XSANE does not see my scanner (part of a Lexmark all-in-one S350). It worked fine,using Ubuntu 10.04. Printing works fine. The all-in-one printer is wireless. The router sees it. I can ping it. I can view it on the LAN via a browser and the local IP address.
I did get a new computer, but I think the difference is that XSANE that installs with Synaptic is now 0.968. The previous setup used 0.966.
