Printing press is a mechanical device for applying pressure to an inked surface resting upon a print medium (such as paper or cloth), thereby transferring the ink. It marked a dramatic improvement on earlier printing methods in which the cloth, paper or other medium was brushed or rubbed repeatedly to achieve the transfer of ink, and accelerated the process. Typically used for texts, the invention and global spread of the printing press was one of the most influential events in the second millennium. — Wikipedia
Printer is a machine that uses ink to either print digital documents, or in some cases photo copy physical documents. — Wikipedia
Offset printing is a common printing technique in which the inked image is transferred (or “offset”) from a plate to a rubber blanket and then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water, the offset technique employs a flat (planographic) image carrier. Ink rollers transfer ink to the image areas of the image carrier, while a water roller applies a water-based film to the non-image areas.
The modern “web” process feeds a large reel of paper through a large press machine in several parts, typically for several meters, which then prints continuously as the paper is fed through. — Wikipedia
