Who invented the printing press with medal movable type in 1455 AD?

The world's first known movable-type system for printing was created in China around 1040 AD, by Bi Sheng, during the Song Dynasty. Next, a metal movable-type system for printing was created in Korea during the Goryeo Dynasty, at around 1230. Then, around 1450, Johannes Gutenberg introduced what is generally regarded as an independent invention of movable type in Europe. Today, most movable-type printing ultimately is based on Gutenberg's movable-type printing, which is often thought of as the most important invention of the second millennium.
