Supplemental Program: Send ZPL directly to Zebra Printer

After downloading the .zpl file from above, use this Python script to print it raw over the network:

python zebra_label_printer.py --zpl-file PO12345-labels-xxx.zpl --printer-ip 192.168.10.50

The script is included in this folder. It uses only Python standard library (socket). Update the default IP in the script or pass it via argument.
