Erreur serveur cups (après mise à jour noyau ?)

Gersei · Message par **Gersei** » lun. 11 nov. 2024 17:28

Bonjour,
Impossible d'imprimer depuis quelques jours, sur mon imprimante Epson ET 2810, la seule sur mon réseau. J'ai un message du genre "cups internal error".
J'ai désinstallé l'imprimante, impossible de la réinstaller, même message. Jai supprimé cups puis réinstallé, avec synaptics. Pareil...
L'imprimante fonctionne toujours bien avec un autre ordi du réseau.

à toutes fins utiles :

Merci Cyrille de ta réponse !
je ne sais pas trop où chercher pour répondre à ta question, voila par exemple ce que j'ai trouvé :
dans var/log/cups/error_log.1 j'ai ce genre de lignes :

J'espère que ça te parle plus qu'à moi...

Par contre dmesg, je ne sais pas du tout comment chercher

Gersei · Message par **Gersei** » mar. 12 nov. 2024 18:18

OK merci, je vais voir comment réinstaller le PPD

Gersei · Message par **Gersei** » ven. 15 nov. 2024 17:35

Sur google puis epson l'installation du PPD me renvoie sur l'installation du driver epson, c'est ça ?
J'ai téléchargé le .deb, il s'est installé automatiquement en me disant que le même paquet existait déjà, j'ai validé la réinstallation ... pareil.
Quand je veux installer mon imprimante, j'ai toujours l'erreur serveur cups...
Galère...

Au fait, pour dmesg :

Dans un message précédent, Cyrille avait remarqué : "Could not poll sufficient capability info from the printer ".
ça serait pas un pb résseau ?
Je ping l'imprimante depuis les ordis pour lesquels elle fonctionne, mais depuis celui qui pose le problème, j'ai :

Code : Tout sélectionner

YES ! C'était ça, j'avais openvpn actif ...

Merci Cyrille, sans ton analyse, je n'y serais pas arrivé
