CATHODE RAY TUBE PRINTING APPARATUS AND METHOD ABSTRACT Apparatus is described for producing hard copy prints of images displayed on a raster-scanned CRT terminal. A row of light-fibres are attached to a preselected scan line of the CRT. The other ends of the row of light fibres are located along the surface of a print roller on which light sensitive paper is supported. A light pattern pro- duced as a result of an image scan along the preselected scan line is transmitted by the light fibres to the paper which is exposed to form a latent image of the light pattern in a print row on the paper. In order to print a complete image, the paper is drawn past the print row and exposed successively to each raster scan row of the image to be printed. The exposed paper is then passed through a developing station where the latent image is developed by heat. Two modes of operation are described. In one mode the image display is interrupted during the print cycle, in the other mode both display and printing are performed concurrently. UK9-78-018
