Abstract

This article describes an interface for coupling an RGB video color terminal to a color printer using the EIA (Electrical Institute Association) RS343 standard interface. The disclosed interface adapts to video terminals and printers having variable resolutions. (An RGB terminal is a color terminal or monitor that has separate red, green, and blue color input signals as contrasted to a composite video signal which combines the color signals into a single signal requiring subsequent separation before they can be displayed.) Hard copy of the color video display screen is made on color printers, commonly driven via the RS343 interface. The printer must have the capability of printing at the same resolution as the color video display.
