Thermal Printer

We are a large health system and have a mix, but I believe most these days are indeed thermal because the wristbands are plastic.  I can say that we very, very seldom have scan errors with the thermal barcodes.  Like <0.01%.

We use thermal at my hospital and sometimes have a problem with either not scanning the bracelets or scanning and getting a weird digit for some reason (Like ' instead of the number 1).
I was told that there was a time when all the bracelets were doing that. They tried changing the contrast (?)/darkness of the printer and ended up I think having to change wristband suppliers.
