Re: Bar code printing

Escape code alone will not work. You need the font. If you are using PC, there are plenty of free fonts on the net. The next issue is how you plan to read the barcode back? Some kind of barcode readers, right? If you do plan to read the barcode labels (otherwise they are useless), you need to insert start and stop bits (or characters).
