Vice recently made a series called "The Dark Side of the 90's." The title theme has a 90's rap sound, but at one point, a dialup modem cuts in. It's even pitch and tempo matched.
I didn't watch this but your description gives me hope that someone, somewhere has noted how dot matrix printers made for great audio samples. Public Enemy comes to mind.
