Iron letter copying press, late 19th century, Germany. In 1780 James Watt obtained a patent for letter copying presses, which James Watt & Co. produced beginning in that year. Letter copying presses were used by the early 1780s by the likes of Benjamin Franklin, George Washington, Henry Cavendish, and Thomas Jefferson. [4]
A 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.

With the advent of the Industrial Revolution and industrial mechanisation, inking was carried out by rollers that passed over the face of the type, then moved out of the way onto an ink plate to pick up a fresh film of ink for the next sheet.

The stencil-copy method meant that only one copy had to be read, as all copies were mechanically identical. Gestetner had therefore revolutionised the office copying process. Gestetner developed his invention, with the stencil eventually being placed on a screen wrapped around a pair of revolving drums, onto which ink was placed.
