D&D is not medieval. It's anachronistic (because fictional).
Having printing press or something equivalent existed does not necessarily mean high literacy rate. I did see claims that it took more then 200 years after the printing press for the literacy rate. to go over 50%

As a side note I been involved with D&D 1st and tend to join groups that are old school, and have worlds heavily based off medieval europe
