Bonjour,
Je viens d'acheter une imprimante HP DeskJet 2722 pour imprimer et scanner. Mon ordi est en ubuntu 20.04
hplip 3.20.3 n'a pas reconnu l'imprimante.
J'ai lu qu'il fallait au moins hplip 3.20.5 pour la série 2700 mais que ça ne fonctionnait pas parfaitement bien avec ubuntu 20.04
J'ai essayé d'installer hplip 3.20.11 qui est donné pour supporter ubuntu 20.10
L'installation a planté avec
error : command failed with error 100
sudo apt-get install --assume-yes python-pyqt5

Et puis ensuite avec python-dbus.mainloop.pyqt5 et avec python-notify et avec python-reportlab

Que faire ?
. reprendre avec hplip 3.20.5 ?
. installer pyqt5 avant hplip 3.20.11 ?

Mon installation :

Résumé de la résolution du problème :
---------------------------------------------------

J'ai téléchargé hplip-3.20.11.run depuis le site 
https://developers.hp.com/hp-linux-imaging-and-printing
Et j'ai choisi le mode d'installation conseillé dans la doc : hplip
. en mode "custom"
. avec l'option sans support graphique (sans GUI)
. sans fax
. en mode interactif au moment d'installer l'imprimante

L'installateur est lancé par la commande : 
sh hplip-3.20.11.run
Pour éviter toutes les "required dependencies" manquantes qui empêchent l'installateur de fonctionner, j'ai dû installer par apt-get :
. python3-pip
. python3-pyqt5
. python3-pil
. python-pil

Et puis, pour pip2, j'ai téléchargé une version inférieure à celle des paquets depuis :
bootstrap get-pip

J'ai soumis les commandes : 
sudo python2 get-pip.py
sudo pip install --upgrade pip
Au final, j'ai lancé l'installateur de hplip par la commande : 
sh hplip-3.20.11.run
J'ai ensuite contourné le problème de liaison USB proposé par le §9.1 de la doc hplip :
$ hp-setup -ir
$ sudo apt-get remove ippusbxd
arrêter et relancer l'imprimante et le PC,
$ hp-setup

L'icône "imprimante" fait maintenant fonctionner l'impression dans de nombreux logiciels comme Editeur de texte, LibreOffice Writer, Visionneur de documents, etc...

J'ai enfin permis à la numérisation de fonctionner en installant le hp-plugin.
J'ai essayé d'installer hplip 3.20.11 qui est donné pour supporter ubuntu 20.10
Qu'est-ce que tu as installé exactement et comment ?
J'ai téléchargé hplip-3.20.11.run depuis le site 
https://sourceforge.net/projects/hplip/files/hplip/3.20.11/hplip-3.20.11.run/download?use_mirror=nchc
ou depuis le site 
https://developers.hp.com/hp-linux-imaging-and-printing
J'ai lancé la commande 
sh hplip-3.20.11.run
Et j'ai choisi le mode d'installation "automatique".
Pour ubuntu 20.10, la version d'hplip est 3.20.5 et ton imprimante a besoin d'hplip >= 3.20.5.

Pouquoi veux-tu installer hplip 3.20.11 alors ?
Il est en 20.04 (HPLIP 3.20.3).

xianbroc : Ce n'est pas du tout une bonne idée de mélanger l'installation par paquets (utilisée par Ubuntu) avec une installation par script (qui fait on ne sait quoi) pour les mêmes éléments. Les chances de tout casser sont d'environ 100 %, à moins que ton script génère et installe un paquet deb (format de paquet utilisé sur Ubuntu).

Là, il faudrait idéalement désinstaller la version .run (la façon de le faire dépend entièrement de celle-ci, il n'y a aucune standardisation sur ce genre de méthode), réinstaller HPLIP depuis les dépôts, puis trouver un moyen de le mettre à jour en deb. Ça peut être via un PPA s'il en existe un, via des paquets à installer manuellement (peut-être que HP en fournit), ou éventuellement en voyant s'il est possible de récupérer les paquets des dépôts 20.10 pour les installer (en fonction des dépendances, ça peut être possible ou non).
Ubuntu 20.04 : la doc [doc]hplip[/doc] te suggère de faire une installation "custom".
grigouille a écritPouquoi veux-tu installer hplip 3.20.11 alors ?
En défaveur de la 3.20.5 je lis dans la doc
https://sourceforge.net/p/hplip/news/2020/05/3205-release-notes/
que 
USB print and scan will not work on Vasari and Taccola on Ubuntu 20.04, please refer to link below
http://manpages.ubuntu.com/manpages/cosmic/man8/ippusbxd.8.html
En faveur de la 3.20.11 il est écrit que 
The Automatic Installer is known to work on the following Linux Distributions:

