I’ve installed now the packet “cnijfilter2”, used the driver mentioned on the Canon Website.
It didn’t really work.
Than I tried:
lpadmin -p printername -E -v ipp://192.xxx.xxx.xxx/ipp/print -m everywhere
And it worked, the printer is now “installed” and I can use it.
Well, I’m not sure why I have to go this way 
I did it on another (Manjaro) installation a few months ago, only with installing the cnijfilter driver and selecting from the printer menue.
