I've setup my Raspberry Pi B as print server and also wanted to use it for scanning over network.
OS: Raspbian Wheezy (debian-pi/raspbian-ua-netinst) uptodate
Printer/Scanner: HP Deskjet 2050 J510 AiO
I've installed cups and everything it was asking for. Cups picked up the printer and I can print without any issues. I installed sane and it also picked up the scanner of the Deskjet 2050 and I can scan throug the sane commandline tool "scanimage".
When I use SaneTwain/SaneWinDS or XSane for Windows no scanner devices are found through these Sane to Twain bridges although they can connect to the sane server hosted on my Raspberry Pi.
Any idea what's wrong?
