The author transformed an Xteink X3 e-ink display into a network-accessible printer by implementing the Internet Printing Protocol (IPP) server, enabling macOS to print directly to it via Bonjour discovery. The custom service, named 'penguin,' advertises printer capabilities like 300 dpi monochrome output and accepts Apple raster and PWG raster document formats.
