You could get close to inkjets and early laser printers with Signum! on the ST and 24-pin dot matrix printer. It used custom bitmapped fonts and very fine control of the pins to generate amazing output.

It was very slow in the highest quality setting, but most people couldn't tell it apart from much more expensive solutions. It also had an astounding equation editor which made it great for STEM work.

"too closely" hardly qualifies IMO as "indistinguishable".

Maybe I'm a printer nerd, but I could generally tell the printer manufacturer from its output in the time they were popular.

Not to mention that back then, I don't think any consumer-grade dot matrix used single sheet paper like a typewriter would. The tractor punched-hole bars on the side after removal would give it away; even that fancy super-perforated stuff.
