Accès à mon serveur Cups

Support Debian
#1

Bonjour à tous,
J’ai un serveur cups qui fonctionnait avec mon imprimante Brother précédente, pendant quasi 10 ans.
A présent, j’ai changé l’imprimante, pour une Epson XP315 dont j’ai trouvé sur le site epson, un paquet debian (epson-inkjet-printer-201301w_1.0.0-1lsb3.2_i386.deb)
J’ai bien configuré cups, sur lp0 avec une configuration d’udev pour que ce soit automatiquement un lien sur /dev/usb0/lp0
J’arrive à imprimer, depuis l’interface cups, une page de test, donc à priori, je dirais que ce doit être bon!

Mon problème vient des machines du réseau locale:
je tente de configurer sur mon portable (sous mint), l’imprimante:

cat /etc/cups/client.conf
ServerName 192.168.3.1

dans les log de cups, j’ai ceci:

mais sur mon portable, je n’arrive pas à configurer cette p… d’imprimante:
les messages vont de “recherche de pilote…” sans réponse, à "

Une erreur s'est produite lors de l'opération CUPS : « Succès ».

et pas de d’imprimante configurée

Une erreur s'est produite lors de l'opération CUPS : « Mauvais descripteur de fichier »

Je comprend pas pourquoi je n’arrive pas à atteindre mon imprimante.
si quelqu’un veut me donner un coup de main, je veux bien.

Merci.
Rémi.

Voilà, quand on est trop bête, on réfléchit pas…
J’avais installé le drivers générique Epson et le drivers Epson xp315. Ce qui explique les conflits. Par contre les messages d’erreurs ne sont pas toujours facile à décrypter…
Donc j’ai supprimé le générique et ça fonctionne.
Problème résolu.

Edit:
pour info, et que cela soit utile à d’autre, j’avais mis ces deux paquets:
printer-driver-escpr et epson-inkjet-printer-201301w. Le premier est le drivers générique (pilote d’impression pour les imprimantes à jet d’encre Epson utilisant ESC/P-R) le second le pilote pour les imprimante xp312/xp315 et xp412, d’Epson.
J’avais oublié de mettre les nom des paquets.
