I have a receipt printer I was using for grocery lists. I still haven't found a good use for it yet. I love how extremely fast it is though and it has auto cut. Maybe I can use it for a ticket system at work.
Earlier quoted context omitted.
BPA free thermal paper has been around for a while. A few years ago, I bought a box of it for a similar project (JIRA events -> Receipt printer)
I think "BPA free" means "BPS". I think that's less-studied but not necessarily better. [Edit: but "phenol-free" is likely actually safe, thanks for pointing that out. I should read my own link fully!]
Those blue receipt papers seem okay though: https://www.koehlerpaper.com/en/products/Thermal-paper/Blue4...
The only logical next step here is to get that metal spike thing, so you can stab closed issues on completion.
This is a fun idea, but I've read thermal paper is surprisingly nasty stuff. [Edit: unless it's advertised as "phenol-free".] It's not just paper. It contains plastics (BPA or BPS) that you absorb through your skin when handling it. I'd avoid working with receipts at my desk all day. (I'd also avoid being a grocery store cashier...) https://www.pca.state.mn.us/green-chemistry/bpa-thermal-pape...
These printers are fun. I got one from a hardware swap meet a few years back and used the same software to work it into a public art project I did a bit later. You could listen to or record your own “dream” story to a kiosk, and upon leaving one, you’d get a paper receipt. It was a fun, tangible interaction that gave a bit of permanence to something purely audio. https://justinmiller.io/services/dreamdial1.jpg
You can get Fuji printers which use Instax film, or Canon makes a similar one they call the Selphy, or there's the Zink printer line as well.

that explains why it tastes so bad
This is a really funny read for a Friday morning. It should play an MP3 of a line cook in a busy diner shouting, "Order up!", and then he can stick it on a rotating order wheel hanging above his desk. EDIT: One of these things: https://www.webstaurantstore.com/choice-stainless-steel-orde...
I hope he at least has one of those receipt spikes to stick it on when the issue is closed.
Although I’ve always had problems with sharp corners. For instance, if I’m reading in a chair and there’s a small table next to me and the corner is sharp, I can’t handle it and have to cover it (like set a book so it’s hanging over the edge). It bugs my eyes for some reason. Same if I’m watching TV and there’s furniture with sharp corners near the TV.
I really hate that this affects me so much, so mostly sharing in case someone else deals with this or knows what’s going on.
Quick question though. Why go through all the hassle with the custom udev rule and dialout group if you are just using sudo to run the script after all?
If the author is here - please include pictures of the printer and output in the article! There is an embedded twitter video, but it seems more aligned with the spirit of the project to use the traditional visual aids :)
