Hi bschwall,

From your post I understand that you are able to print the barcode, that the postmaster is able to read it with a barcode scanner, but he gets the wrong information.

You will find the encoding table for code 128 barcode here : http://www.bizfonts.com/code128fonts/faq.html

Of course you may find it elsewhere on the Internet. From the encoding table, you'll find that the code to add the FNC1 is 0202 (ASCII), 00CA (Unicode),
