    Free Barcode Generator VB.NET

    Easily create and print codebar labels to any application

    This project uses as engine the powerful library ZEN BARCODE. The reason why this project exist, it's because there was not a way to add a description and codebar number to any codebar label using only Zen Barcode, so I added a few tweaks to make a printable (and useful) label including all mentioned stuff. Hopefully can be of help to anybody in help of print codebar labels, but ideally some people will help to expand its functionalities to make this tool a kind of "de facto" standard to print codebars.
