The Chinese invented moveable type, and Johann Gutenberg, a monk from Germany, invented the printing press which used the Chinese's method of moveable type, just in a simplified and simpler way.
It is Bi Sheng. He invented the moveable-type printer in mid 12th century.
The phrase "what moveable type was used for" can be summarized as "the purpose of moveable type." Moveable type was primarily used for printing texts, enabling the mass production of written material and facilitating the spread of information, literature, and ideas during the Renaissance and beyond.