    SUSE Linux (...)
    Ubuntu (12.04, 14.04, 15.10, 16.04, 16.10, 17.04,17.10,18.04,18.10,19.04,19.10,20.04,20.10)
    (...)
Je n'y connais guère en installation de drivers. Je lis d'un côté "will not work" et de l'autre "is known to work". C'est la raison de mon choix.
Mais maintenant que des personnes compétentes sont prêtes à m'épauler, je choisis de suivre leurs conseils et de réparer mes errements ou mes erreurs.
Je pars donc vers la 3.20.5
abelthorne a écritCe n'est pas du tout une bonne idée de mélanger l'installation par paquets (utilisée par Ubuntu) avec une installation par script
Merci pour ce conseil d'ordre général. Je m'en souviendrai et veillerai à l'appliquer.
abelthorne a écritil faudrait idéalement désinstaller la version .run
J'ai lancé la commande suivante : 
sudo python3 ./uninstall.py
qui a répondu 
error: HPLIP is not installed.
Alors j'espère que l'épisode 3.20.11 n'aura pas laissé de traces indélébiles.
Et je m'apprête à rm le hplip-3.20.11.run ainsi que le sous-répertoire qui a été généré. Correct ?

Ensuite, pour suivre le conseil de grigouille, je me lancerai dans l'installation "custom" du paquet hplip-3.20.5
Concernant la désinstallation, je ne saurais pas te dire si tu as tapé la commande correcte. Ça me semble un peu bizarre qu'il ne trouve pas HPLIP alors qu'il est censé avoir été installé par le .run. Pas sûr que ce soit la bonne commande.

L'installation custom de la 3.20.5, ça va être kif-kif, ça reste une installation manuelle.

Personnellement, je tenterais plutôt une installation des paquets en version groovy (20.10) si c'est possible depuis packages.ubuntu.com, il faudrait voir les dépendances (il y a au moins 5 paquets concernés).
Installe la dernière version d'hplip en mode custom. Lis la doc [doc]hplip[/doc].
abelthorne a écritÇa me semble un peu bizarre qu'il ne trouve pas HPLIP alors qu'il est censé avoir été installé par le .run.
L'installation n'a pas été jusqu'au bout : le code est sorti en erreur. Les dernières lignes étaient : 
RE-CHECKING DEPENDENCIES
------------------------
error: A required dependency 'pyqt5 (PyQt 5- Qt interface for Python (for Qt version 4.x))' is still missing.
error: Installation cannot continue without this dependency.
error: Please manually install this dependency and re-run this installer.
J'ai l'impression qu'il n'y a donc rien à désinstaller. Vrai ?
Effectivement. Il faudrait installer python3-pyqt5.

Après, c'est toi qui vois mais si tu veux faire une installation manuelle, il faudrait supprimer les paquets HPLIP d'abord. Il reste hplip-data, tandis que hplip et hplip-gui ont des restes de fichiers de config.
Selon grigouille, la 3.20.5 pourrait suffire. Alors j'ai téléchargé hplip-3.20.5.run
Et je l'ai lancé. Résultat : beaucoup de "failed to install" et au final un "error hp-systray"
Alors j'ai suivi le dernier post de grigouille
grigouille a écritInstalle la dernière version d'hplip en mode custom
OK. Je clique, je tombe sur la 3.20.11
Et je l'installe.

warning: GUI Modules PyQt4 and PyQt5 are not installed
error: hp-systray requires Qt4 GUI and DBus support. Exiting.
Beaucoup de "failed to install" et au final un "error hp-systray". Je suis un peu perdu...
Manifestement, tous les "failed to install" viennent d'éléments qu'il essaie d'installer via pip2. Est-ce que ce dernier est installé ? Cela dit, ce sont peut-être des fonctionnalités optionnelles qui n'empêchent pas l'installation du bouzin.

À la fin, il te dit qu'il n'arrive pas à lancer hp-systray (vraisemblablement le soft qui affiche l'icône dans le systray, la zone de notification) parce qu'il manque les (ou un ?) module(s) PyQt4 et PyQt5. Tout ce qui est Qt4 a été supprimé des dépôts Ubuntu 20.04 mais est-ce que tu as installé python3-pyqt5 comme indiqué dans mon précédent message ?

warning: GUI Modules PyQt4 and PyQt5 are not installed
error: hp-systray requires Qt4 GUI and DBus support. Exiting.
Attention à un détail : il essaie d'installer les éléments avec pip2, le paquet python3-pip concerne a priori pip tout court. Pas sûr que pip2 soit dans les dépôts Ubuntu, il va peut-être falloir l'installer autrement (PPA, installation manuelle...).

Concernant hp-systray, soit il manque d'autres paquets en plus de python3-pyqt5 en rapport avec, soit il veut aussi PyQt4. Ce serait étonnant : comme il parle des deux, je suppose qu'il se contente de l'un ou l'autre, mais si il veut forcément avoir PyQt4 installé, ça va être problématique : il n'y a plus du tout de Qt4 dans les dépôts Ubuntu.
J'ai téléchargé une version inférieure depuis :
https://bootstrap.pypa.io/2.6/get-pip.py.

sudo python2 get-pip.py
