[sane-devel] Error during device I/O with network attached HP

Thanks Johannes,

I'll see what information I can get through the HPLIP mailing list.  I saw the 
listing on the support page that claims that the 4100 doesn't have network 
support, and I am confused what that means.  I can ping the printer on the 
network.  I can print to it over the network. I've been doing that for months 

Where does "scanimage -L" get its information from?  Does reply indicate that 
it is connecting to the printer, or just that the driver is installed?  I 
guess it must be the latter since I get the same response with the printer 
turned off.
