The POS application I used to sup****t was written in Cobol (AcuCobol).
The scanner itself (name I cannot remember, but they were big back in '98)
was written in C. This scanner did inventory, mainly, and you could scan a
great deal of stuff before actually needing to hook up and download the
data
to the application.
Many scanners are also simply UPC converters, that take UPC, convert to
text, and send that to your PC. This can be an embedded language of any
type, usually C.
