In the 15th century, a technological innovation changed the world forever. This is the story of the printing press, a device that revolutionized communication and knowledge.br ohannes Gutenberg, a German inventor, is credited with perfecting the printing press around 1440. His invention combined movable type with mechanical printing, making it possible to mass-produce books and documents for the first time.br The printing press used movable metal type, ink, and a screw press. Individual letters could be arranged to form text, inked, and pressed onto paper, allowing for quick and efficient printing of multiple copies.br One of the first major projects produced with Gutenberg’s press was the Gutenberg Bible. Printed in the 1450s, it demonstrated the press’s ability to produce high-quality, uniform copies, revolutionizing the spread of information.br .br .br .
