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.
