Je ne sais pas pourquoi hplip n’a pas détecté ton imprimante. On va tenter autre chose.
sur son site, rubrique téléchargements HP fournit une archive pour ton imprimante “uld-hp_v1.00.39.12_00.15.tar.gz”, déballe-la et exécute le install.sh avec le terminal.

    je ne le conseillerais pas. L’utilitaire HPLIP Graphic Tools est fait pour cela et est fait par HP. Pour l’instant il ne l’a pas encore utilisé ou on a pas encore le résultat.

      En effet c’est une autre application que j’ai affiché, mais j’ai bien testé l’option HPLIP Graphic Tools.
      Lors d’une tentative de détection avec l’option Network/Ethernet/Wireless network, j’ai ceci :

      HPLIP cannot detect printers in your network.
      This may be due to existing firewall settings blocking the required ports. When you are in a trusted network environment, you may open the ports for network services like mdns and slp in the firewall. For detailed steps follow the link. https://developers.hp.com/hp-linux-imaging-and-printing/KnowledgeBase/Troubleshooting/TroubleshootNetwork

      J’ai aussi testé avant de créer ce fil de discussion : d’abord en installant install-printer.sh, puis install.sh.

      Le message dit qu’il est possible que ce soit le pare-feu qui bloque la découverte de l’imprimante.
      Arrête momentanément le pare-feu et réessaye.

      sudo systemctl stop --now firewalld
      hp-setup -i 192.168.1.12

        Voici ce que dit cups

        Ports Used for Printer Sharing
        Table 1 lists the ports that are used for IPP printer sharing via CUPS.
        
        Table 1: Ports Used for IPP Printer Sharing

            On en est au même point, hplip ne voit pas l’imprimante.
            Installe le package nmap , appuie sur le bouton marche/arret de l’imprimante pour qu’elle sorte de veille, il faut que le témoin wifi soit stable et non clignotant. Poste le retour de:
            nmap -sP 192.168.1.0/24
            Éteins carrément l’imprimante et poste encore le retour de la même commande.

              Sortie de veille de l’imprimante et témoin wifi stable : OK.

              Non ce n’est pas le même résultat, dans le 1er tableau il y a 11 hosts, dans le 2ème il y a 10 hosts. c’est l’imprimante qu’on a éteint qui manque. c’était juste une vérification, son adresse ip est bien 192.168.1.12
              On vérifie si cups est lancé, il me semble qu’a l’installation il est désativé.

                  Merci pour toute l’aide que vous m’avez apportée, bonne continuation !
