I have following ZPL code to generate the Barcode.

Thank you!

Solution

  • I'm not sure calling '^BY' with no values is doing any good, and '^PQ' is set to the default values making it redundant. But regardless, you're passing too many digits in '^FD'. Zebra wants to add it's own checksum:

    Field data ( ^FD ) is limited to exactly 12 characters. ZPL II
automatically truncates or pads on the left with zeros to achieve the 
required number of characters

    See p101 of the Zebra Programming Guide for details. If you need to encode the 9 (which is not the correct checksum) then you should look at EAN14(or GTIN14).
