Abstract
A printer includes a light source, a film carrier and a print paper support. A lens turret is mounted between the film carrier and the print paper support and is rotatable about a rotational axis. The lens turret is transversely movable with respect to the path of movement of the print paper whereby an image projected through the film and the lens is transversely movable across the print paper. The lens turret has a plurality of individual lenses for making different sizes of prints. A control system coordinates the longitudinal movement of the print paper and the rotational and transverse movements of the lens turret. A printing method utilizing the printer includes the step of transversely shifting the lens turret whereby the image is shifted transversely on the print paper.
