A printing press is a mechanical device for applying pressure to an inked surface resting upon a medium, thereby transferring an image. The mechanical systems involved were first assembled in Germany by the goldsmith Johannes Gutenberg around 1440, based on existing screw-presses used to press cloth, grapes etc., and possibly to print woodcuts, which were printed in Europe before Gutenberg. Although both woodblock printing and movable type printing press technologies were already developed first in China, and Korea in East Asia several hundred years earlier, Gutenberg was the first in Western Europe to develop a printing press.
