These are, however, the files from the working (i-e- printing) system, with avahi.
Notice the protocol on those URLs? dnssd = DNS Service Discovery. Which is what avahi does. Therefore, without avahi, it's no surprise your system can't find the printers. By contrast, Nikolaus has:
DeviceURI ipp://drucker/printers/MFCJ5320DW
which is a different non-avahi protocol. I have:
DeviceURI socket://192.168.1.104
which again is not avahi-dependent.
Your setup, while not incorrect in the strict sense, is relying on automagic that's difficult to fix when it breaks.
