Article summary

The author of the article built a printer using an e-ink display, the Xteink X3, by implementing the Internet Printing Protocol (IPP) and creating a printer server that runs on the device itself. The printer can receive print jobs from a computer and display the printed pages on the e-ink screen. The author had to work around the device's limited RAM and processing power to achieve this. The resulting printer can print and store pages, which can be browsed on the device.

What commenters say

  • The project is an impressive example of creative problem-solving and repurposing of an e-reader as a printer.
  • The device's limited RAM and processing power make it unsuitable for rendering PDFs directly.
  • The use of Apple Raster and PWG Raster formats is a good alternative to PDF for printing on devices with limited resources.
  • The project's goal of making the e-reader act like paper is a clever and intuitive approach.
  • Some commenters question the purpose of printing to the e-ink display instead of loading documents directly.
  • Others discuss the trade-offs between different e-reader models, such as the X3 and X4, in terms of features like backlighting and USB ports.
