Merci pour votre suggestion.
Une remarque cependant : Avant sous F28 tout fonctionnait
Je n'ai découvert le problème qu'après l'upgrade vers F29.
J'ai donc suvi la procédure HP recommandée, voici ci-après ce que ça donne.
J'ai bien noté que: " fedora-29 version is not supported ( by HPLIP ), so all dependencies MAY not be installed. "
Bref ça fonctionne mais c'est LOURD en dépendances ( et jamais je n'avais eu besoin de tout ça avant ).
Encore merci
Bye
