I have openSuse 11.4 installed on my main computer with an Epson SX435W printer/scanner installed on a networked print server. This is working fine as a printer but isn’t detected as a scanner.
The drivers, iscan, were downloaded from Avasys and both printer and scanner drivers are installed on both machines. The scanner works locally on the print server. In Yast>>Scanner no scanners are detected by either net or epkowa drivers. Click ‘Other>>Scanning via network’ settings are Server:127.0.0.0/8,192.168.1.3, Client:192.168.1.3,localhost. Click ‘OK’ and no scanners are detected.
The printer server runs Mageia and is accessed by any machine connected to the network. Both printing and scanning are working on the server and printing is OK over the network.
Having read your linked info about firewalls and scanning I think it would be better to carry on as I do now, scan on server then copy files over as the scanner is in the same room. I guess it’s not much more work than scanning over the network.
