OK, I have disconnected the USB cable at both sides. Interesting. I get 
exactly the same result:

bas at Viaconsensus-iter:~$ scanimage -L
device `pixma:G3000_192.168.2.12' is a CANON Canon PIXMA G4000 Series 
multi-function peripheral

The result I get from that command looks good:

I did manage to print two things without usb cable, so via the wireless 
connection: one text document and one photo. The text document came out 
smoothly and quickly. The photo also came out correctly - however, the 
printing process was slow.

 From the command "avahi-browse -rt _uscan._tcp", I get this no-result:

bas at Viaconsensus-iter:~$ avahi-browse -rt _uscan._tcp
bas at Viaconsensus-iter:~$

In other words - the command avahi-browse -rt _uscan._tcp does not 
deliver any result.

When trying Skanlite, the device is being seen again as "CANON Canon 
G4000 Series" - so, also with the USB cable DISconnected. However, when 
hitting the scan-button, I get the same graphical feedback as yesterday:

"(...)

The above test is another indication that the wireless connection 
apparently functions. However .... do I need to install some extra piece 
of software - from Canon or our own repos or elsewhere? Or is there 
anything else I need to do?

Summary:

* the wireless connection functions;

* printing also functions - however with hiccups in the case of a photo;

* scanning does not function yet.

At this point, I finish this message.

Have a good Sunday. Yours.

Bas.
