Abstract
Interface and control apparatus for translating color video signals from a video terminal or the like into control signals useful by a dot matrix impact printer/plotter for producing a hard copy image. The color video signals are digitized and used to address a programmed read only memory having a plurality of addressable locations. The memory stores a table for translating color video signals defining a three-dot video pixel into control signals enabling a printer/plotter apparatus to produce a hard copy image of a substantially equivalent four-dot printer/plotter pixel.
