Hello Smithy, thanks for the reply. I already connected the printer with an ethernet cable, still it does not show the MAC address. In our company network an IP address is only given when the MAC address is registered beforehand. Therefor, the printer is not showing any MAC address when going to connection info. (The picture was made with an ethernet cable plugged in)
Anyway, I am sure we won't be the only one facing such problems, since many company networks are restricted in that way :(.
Any other suggestions?
Thank you and looking forward to an answer.
Best Regards,
Niklas
