I came across a white paper called Barcode Printing 101 from one of our vendors Datamax Corporation that talked about barcode printing. It was one of the best reads I have seen in a long time. It talks about the different barcode symbologies and where they are used along with the media, labels and ribbons that are used to print barcodes. I have posted it in our resource section for all to read. Please feel free to read this and pass it along. Send us an email or call with any questions. We are always here to help solve a barcode related problem.
