Answer: The printing press made books easier and cheaper to produce, which increased the number of books, and lowered the cost of books so that more people could learn to read and get more reading materials.
This idea is really cool because there are books, and they make it cheap, and people or children can learn with these ideas of books, so it can entertain them, and learn too. Reading materials could mean how they made it, or basically the story of what materials its using.
This was a good plan that printing press influenced this.
Hope it helps :)
