Hi @Mica84,

I'd like to help!

I understand you are facing a printer offline issue.

To assist better -

1. What device are you using the printer with, a Windows computer, Mac, Android, or an iPhone? 
2.  I would like to know, is your router set to work on a 2.4 GHz network or 5 GHz network band?
3. Are you trying to connect your printer to your home network or public network?
4. What is the status of the wireless light on the printer, steady or blinking?

Keep me posted.

 The printer supports connections using 2.4 GHz or 5 GHz.

Make sure both printer and computer are on the same network.

Try the below suggestions -

 Use HP Print and Scan Doctor to check connectivity

Download a special version of HP Print and Scan Doctor specifically created to help with printer offline conditions.

1. Download HP Print and Scan Doctor.
2. Run HPPSdr.exe from the download location on your computer.
3. Once HP Print and Scan Doctor opens, click Start, and then select your printer.
   • If your printer in not in the list, turn it off and on, and then click Retry.
   • If there is a connection problem, follow the instructions in HP Print and Scan Doctor.
4. If a screen prompts you to turn on printer updates, click Yes.
5. If a screen prompts you to make your printer the default printer, click Yes.

Set a manual IP-

To set a manual IP and try the steps below -

--->Touch on the wifi icon ((i)) on the printer, and take down the IP address 

--->Open a web browser (ex Chrome or Mozilla) and type in the printer's IP
