I have an alternate proposal:

• buy a ball-head typewriter. Very satisfying to write on. And you get to see your text on paper right away.

• modify it to have a USB interface

• setup a Pi Pico to log all text entered on the typewrite

• when you connect the Pi Pico to your PC it replays the entered text at high speed.

No need for the trouble with USB / Pi. You can use an app on your phone to OCR the paper.

True. But that results in elevated error rates.
