+## Service Management
+
+### Using Service Control Manager
+```batch
+# Start service
+sc start QualityRecticelPrintService
+
+# Stop service
+sc stop QualityRecticelPrintService
+
+# Check status
+sc query QualityRecticelPrintService
+
+# Restart service
+sc stop QualityRecticelPrintService && sc start QualityRecticelPrintService
+```
+
+### Using Services GUI
+1. Press `Windows + R`, type `services.msc`
+2. Find "Quality Recticel Print Service"
+3. Right-click for start/stop/restart options
+
+### View Logs
+Service logs are automatically written to:
+```
+C:\Program Files\QualityRecticel\PrintService\print_service.log
+```
+
+## Troubleshooting
+
+### Service Won't Start
+1. **Check Administrator Rights**: Ensure installer was run as Administrator
+2. **PowerShell Execution Policy**: Verify PowerShell execution policy allows scripts
+   ```powershell
+   Get-ExecutionPolicy
+   # Should be RemoteSigned or Unrestricted
+   ```
+3. **Port Conflict**: Check if port 8765 is already in use
+   ```cmd
+   netstat -ano | findstr :8765
+   ```
+4. **Service Logs**: Check the log file for detailed error messages
+
+### Printing Issues
+1. **Printer Access**: Verify printers are accessible from Windows services
+2. **PDF Access**: Ensure PDF URLs are accessible from the service context  
+3. **Print Queue**: Check Windows print queue for stuck jobs
+4. **Permissions**: Verify service has permission to access printers
+
+### Chrome Extension Issues
+1. **Service Connection**: Test http://localhost:8765/health in browser
+2. **Extension Loading**: Verify extension is properly loaded in Chrome
+3. **CORS**: Service includes proper CORS headers for browser access
+4. **Console Errors**: Check browser console for JavaScript errors
+
+## Security Features
+
+- **Localhost Only**: Service only accepts connections from 127.0.0.1/localhost
+- **No External Access**: No outbound network requirements except for PDF downloads
+- **Temporary Files**: PDF downloads are cleaned up automatically
+- **Service Account**: Runs with minimal required privileges
+- **CORS Protection**: Proper cross-origin resource sharing headers

+# Right-click and "Run as administrator"
+uninstall_service.bat
+```
+
+### Manual Uninstall
+```batch
+# Stop and delete service
+sc stop QualityRecticelPrintService
+sc delete QualityRecticelPrintService
+
+# Remove files (optional)
+rmdir /s "C:\Program Files\QualityRecticel"
+```

+- `System.Net.WebClient` for PDF downloads
+- Native Windows service architecture
+
+### Why PowerShell vs Python?
+- **Deployment**: No need to install Python runtime or pip packages
+- **Security**: Uses only Microsoft-signed components
+- **Performance**: Faster startup and lower memory usage
+- **Maintenance**: Easier to troubleshoot with native Windows tools
+- **Enterprise**: Better compliance with corporate security policies
