Decent article. I owned a 5-channel teleprinter for a while in my youth (they were junk at the time, while a real ASR-33 would be worth something). I had to generate baudot code by bit-banging an I/O pin in software because the UARTs even then didn't support 5-bit characters. It smelled of oil. No electronics, only lots of mechanical gubbins and a couple of electromagnets. The key point of the article is that teleprinters pre-date computers by decades; when people built the first computers they stole a teleprinter from down the hall to interact with it; then teleprinters further evolved to meet the computer use-case (transition from baudot to ASCII).
