screen display is provided by a thermal printer which prints a line of dots equal in number to the number of dots in one raster scan on the CRT screen by printing the information in one such raster scan during each refresh cycle of the screen until the entire screen content has been reproduced. Use of one line during each refresh cycle enables the reproduction of the screen content by gating the serial data from the display control circuitry without the need for a separate character generator or the related circuitry and also accommodates the use of an interlaced raster.

Abstract: THERMAL PRINTER WRITE HEAD ASSEMBLY A non-impact thermal printer is formed using a pivoted stiffner-frame on which is mounted a printed circuit card-print head assembly. The card is slotted with the print heads mounted at the distal ends of the cantilevered portions to enable close compliance between print head read/write units and the print media through the torsional resilience of the circuit card cantilevered portions. Compact, simple structure is provided by having the printer control circuitry mounted on the same printed circuit card. RO977-021

Abstract: DISPLAY-ATTRIBUTE CONTROL FOR AN ALPHANUMERIC COLOR DISPLAY An alphanumeric color display terminal translates an input set of monochrome display attributes into both a set of color display attributes and an overlapping output set of monochrome display attributes, and controls the color display in accordance with the color and the output monochrome attributes. Translation and control are performed with a ROM and control logic acting upon video signals.

Abstract: A line printer attachment for converting a display screen copier printer to a line printer. The last or extra line of the display is used as the line print buffer. An initiate print signal is generated upon detecting that the last or extra line is to be scanned. The initiate print signal is used to blank or inhibit the serial video data from the display screen and to enable the printer. The serial video data is constantly sent to the printer attachment but is ignored until the printer is enabled. With the printer enabled, printing takes place using the line print buffer data which has been serialized as serial video data. The print buffer data remains unchanged during the entire printing of the line where the printing is done in series of horizontal lines to complete the printing of a line At the end of each horizontal line of print a vertical screen retrace occurs and the display screen is swept where again the last or extra line is detected and another initiate print signal is generated. The next horizontal line of the series of horizontal lines fox completing a line of print is printed and the operation repeats until an entire line of printing is completed.
