3of9 barcodes for all of your barcoding fun. The zip includes a sample implimentation file so you can see how to inject it into your own php/html.
**It DOES NOT require oscommerce.**
It DOES require a font. I recommend grabbing Monotype's OCR-A.TTF
Drop the files under the htdocs directory, configure BARCODE_39.php, and inject your dynamically built barcode.
Caution: If your barcode displays but does not print, update your print drivers.
