who invented the printing press and what year
circa 1439 Johannes Gutenberg
title: Printing press text: Printing press A printing press is a 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. Johannes Gutenberg, a goldsmith by profession, developed, circa 1439, a printing system by adapting existing title: Printing press text: of cylinders. Both elements were for the first time successfully implemented by the German printer Friedrich Koenig in a series of press designs devised between 1802 and 1818. Having moved to London in 1804, Koenig soon met Thomas Bensley and secured financial support for his project in 1807. Patented in 1810, Koenig had designed a steam press "much like a hand press connected to a steam engine." The first production trial of this model occurred in April 1811. He produced his machine with assistance from German engineer Andreas Friedrich Bauer. Koenig and Bauer sold two of their first models to title: Printing press text: antiquity in Gutenberg's time and was used for a wide range of tasks. Introduced in the 1st century AD by the Romans, it was commonly employed in agricultural production for pressing wine grapes and (olive) oil fruit, both of which formed an integral part of the mediterranean and medieval diet. The device was also used from very early on in urban contexts as a cloth press for printing patterns. Gutenberg may have also been inspired by the paper presses which had spread through the German lands since the late 14th century and which worked on the same mechanical principles.

He moved to London in 1804, and met Thomas Bensley; he secured financial support for his project in 1807. With a patent in 1810, Koenig designed a steam press "much like a hand press connected to a steam engine." The first production trial of this model occurred in April 1811. A printing press is a mechanical device for applying pressure to an inked surface resting upon a medium (such as paper or cloth), thereby transferring an image. The systems involved were first assembled in title: Printing text: Printing Printing is a process for reproducing text and images using a master form or template. The earliest non-paper products involving printing include cylinder seals and objects such as the Cyrus Cylinder and the Cylinders of Nabonidus. The earliest known form of printing as applied to paper was woodblock printing, which appeared in China before 220 AD. Later developments in printing technology include the movable type invented by Bi Sheng around 1040 AD and the printing press invented by Johannes Gutenberg in the 15th century. The technology of printing played a key role in the development of the Renaissance and
