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...)

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 :)

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!]

This is awesome. I'm a solo dev and I created an electron app named Label LIVE. I recently added an HTTP API so you can fire off label jobs using a POST request (or retrieve label PNGs via GET). What Label LIVE affords is a WYSIWYG imaging pipeline that can target many different thermal printers at the correct DPI, or generate/submit PDFs to a printer (system or network). If you mention this note and your project, I'll send you a free license for "testing." :D (and no, no direct Linux-Desktop support yet, sorry!)

that explains why it tastes so bad
