when was the printing press first invented
By 1440 Gutenberg had established the basics of his printing press including the use of a mobile, reusable set of type, and within ten years he had constructed a working prototype of the press. In 1454 Gutenberg put his press to commercial use, producing thousands of indulgences for the Church. The following year he printed his famous 42-line Bible, the first book printed on a moveable type press in the West.
