Actually, I am covering that in the next article on printing comming soon which is on review. It is accessible on Substack but you need to be a subscriber to to see the part where I discuss character sets: https://erikexamines.substack.com/p/why-was-western-printing-superior

I focus more on Hangul, the Korean characters there because it has often been suggested as an example of an Asian character set which could have been used for Western style printing. Printing was quite advanced in Korea.

However, this article is more focused on the technical aspects. Regardless of alphabet or glyphs available the far East lacked many of the prerequisites for developing the kind of system Gutenberg made. A printing press inventor in Asia would have had to invent both oil paint and a screwpress for instance, while Gutenberg just had to adapt existing technology to serve printing.
