My printer shows the Service Error 49.

I have tried to turn and turn off. It turns on, but displays network error and then it shows the black screen with Service Error 49.

I have literally tried everything possible.

 

I read that somebody recommended updating the firmaware using a USB-stick. I went onto the HP site to download the firmware, but my Macbook does not allow to run it (needed to install it), as iOS cannot check it for malicious content.

I also read that it could be the network card.

Anybody has any idea of what to do?

Thanks in advance.
