Thanks Louis, I'll check that out a bit later today. I'm happy that I have it 
working and posted here to let others know.  I'll follow developments and happy 
to be a tester of the new protocol if and when that occurs. JohnSent from my

would connect to the scanner over ethernet: canon is removing the bjnp/mfnp 
protocols from recent scanner models, See the man-page for sane-pixma in GIT, 
updated yesterday for a description of a method of finding out if you device 
supports one of these protocols.Basically start avahi-discover and look at the 
content of the _scanner._tcp entry for the device. If this does not mention 
port 8610 (mfnp) or 8612 it is likely that the scanner does not one of these 
protocolsLouis
