The Prusa mini has an ethernet port, so people assumed that you could hook it up to your LAN and print over the network.
As far as I can tell, that doesn't work yet, and the Prusa website [1] says:
> Full control of your printer will be added in future releases
Edit: It looks like remote printing was released in a Firmware update in Nov 2022 [2] and the documentation website wasn't updated yet.
