Installation réussie du scanner Epson ET-2850 mais échec pour l'imprimante

Germain1 · April 29, 2026, 10:55am

Bonjour tout le monde.
En attendant que le commerçant https://novacustom.com/ m’aide à résoudre un problème de signatures à cause d’une mise à jour de dom0 que j’ai faite,
pouvez vous m’aider à installer mon imprimante wifi multi-fonction Epson ET-2850.

Je suis novice pour Qubes Os et Linux.

Les templates présentes sont:

debian-fxce
default-dvm
fedora-42-xfce
whonix-gateway-18
whonix-workstation-18
whonix-workstion-18-dvm

Bonjour tout le monde.

J’ai téléchargé tous les pilotes et utility en ( **amd64.deb et en 64.deb.tar.gz ) sur ( https://download-center.epson.com/softwares/?device_id=ET-2850+Series&region=FR&os=DEBX64&language=fr ).

Je ne comprends pas pourquoi j’ai un échec dans l’installation de l’imprimante qui n’arrive pas à se connecter à la Livebox, alors que j’ai un succès d’installation pour le scanner…
Je soupçonne qu’il faille que je fasse pareil quand j’utilisais un macbook pro, c’est à dire que j’avais désactivé le wifi de la livebox et que je l’avais relier en rj45 à un deuxième routeur wifi.

J’ai cloné le template debian et j’ai coché au niveau de Net qube: sys-firewall (current)

Je me suis fait aidé de l’iA Grok pour installer le scanner avec les lignes de commande Debian dans le Terminal.

Voilà le contenu du Terminal:

Bonjour tout le monde. J’ai une imprimante/scanner Epson ET-2850. Je ne sais pas comment l’installer. La seule chose que j’avais réussi à installer était le scanner avant que je sois obligé de réinstaller Qubes OS à cause du fait que la mise à jours de dom0 avait remplacé ma disposition azerty par la disposition qwerty.

J’avais déjà fait cette demande et comme personne ne m’a répondu, je la réitère.

Y-a-t-il un tutoriel sur ce forum ou sur un autre forum?

Dois-je faire cette demande sur la partie anglophone du forum?

As tu fais une recherche ? Tu peux essayer avec le nom de l’imprimante, ou en cherchant “wifi printer” en anglais.

Je pense qu’il vaut mieux chercher comment l’installation se fait dans Fedora normalement, pour se faire une idée.

C’est assez spécifique et il y a beaucoup plus d’anglophones donc je pense que oui. Par contre, en règle générale, ne fais pas de doublon et quand tu crée un sujet dans deux langues différentes, met un lien vers le sujet précédent pour faciliter la compréhension.
