Ich habe im CUPS-Log die Fehlermeldung "Unable to resolve URI". Dazu
meint ein Apple-Mitarbeiter in cups.general, dass das bedeutet, dass
der Servicename den ich in der Device-URI verwendet habe nicht (mehr)
existiert.

Dann meinte er noch, ich könnte

    dns-sd -L C510-Sch8 _pdl-datastream._tcp

verwenden um den Servicenamen zu prüfen und

    dns-sd -B _pdl-datastream._tcp

zum manuellen Browsen benutzen.

In der Ausgabe von avahi-discover taucht der Drucker nicht auf, und
zwar auf keinem der vorhandenen Arbeitsplatzrechner.

Beim Einschalten des Druckers sehe ich auf dem WLAN aber mDNS-Traffic:

Also habe ich gar kein CUPS-Problem, sondern ein Avahi-Problem?
