This software provides a free Code 39 Barcode Font that supports printing of letters, numbers and select symbols using the Code 3 of 9 symbology.

The font file provided is TTF and digitally signed with TrueType outlines. This ensures that the font is fully functional and reliable. To generate a Code 39 barcode from this font, all you need to do is surround your data-to-encode with asterisks as the start and stop characters, like *153969*.
If you're using Microsoft Word, you'll need to change the start and stop characters to "!" instead of the asterisk. This is due to a formatting issue. So, your data-to-encode should be surrounded by "!" characters, i.e. !153969!.
One of the nifty features of this font is the ability to hide the asterisks from appearing in the human-readable below the barcode. You can do this by using parenthesis surrounding the data. For example, (12345).
All in all, IDAutomation's Free Code 39 Barcode Font is a great option for businesses and organizations looking to generate barcodes easily and efficiently.
