### 🚨 Troubleshooting:
#### Service Won't Start:
```cmd
# Check service status
sc query QualityPrintService
# Check port availability
netstat -an | find "8765"
# View service logs
type "%USERPROFILE%\\PrintService\\logs\\print_service_*.log"
```
#### Python Issues:
The installer automatically detects Python or uses portable version.
If you see Python errors, ensure Python 3.7+ is installed.
#### Chrome Extension Issues:
