Welcome to HP support community.

Which version of Windows version is installed on the computer to which this printer is connected?

Meanwhile:

Use HP Print and Scan Doctor to check connectivity

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 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.

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 manual IP address and that should fix the issue.

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

2. Touch Print Reports. and then touch Display Network &onfiJurDtion or Print Wireless Test Report.

Setting a Static IP Address

Once you know your printer’s IP address, 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.
