If you also want a thing to do typewriting on, later-model word processors (e.g., Smith Corona PWP series) tend to have a feature that auto-types text entered and edited earlier. It'll have the imprinting insofar as the type impacts the paper, but it's not going to have the off-center / over-inked / patchy manual typewriter look. For that you may just want to find a font face that replicates it.

This is what a teletype is: it's a typewriter with a serial connection. You send bytes over the serial cable and it types them.

This is cool, but when viewed up close, laser-printed letters still lack the fuzzy edges and imprinted texture of letters created by typewriter slugs.

Indeed

You want a daisy wheel printer[1] I think.
