Hallo zusammen,
mein
HP Color LaserJet CP1514n - Drucker ist per USB und per Netzwerkkabel an meinem Rechner angeschlossen.
HPLIP ist installiert. Der Drucker ist via IP-Adresse erreichbar.
Leider druckt er noch nicht (weder via USB noch als Netzwerkdrucker).
Ich habe den Drucker als Netzwerkdrucker und als USB-Drucker installiert. Die Druckaufträge und Testseiten werden an den Drucker gesandt, aber nicht ausgedruckt.
Ich hoffe, mir kann jemand anhand des nachfolgenden Codes weiterhelfen:

error:  HPLIP cannot detect printers in your network.  This may be due to existing firewall settings blocking the required ports.
                When you are in a trusted network environment, you may open the ports for network services like mdns and slp in the firewall. For detailed steps follow the link.

Falls dies nicht genügen sollte, könnten wir uns auch die Log-Datei ansehen. Wo finde ich die?

Vielen Dank für weiterführende Hinweise.
