Hangul is still quite finicky to create a movable type with though. Although the basic letters themselves count in the dozens, they can combine not only horizontally but vertically (and even both at the same time), so in practice you would have to create every block for each possible syllable. It's still a lot less than the Chinese scripts, but large enough to make the printing press less practical than the alphabet.
