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 also send "post" data, such as a <CR> or some other kind of identifier that indicates that the scanner has completed a good scan.
Scanners can be programmed to ignore some types of barcode and not others.
It all depends on the needs of the individual application.

You simply point the reader at the bar-code - and it scans the sequence of black & white lines, sending data to a computer - which tells the user what the product is. With a keyboard, you would have to enter the long string of numbers printed under the bar-code - which not only takes more time - but could be entered wrongly.
