- script_print.sh : après lp, polling CUPS + sondage IPP direct ipp://IP:631/ipp/print Détecte input-tray-missing / media-empty en ~3-6s sans attendre le timeout CUPS - printer_service.py : ajout _get_printer_ip(), _query_ipp_direct() _get_printer_status() utilise IPP pour état/raisons/encre (source de vérité) - Timeout porté à 120s côté Python, fallback lpstat conservé
