Calling Gutenberg a James Watt to Chinese printing press designs is... questionable. Afaik he was not aware of Chinese/Korean designs that he could have improved upon. Also, the Chinese designs arguably weren't presses, since they rubbed paper against a type - the screw was one of the many important innovations by Gutenberg. The article would benefit from focusing less on the "race" between Europe and China (which arguably wasn't one, but two largely separate developments) and more on the technology.
It was because, Gutenberg did not invent movable type. That was already in use in Europe. A high chance that technology came from Asia. Hence Gutenberg took an exiting technology and improved it. Gutenberg did not invent the screw press. Almost identical presses were already used in paper making. This was about combining a variety of technologies into one better system.
