Typically just the data that the reader encountered. If it's a UPC code the scanner would output the data on the barcode.
Most scanners can also be programmed to include some kind of preamble data, which may simply be a beginning of text marker or an identifier from the scanner.

Scanners can be programmed to ignore some types of barcode and not others.
It all depends on the needs of the individual application.
