What yeard did inventor Johannes Gutenberg come up with the printing press?”
Johannes Gutenberg invented the mechanical printing press in 1439. Among the specific contributions to printing that are attributed to Gutenberg are the invention of a process for mass-producing movable type, the use of oil-based ink, and the use of a wooden printing press similar to the screw olive and wine presses of the period. His truly epochal invention was the combination of these elements into a practical system.
