I typically decline those.

Thermal paper was widely used for fax machines and portable printers years back as well.

Worse: I worked in grocery stores for years as a cashier lol

I did too but the printers were still dot matrix with ink ribbons then.

I rarely see thermal printers at grocery checkouts. Almost all that I see are ink.

What country is this? I haven’t seen a dot matrix printer at a store in a decade.

Fun fact: when Apple first opened retail stores, they printed receipts on big Lexmark laser printers, 8.5x11, on VERY nice paper, like resume paper, it was absurd how nice and thick the paper was. It was preprinted with return policies etc on the back (and maybe a color Apple on the front?) It only lasted a few years like that and they eventually got cheap thermal printers installed.

In the US. Maybe I am wrong but I see what appear to me to be multicolor ink jet POP printers. I see matrix in restaurants and shops and they are distinct as they are slow and noisy.

I'm pretty sure I ate some as a bet in high school.
