QUand j'essaie de lancer une impression d'une page de test via le serveur cups : http://localhost:631/printers/Deskjet-6940-series

j'obiens ces messages suivants :

Par contre dmseg ne me donne rien. Auncun log n'est écrit : 

lts@home:/var/log$ tail -f dmesg

Je pense que le message clef de l'erreur est celle-ci :

erreur a écrit :

failed to CreateProfile: org.freedesktop.DBus.Error.NoReply:Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

SI j'essaie de comprendre le message d'erreur du ffichier de log de cups
QUelques choses ne recoit pas une réponse.
La probable erreur serait
- soit que l'application distante ne renvoie pas une réponse. => ma question, de quelle application distante parle t-il ?
- soit qu'il y a une politique de sécurité qui bloquerait la réponse. J'imagine qu'il veut parler entre le client et le serveur CUPS. Pour ma part, j'ai laissé la config de Ubuntu par défaut. Je n'ai pas Firewall ou quoi que ce soit.
- soit la réponse à expirer par timeout
- soit la connection réseau est tombé => la connexion à l'imprimante se fait en usb

Du coup dans ses supposition, il ne m'a pas trop aidé

Re : Imprimante HP qui n'imprime que l'entete de page

Pfff, cela n'est plus à y comprendre, ma mère vient d'imprimer et cela a fonctionné. Il s'agit pour son boulot, d'un document qu'elle a imprimer à partir de Firefox. Elle a cliqué sur le bouton "Imprimer" (un bouton html) qui génére du PDF. Je reconnais l'interface du haut avec la possibilité de le télécharger. Elle a lancé l'impression et cela a fonctionné.

Je voulais donc mettre le syslog qui a été généré pour info si cela peut aider.

Donc j'ai l'impression que cela dépend à partir de quel logiciel on imprime. A partir de Firefox il semblerait que ce soit okay.

Essaie de la supprimer et de l'installer : lire hplip pour cela.

Re : Imprimante HP qui n'imprime que l'entete de page

Hello tout le monde, je reviens vers vous que là, parce que je n'étais pas chez mes parents depuis.

Contexte
Pour rappel, j'ai des documents qui s'imprime parfaitement et d'autres non.
Comment cela se manifeste ?
L'imprimante commence l'impression sur quelques lignes puis s’arrête d'un seul coup. L'imprimante garde donc. Et au bout de 3-4 min (ou plus), l'imprimante fait défiler sans plus rien imprimer. On se retrouve donc avec une page avec l'entête.
Je redemanderais un peu plus le détail à mes parents.
Quel sont les documents ne sont pas bien imprimé ?
Aucune idée. J'ai essayé d'identifier les documents qui ne s'imprimer pas correctement mais pas moyen de savoir.


grigouille, j'ai même fait mieux, j'ai installé sur le PC de mes parents Ubuntu Xérial 16.04 (et j'ai enfin réussi à faire fonctionner correctement le wifi qui ne fonctionnait plus sur cette version smile ) en parallèle de la version qu'il utilise Trusty 12.04.
L'imprimante toujours en USB à été testé avec un nouveau HP Lib. Malgré cela j'ai rencontré le même problème.

La version de HP Lib utilisé sur la nouvelle installation : celle de base, à savoir la version 3.16.3

xerial@xerial-System-Product-Name:/home/lts/.mozilla/firefox$ hp-info 

HP Linux Imaging and Printing System (ver. 3.16.3)
Device Information Utility ver. 5.2

Done.

Parmi les commandes HP-<truch much>, je découvre comment lancer une page de test en ligne de commande, je teste  : 

xerial@xerial-System-Product-Name:/home/lts/.mozilla/firefox$ hp-testpage 

HP Linux Imaging and Printing System (ver. 3.16.3)
Testpage Print Utility ver. 6.0

Et a ma grande surprise, l'imprimante se met à imprimer d'une seule traite la page de test, sans s’arrêter au bout de 3-4 ligne. Youpi  smile


Je découvre par hasard également la commande hp-diagnose_queues. Je teste :

xerial@xerial-System-Product-Name:/home/lts/.mozilla/firefox$ hp-diagnose_queues 

HP Linux Imaging and Printing System (ver. 3.16.3)
AutoConfig Utility to check queues configuration ver. 1.1

warning: Insufficient permission to access file /etc/cups/ppd/Deskjet-6940-series.ppd

mais apparement, il faut les droits root, je resteste : 

xerial@xerial-System-Product-Name:/home/lts/.mozilla/firefox$ sudo hp-diagnose_queues 
[sudo] Mot de passe de xerial :

warning: 2 queues of same device Deskjet-6940-series is configured.  Remove unwanted queues.
error: 2 queues of same device Deskjet-6940-series is configured.
Remove unwanted queues.

Apparemment, j'ai 2 files avec le même périphérique de configuré. Okay soit. Il supprime comme un grand.


Et deviner, le document que mon père essayait d'imprimer s'imprime correctement. Youpi de nouveau !!
Bref à voir, j'ai peut être trouvé le truc bloquant. Je ferais lancé cette commande si besoin la prochaine fois.

Affaire à suivre
