Since I updated my AT&T Uverse router last month, my printer says I am off line. I cannot find a way to update the printer. All my devices are set to the new router & key and they all work. Any suggestions?

Welcome to the HP support community.

I understand that you are getting printer offline error, I am glad to assist you.

The printer supports the 802.11n 2.4 GHz frequency band, make sure the router bandwidth is set to 2.4GHz.

And follow these steps to fix the issue.

Use HP Print and Scan Doctor to fix connectivity and printing issues.

Download HP Print and Scan Doctor.

1. Run HPPSdr.exe from the download location on your computer.

2. Once HP Print and Scan Doctor opens, click Start, and then select your printer.

   • If your printer is 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.

3. If a screen prompts you to turn on printer updates, click Yes.

4. If a screen prompts you to make your printer the default printer, click Yes.

5. Try to print.

Assign a manual IP address to manually connect the printer.

Find the printer IP address to assign it manually.

1. 1. From the Home screen, touch (Wireless) and then touch (Settings).

2. 2. Touch Print Report and then touch Network Configuration Page.

Setting a Static IP Address

Once you know your printer’s IP address from the page you printed, entering it is pretty easy. Here’s what you do:

1. Run your Web browser.
2. In the Web browser’s address bar, type the IP address of your printer and press Enter. Assuming you entered the right address, the HP printer control panel should appear.
3. Click the Networking tab.
4. Under Connections, click Wireless.
5. Under IP Address Configuration, click Manual IP.
6. Enter the IP address, subnet mask, and default gateway in the appropriate boxes.
7. Click Apply.
