Barcodes in ZPL

How to print each barcode type in ZPL: the command, the data it accepts, the parameters that change its size, and a generator that renders it as you type. Use Code 128 (^BC) for shipping and logistics, EAN-13 or UPC-A for retail products, QR (^BQ) for links, and Data Matrix (^BX) when the label is small. Each page shows the size in dots at 203 and 300 dpi, so the code scans the first time.
