In Ubuntu and Mint I used xsane to connect to my networked (wired ethernet) HP L7680 multifunction printer/scanner.
The default scanning app Skanlite in Kubuntu 12.04 won't find my device.
I like xsane and I am considering installing it, but it will bring in gimp and 62.9 MB of additional stuff.
Can anyone recommend the best way to scan stuff from my networked HP L7680 in Kubuntu 12.04?
