"""
|
||||
### 🛠️ Technical Features:
|
||||
|
||||
#### Printing Methods (Automatic Fallback):
|
||||
1. Adobe Reader command line
|
||||
2. SumatraPDF automation
|
||||
3. PowerShell printing
|
||||
4. Microsoft Edge integration
|
||||
5. Windows system default
|
||||
|
||||
#### Service Architecture:
|
||||
```
|
||||
Quality Web App → Chrome Extension → Windows Service → Physical Printer
|
||||
(localhost only) (port 8765) (any printer)
|
||||
```
|
||||
|
||||
#### Service Endpoints:
|
||||
- `GET /health` - Service health check
|
||||
- `GET /printers` - List available printers
|
||||
- `GET /status` - Service statistics
|
||||
- `POST /print_pdf` - Print PDF (page-by-page supported)
|
||||
|
||||
### 🔒 Security & Performance:
|
||||
- Runs on localhost only (127.0.0.1:8765)
|
||||
- Memory usage: ~15-30 MB
|
||||
- CPU usage: <1% (idle)
|
||||
- Automatic temp file cleanup
|
||||
- Secure PDF handling
|
||||
|
||||
### 🚨 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:
|
||||
1. Reload extension in chrome://extensions/
|
||||
2. Check "Developer mode" is enabled
|
||||
3. Verify service responds at http://localhost:8765/health
|
||||
|
||||
### 📞 Support:
|
||||
1. Check README_COMPLETE.md for detailed documentation
|
||||
2. Review INSTALLATION_COMPLETE.md for step-by-step guide
