Volgens de info op deze website zou de HP PSC 750 goed werken onder Linux. Voor het printen is dat inderdaad het geval, maar niet voor het scannen.

Sane 1.09 backends en - frontends heb ik al geinstalleerd. Eveneens geinstalleerd hpijs 1.3

Deze test is in orde.

Sane kan dus geen scanner vinden. (Ook niet als root.)

Ik heb via Yast2 > Hardware > Printer & scanner de HP PSC 700 series geselecteerd.
De printer module wordt automatisch geladen. De scanner module niet.
Dit staat overigens in /etc/modules.conf
