owv QRprint Windows Print Agent

1. Download this ZIP and extract all files into one folder.
2. Install Python 3.10 or newer and SumatraPDF on the printer PC.
3. Double-click Start-Agent.bat from the extracted folder.
4. On first run, enter the server base URL (the site address, not the /s/shop customer page) and private agent key shown in your shop dashboard.

Keep agent.py, Start-Agent.bat, and requirements.txt together in the extracted folder. The launcher automatically starts agent.py from that folder. Python packages are installed by the agent when needed.

Keep your private agent key secret.
