Over 500 years ago, in 1445, Johannes Gensfleisch the Young, also called Gutenberg, revolutionized the printing press. Gutenberg invented not the printing press itself as is often wrongly assumed, but a new process of printing.
This new process utilized many single metallic letters which could be joined together in lines and thus made it possible to print extensive works quickly and cheaply.

from the Gutenberg Bible
The printing press was immensely important for the dissemination of the Reformation ideas of Luther and his fellow thinkers. Only Gutenberg's printing system enabled the targeted and quick distribution of texts that were printed in large numbers.
