a printing device, commonly used in
offices, in which a waxed paper stencil
bearing text that has been
cut by a typewriter, or text or a drawing done by
hand with a stylus, is fastened to a drum which is inked on the inside so that the ink penetrates the
cut areas and is deposited on a new
sheet of paper with each revolution of the drum.
