No warranty. From the GNU barcode documentation:

Please take the "no-warranty" disclaimer seriously: even though I spent reasonable efforts to make sure the output is useable in production you should verify it suits your needs as a faulty bar can cost you a bundle, and you'll be on your own. It's up to you to verify that the symbol is valid (and, obviously, I'd like to know about any problem you encounter). [This paragraph copied verbatim from]
