Bonjour. Je rencontre un problème inédit.
J'ai bien utilisé le script d'installation brother qui m'installe tout et paramètre tout.
Le scanner fonctionne très bien
Mais l'imprimante ne fonctionne pas.
un brsaneconfig3 -d me donne plein de bonnes indications. Même les ping fonctionnent, mais l'imprimante elle ne veut rien savoir....
J'ai utilisé le logiciel de désinstallation, mais il n'a rien pu faire. J'ai donc supprimé la directory /opt/brother/ complètement puis ai tout réinstallé. Le problème reste entier.
Même avec cups, je n'ai pas pu la désinstaller.
Avant de tout reformater à la windows, j'aurais voulu faire une tentative de réparation. Donc si vous avez des idées je suis preneur.
Merci.
installation en root ou user ?
désinstalles en root
Merci antbel. J'ai effectivement oublié de préciser, car pour installer ou désinstaller un RPM, ça ne peut se faire qu'en root.
J'ai un petit portable et je vais essayer avec pour voir s'il y a eu une mauvaise installation, avant de tout reformater.
6 jours plus tard
Ce soir j'ai fait l'essai avec pour mon petit PC Acer .
Mon imprimante MFCJ870dw fonctionne.
L'imprimante chez MFCJ265w mon amie ne fonctionne pas.
J'ai lancé le diagnostic:

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

  # No USB scanners found. If you expected something different, make sure that
  # you have loaded a kernel driver for your USB host controller and have setup
  # the USB system correctly. See man sane-usb for details.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

Désolé, mais ton post est vraiment confus.
- il y a combien de PC ?, comment communiquent ils entre eux ?
- il y a combien d'imprimantes ? comment sont -elles branchées ?
- Que veut tu faire exactement avec tes imprimantes.
- CUPS est ton ami
Bonjour antbel.Je me suis mal exprimé dans ce thread. On a une imprimante MFC-J265W branchée sur un LAN en wifi. Les PC fedora n'accèdent pas à l'imprimante. Sous Mint ça fonctionnait directement (J'ai supprimé les Mint). Les tablettes android peuvent imprimer sans problème.
Pour être sur que le problème ne soit pas dans un seul PC, j'ai ramené un portable de chez moi, pour tester cette imprimante.
Chez moi, il y a un autre LAN avec une autre imprimante Brother qui fonctionne parfaitement. C'est juste ce point que je voulais exprimer. On est donc sur problème assez spécifique.
J'espère être un peu plus clair maintenant.
La première chose à voir c'est le paramétrage de ton imprimante sur le premier LAN où il y avait les Mint.
L'imprimante doit être en IP fixe et ne doit pas prendre une ip d'une autre machine

Chez moi la règle c'est une question de goût aussi : une plage de 10 ip est réservée pour un type de fonction.

192.168.XXX.001 à 192.168.XXX.009 ----------> Les serveurs
192.168.XXX.010 à 192.168.XXX.019 ----------> Les imprimantes
Ensuite les stations de travail ont toutes une ip fixe à partir de 192.168.XXX.020
Ensuite les android & Co à partir de 192.168.XXX.128
Questions d'organisation

Pour les android & Co je les laisse en DHCP mais la connexion au wifi est filtrée par la MAC adresse de l'appareil avec un ip selon les règles ci-dessus.
Avec les pilotes propriétaires Brother indique les prérequis suivants:
- installation de glibc.i686
- ouverture des ports: port entrant UDP Port 54925 et port sortant TCP Port 54921
- possibilité de donner une autorisation à selinux

Pour tester désactive temporairement le pare-feu et selinux puis redémarre cups.
