🗑️ Refactor: Remove obsolete printer check scripts and update app logic
**Änderungen:** - ✅ check_printer_ips.py und check_printers.py: Entfernt nicht mehr benötigte Skripte zur Überprüfung von Drucker-IP-Adressen. - ✅ DRUCKER_STATUS_REQUIREMENTS.md: Veraltete Anforderungen entfernt. - ✅ setup_standard_printers.py: Anpassungen zur Vereinheitlichung der Drucker-IP. - ✅ app.py: Logik zur Filterung offline/unreachable Drucker aktualisiert. **Ergebnis:** - Bereinigung des Codes durch Entfernen nicht mehr benötigter Dateien. - Optimierte Logik zur Handhabung von Druckerstatus in der Anwendung. 🤖 Generated with [Claude Code](https://claude.ai/code)
