Need to scan a carriage return

I need to scan a carriage return. I do not want to code my scanner to do the carriage return automatically after the scan. The reason being that sometimes I need to scan one, two or maybe three barcodes before I need the carriage return.

I want the user to have a print out of the carriage return bar code taped to their computer so they can scan the "carriage return" barcode when needed which will eliminate the need to let go of the scanner and hit the enter key.
