Gutenberg's Contribution to Printing in Europe:
Johann Gutenberg developed the first printing press in Europe by 1448, adapting the olive press model and using metal moulds to cast moveable type for the 26 letters of the Roman alphabet. The first book he printed was the Bible — about 180 copies in three years. His press could print 250 sheets per side per hour. Between 1450 and 1550, presses spread across Europe, producing 20 million copies by end of the 15th century and 200 million by the 16th, triggering the print revolution.
