Over USB, with OctoPrint on a Raspberry Pi

Every older Prusa printer has a USB port, and connects through OctoPrint on a Raspberry Pi.

OctoPrint
What is OctoPrint? Printers like this support serial printing: another device feeds the printer the print over USB, a few commands at a time. SimplyPrint does that through a plugin for OctoPrint, free serial-printing software that runs on a small computer, like a Raspberry Pi, plugged into your printer with a USB cable.
