Imprimante wifi qui n imprime pas mais numerise bien

[alex323]

Bonjour ,
Impossible de lancer une impression . J'ai ces messages d'erreur : "Un filtre d'impression est manquant sur l appareil ".
Egalement : "Stopping job because the sheduler could not execute the backend" .
Lors du dépannage proposé par l'imprimante: File "usr/lib/cups/backend/implicitclass" not available. No such file or directory

Imprimante HP DeskJet 4122e , qui numérise bien et marche tres bien sur 2 autres PC Linux
Qu'en pensez vous ?

Dans un premier temps, supprimer et réinstaller l'imprimante
Sinon que retourne

Code : Tout sélectionner

aptitude search  printer-driver-hpcups

Ainsi que les logs d'erreurs de cups ?

[alex323]

J'ai deja reinstaller l 'imprimante .Suite à ta demande , la réponse est : i printer-driver-hpcups - impression et traitement d'image HP pour Linux.
Quant aux logs d'erreur de cups ,comment les obtient-on ?
Je te colle aussi les premieres lignes du résumé Troubleshoot quand l'imprimante propose de dépanner .
