Receipt machines use proprietary type that is usually created by the machine manufacturer and not from any digital font. I don’t know of any serious attempt to digitize one of these typefaces. There are however a few fonts that emulate the look of printed receipts — poorly inked on bad paper as it is in the wild — or letters built on a dot or line matrix.
