For professional reasons, I had to become interested in barcodes. Surprise ! There's nothing free on the internet, it seems terribly complicated and we're already considering having to buy a bunch of specific tools. In reality, after reading some scattered documentation, everything becomes very simple. I carried out all my tests with basic equipment: HP laser printer, Canon S600 inkjet printer and DC 200 type barcode scanner (The first price). In the following pages I will provide you with the entire software part... free as usual. !

Here everything is under the GNU - GPL license, that is to say free, open source and completely free...
