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)

- scottlamb 5y agoI 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!]
- flotzam 5y agoYeah they're "BPA free" in roughly the same sense that 1P-LSD is "LSD free" Those blue receipt papers seem okay though: https://www.koehlerpaper.com/en/products/Thermal-paper/Blue4est-thermal-paper.php https://www.koehlerpaper.com/en/products/Thermal-paper/Blue4...
- outworlder 5y agoThe article linked in the comment says this: "If you must give paper receipts, look for “phenol-free” paper, which is safer for human health and has fewer environmental effects. Three types that do not contain BPA or BPS and are competitively priced contain either ascorbic acid (vitamin C), urea-based Pergafast 201, or a technology without developers, Blue4est. The latter uses a coating that reveals an underlying dark layer when heat is applied."
