Notebook Samsung R730. Ubuntu 18.04.3 LTS / 64-bit

Fritzbox 6490. Cabel.

Printer: Brother MFC7360N

Problem: existing wireless printing switched off due to own error.

Error message: Not connected.

Question: Do I have to connect the notebook directly to the computer to make settings.

Did you connect the printer to the fritzbox with the cable and registered and searched for the printer on the laptop and also registered?
