Outstanding! This is so...correct.

We finally have PADDs from Star Trek!

This is amazing!!! It just makes sense. And its just how you would want to use a e reader.

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.

This is a fantastic idea!

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

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

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

Very cool. I'll be updating to this fork

>penguin would shrink the result to fit its screen. >I declared A5 and Letter paper, media type stationery, and an output bin called face-up. You can (and should!) define exact dimensions of your screen in `media-size-supported`. It will probably be a non-standard IPP name, that's why you should define that in `media-supported` as `om_NNNmmxYYYmm` or `oe_NNNinxYYYin` That way you don't need to scale the incoming data, the PC will format it exactly to the dimensions of the screen. Both PWG Raster and Apple Raster support 1-bit-per-pixel mode (instead of 8-bit-per-pixel you use), that's why the input could be 8 times less in size. Use `print-color-mode-{supported,default}=bi-level` instead of `monochrome` for that. And also tune `urf-supported`'s `W` option, use `W1` for this case. The screen/dithering could be ass in 1-bit mode, see https://github.com/OpenPrinting/libcupsfilters/pull/160 where I added more dithering options (Linux-only though, Apple seems to abandon their CUPS).

Very cool. I was expecting to learn about the ins and outs of ink, printheads etc but instead learned "How to build a paper that acts like a printer" which turned out much more entertaining.

Nice. I keep wondering if these devices would play nicer with DjVu rather than pdfs and raster formats? https://djvu.sourceforge.net/

In Linux it's pretty easy to create such things with cups. A while ago I did a cups backend for my Fujitsu Quaderno A4 [1]. It is super useful to be able to just open any document, in any program that supports printing, and then just "print" it to my device. [1] https://github.com/cristobaltapia/dpt-rp1-cups
