Bonjour à tous

J'essaie d'installer une nouvelle imprimante sur mon lenovo sous Ubuntu 20.04.2 LTS mais rien ne fonctionne.
J'ai réussi à imprimer les feuilles d'essai et depuis plus rien.
Sur le site de canon, point de salut si tu n'es pas sur windows.
L'imprimante est connectée en filaire et en réseau.
pas d'imprimante ni de scanner .
Quand je trouve le réseau de l’imprimante, il me demande un mot de passe ????

Bonjour xubu1957
j'ai suivi le tuto et recommencé ce matin mais en dernière ligne :

Bonjour,

Je ne suis pas au point pour l'aide dans cette section.

J'essaye d'aider à partir de discussions résolues pour un modèle donné.

_ _ _

La sortie de ce modèle est récent > labo.fnac.com/actualite/canon-pixma-ts3450 et je ne trouve pas de discussion pour Linux.
Merci quand même.
Une autre bizarrerie du système.
J'ai installé gscann2PDF, un outil de scann et j'ai réussi à scanner et à imprimer ma feuille.....
mais toujours pas possible d'imprimer une feuille sous openoffice ni pdf.
Bonne journée
Pascal
