The PDF linked below is a configuration document to program certain Wasp 2D scanners to send both FedEx and USPS tracking numbers (only) when scanning their barcodes (as of March 2022). These scanners should be able to read the configuration barcodes from a computer monitor, or the pages can be printed out. Scan all the barcodes top to bottom on all pages to compete the programming.
