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. Johannes Gutenberg invented the printing press around 1440 AD, which started the Printing Revolution. Modeled on the design of existing screw presses, a single Renaissance printing press could produce up to 3,600 pages per workday, compared to forty by hand printing and a few by hand #history #historyseekers #printingpress | History
