Developer turns a programmable Xteink e-ink display into a driverless Mac printer using IPP and Bonjour

The author explains how they made a programmable Xteink X3 e-ink device behave like a printer, letting macOS discover it and send print jobs directly. They implemented IPP support, advertised the device via Bonjour, and handled raster formats so documents could be converted into pixels for the display.

The project shows how open printing standards can make unconventional hardware feel native to mainstream operating systems. It also highlights a broader maker trend: repurposing low-power e-ink devices into flexible, programmable paper interfaces rather than treating them as fixed-purpose gadgets.
