OT: someone please make a RPi image that "prints" a page to an eink display. I want to duct-tape an RPi Zero and a rechargeable battery to the back of a display, then be able to print recipes to it while cooking. Other people might print board-game rules or speech notes while rehearsing -- anything that you'd typically print and then throw away after brief usage.
I know I could make a PDF, sideload it to a Kindle, etc. Too many steps. I just want the display to appear as a printer on my phone.
- IlikeKitties 1y agoSounds pretty vibe codable, why don't you try it yourself?
- xrendan 1y agoI have some really old code that pretty much does this, I'll see if I can find it.
- xrendan 1y agoUgh, I don't have it. It was from before I used git. Basically to do this you have a cups server that exposes itself as a network printer that prints to a specified PDF directory and then you have a program watching that directory for new files and if there's a new one it opens up whatever pdf viewer you want in full screen.

- navane 1y agoI always wanted to tackle this use case with receipt printers, those thermal narrow paper rol ones. But those things are freaking expensive!
- colechristensen 1y agoRestaurants are going out of business all the time, there's your source
- literalAardvark 1y agoThermal paper has some pretty horrible effects on your health, I'd avoid that.
- whartung 1y agoJust curious if the folks at CVS chart particularly high on these horrible effects, considering the no doubt thousands of feet of receipts they handle each day there. For those unaware, at the CVS Pharmacy if you walk in and buy so much as a pack of gum, you're likely to walk out with at least 3 feet of receipt. They use them to tack on ads and coupons.
- literalAardvark 1y agoProbably, idk if there are such specific studies. The thermal sensitive layer contains very large amounts of BPA in a dusty form that will easily contaminate your hands. BPA is a major endocrine disruptor. They might say BPA-free, which would be technically correct, but that just means they'll use a near identical BPA variant that isn't proven to be an endocrine disruptor yet. Handle with care, wash your hands, don't put them in the kitchen.
