Where is WPN ID number on HP ENVY 7858

[KRMDGN1]

My printer indicated it was offline.  I uninstalled and tried to reinstall, but it asks for a WPN ID# on the paperwork (misplaced) or the printing unit.  My question is:  WHERE is the number located?

Welcome to the HP support community.

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 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 and that should fix the issue.

1. Load plain U.S. letter or A4 paper in the input tray.
2. On the printer control panel, swipe down to open the Dashboard, and then touch the Setup icon .
3. Swipe up on the display, and then touch Reports.
4. Touch Network Configuration Page to print the page, which can be up to four pages long.

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.
