Good job, but I’m left wanting to know how to build a printer.

  I'd say it's an eco-friendly printer

  Thanks. It's rough around the edges, so PRs are open, and there's a recipe in the repo if you want to build your own apps.

I don't understand the purpose. What am I missing?
The author "prints" to the eink display. Why not load say the pdf directly?

  From the 4th line in the article:
  > But getting stuff onto it was tedious. I had to join its hotspot and open a little upload website in my browser. Yuck.
  Anyway, very creative, I like the idea a lot.

I love the concept, but I wonder why he wasn’t printing to PDF. Can this device not render PDFs?

  I was thinking of this, but rendering PDF takes a lot out of a 400KB RAM'd device. It also needs a ton of things to actually work which the ROM can't hold.
  Kindles have a ton of RAM, this one didn't.

  Probably not. It doesn't appear to have enough ram. I'm not sure the CPU is up to that either.

  if it looks like a paper, it should act like a paper

      It's also not effective against rock

        Funny. But... paper covers rock.

I've been seeing the Xteink a lot lately. Should I get an X3 or an X4? I don't really know why I want it, but I have an eInk addiction, so I just need it.

  I've owned all of them and the answer is the X4 Pro IMO. It has a backlight, which is the only thing I really missed on the others.
- cat-whisperer 1 hour ago
  It's funny that X3 is a successor of X4. Only downside is that X4 has a USB-C port and X3 doesn't

    What about the back light? Are they otherwise identical?

      X3 isn't backlit, but the battery lasts 7 days. So, it's pretty good for me
