GoKawiilDeveloper turns Xteink X3 e-reader into a Wi-Fi printer using IPP
A hobbyist bought the Xteink X3 e-ink display for its programmability and, frustrated by having to upload files through a clunky hotspot-based web page, decided to make it work like an actual printer. By implementing the Internet Printing Protocol and advertising the device as an AirPrint-compatible printer named 'penguin' via Bonjour, they enabled sending documents directly from a MacBook's Print dialog to the e-ink screen.
