Abstract
A color video printer has a liquid crystal body acting as a shutter extending across a color printing paper. The liquid crystal body includes a first shutter array for a first color, a second shutter array for a second color, and a third shutter array for a third color, and an electrical arrangement for supplying first, second, and third color signals to the respective first, second, and third shutter arrays. Relative motion between the liquid crystal body and the color printing paper is provided in a direction to cause the liquid crystal body to scan the paper.
