问题
I have a Motorola DS4208 barcode scanner that I have been using in combination with a program. The problem is I want to prefix the scans with some character so that the program knows an item was scanned by the scanner. I've tried following the user guide's instructions but instead of prefixing a character, the scanner prefixed a carriage return.

are you referring to the scanner product reference guide, you should be able to scan a series of barcodes to configure the scanner with a prefix as detailed on page 4-35 of this guide: https://www.zebra.com/content/dam/zebra_new_ia/en-us/manuals/barcode-scanners/ds4208-product-reference-guide-en-us.pdf
