Try the following steps to troubleshoot barcodes which do not scan and give expected results.

1. Try to scan the barcode into Notepad or Microsoft Word. Check for missing or incorrect information in the output

2. Ensure the barcodes is at least 12 point 3 of 9 barcode font 
   NOTE: Some scanner may require larger fonts, so increase font size until readable

3. Ensure we have our batch set up so the scanned information enters the correct fields.

4.  Delimiters
When producing Code39 barcodes using some barcode fonts, (this commonly occurs with free Code 39 barcode fonts) you may need to delimit the barcode data with asterisks (*). If you wish to produce the barcode WITHOUT having the characters appear as part of the barcode, use parentheses around the data “ ( ) “.  This is independent of printer/scanner used.
