alt Hacker NewsHow to build a printer
Comments
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.
Good job, but I’m left wanting to know how to build a printer.
This is amazing!!! It just makes sense. And its just how you would want to use a e reader.
I don't understand the purpose. What am I missing?
The author "prints" to the eink display. Why not load say the pdf directly?
I love the concept, but I wonder why he wasn’t printing to PDF. Can this device not render PDFs?
This is a fantastic idea!
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.
Outstanding! This is so...correct.

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).
