🖨️ QZ Tray Required for Printing

This app uses QZ Tray for direct label printing (no browser print dialogs)

Step 1: Download & Install QZ Tray

1. Download QZ Tray from: https://qz.io/download/
2. Run the installer (Windows: qz-tray.exe)
3. QZ Tray will run in your system tray (look for the QZ icon)
4. QZ Tray must be running for printing to work

Step 2: Connect Your Printer

1. Connect your LabelRange BT620 printer via USB or Bluetooth
2. Install the printer drivers if needed
3. QZ Tray will automatically detect your printer

Step 3: First-Time Setup (Certificate)

If you see "UNTRUSTED REQUEST" when printing, the server administrator needs to set up QZ Tray certificates. See QZ_TRAY_SETUP.md for instructions.

Troubleshooting

• "QZ Tray is not available": Make sure QZ Tray is installed and running (check system tray)
• "Cannot read properties of null (sendData)": QZ Tray may not be connected. Try: (1) Restart QZ Tray, (2) Refresh this page, (3) Check if QZ Tray icon shows in system tray
• Labels not printing:: Verify BT620 printer is connected and powered on. Check QZ Tray's printer list.

💡 Tip: Keep QZ Tray running in the background. You can set it to start with Windows in QZ Tray settings.
