Normally, you need delimiters. For example, when you are using the 3of9 barcode font, you need to add * has a prefix and a suffix to your data.

ie: if you want to barcode ABC123, you need to print *ABC123* as the barcode.

Is it working? I don't have a barcode to test it. And I also didn't look thoroughly the specification!
