I did purchase the HP Desktop 2720, an all-in-one printer/scanner/copier, for which I found a solution for a proper printer driver. However I was unable to install the driver for the scanner. This one is present in the newest version of hplip, however I was unable to build that package for openSUSE.
With some luck you don't need the proprietary, closed source crap (while hplip itself is open, it loads some binary modules for "advanced" functionality, e.g. scanning). Modern MFPs support eSCL aka "AirScan". If your printer does, it should announce itself using DNS-SD, type "_uscan". You can check this with $> avahi-browse _uscan._tcp => + wlp6s0 IPv4 Color LaserJet Pro M479 _uscan._tcp local If it appears, you just have to enable the "escl" sane backend. $> sudo zypper install sane-backends $> echo "escl" | sudo tee /etc/sane.d/dll.d/escl $> cat /etc/sane.d/dll.d/escl => escl $> scanimage -L => device `escl:https://192.168.180.47:443' is a ESCL Color LaserJet Pro M479 flatbed scanner Kind regards, Stefan -- Stefan Brüns / Bergstraße 21 / 52062 Aachen home: +49 241 53809034 mobile: +49 151 50412019
