ABSTRACT: A novel electronic printing system for operating both a linear-raster electro-optical display device and a linear-raster type printer, which system is capable of integrating alphanumeric and/or graphics information and gray-scale or picture information, all on a single data base from which one may either (or both) print the data out on the printer as images, or display the data on the device as images. The system includes look-up tables storing respective first and second subsets of a set of substan- tially disjoint multiple-bit binary index numbers. Each of the numbers of the first subset represent information corresponding to a respective gray-scale density level ren- dered as a respective matrix of points forming a corresponding gray-scale cell to be pointed by the printer. Each of the numbers of the second subset represent infor- mation corresponding to a unique shape of an edge rendered as a respective matrix of points to be printed by the printer. Means are provided for translating an image of the infor- mation to be printed and/or displayed into an array of index numbers selected from the subsets, and for storing that array. Conversion means ace provided for converting at least a major portion of the array into electrical signals for forming a display of substantially the desired image on the display device and for converting at least a major portion of the array into electrical signals for forming matrices for assemblage as the image in printed form on the printer.
