Duplicating machines were the predecessors of modern document-reproduction technology. They have now been replaced by digital duplicators, scanners , laser printers , and photocopiers , but for many years they were the primary means of reproducing documents for limited-run distribution.
Western printing technology was adopted in all world regions by the end of the 19th century, displacing the manuscript and block printing.

It soon expanded into office supplies and, after licensing key autographic printing patents from Thomas Edison, became the world's largest manufacturer of mimeograph equipment (Albert Dick coined the word "mimeograph").

Some are mechanical and some are chemical. There is naturally some overlap with printing processes and photographic processes, but the challenge of precisely duplicating business letters, forms, contracts, and other paperwork prompted some unique solutions as well. There were many short-lived inventions along the way.
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.
The patent covered the electric pen, used for making the stencil, and the flatbed duplicating press. In 1880, Edison obtained a further patent, US 224,665: "Method of Preparing Autographic Stencils for Printing," which covered the making of stencils using a file plate, a grooved metal plate on which the stencil was placed which perforated the ...
