Network not recognizing OfficeJet Pro 8100

[Al_8100]

Had networked this wireless Officejet Pro 1800 (OJP1800) previously with pc's, cell's, everything working. 

  1) - Got new network provider with everything BUT OJP1800 recognized on network to print. 

  2) - Network sees OJP1800 on one pc, but without correct description "(Officejet Pro 8100 (66985E)" and error on printing test page.

  3) - On other pc, I deleted the OJP8100 thinking network would find correct device, but cannot find OJP8100 in any form.

  4) - OJP8100 existed on old network for 3 yrs with no ethernet cat-5 cable to printer, is wireless to network.

  5) - have tried HP App on cell, to no avail.
  6) - Windows 11 on pcs, not sure on printer.

  7) - Let Windows manage printers (ON) ; Download Drivers and Divice Software (ON) ;  Windows Protected Print Mode (OFF)

Please suggest resolving network overlooking OJP8100.   Thank you!

Hi @Al_8100 

Welcome to the HP Support Community.

Thank you for posting your query.

I understand that you have network recognition issues with your OfficeJet Pro 8100 after changing network providers,I would request you to please follow the steps:

Verify Network Connection

• On the printer’s control panel, navigate to Wireless Settings → Wireless Setup Wizard.
• Select your new Wi‑Fi network and enter the password.
• Make sure you are connected with 2.4GHz network.
• Print a Network Configuration Page (from the printer’s Reports menu) to confirm the printer is connected and shows the correct SSID and IP address.

Update Printer IP Address

• On your PC, press Windows + R, type control printers, and press Enter.
• Right‑click your OfficeJet Pro 8100 → Printer Properties → Ports tab.
• Check the IP address listed.
• If it doesn’t match the printer’s new IP (from the Network Configuration Page), click Configure Port and update it.
• Alternatively, remove the old port and create a new Standard TCP/IP Port with the correct IP.

Reinstall Printer Drivers

• Go to HP Support → Drivers & Downloads → OfficeJet Pro 8100. https://support.hp.com/au-en/products

Reset Printer Network Settings

• On the printer’s control panel, go to Setup → Network Settings → Restore Network Defaults.
• Confirm the reset.
• Reconnect the printer to your new Wi‑Fi network using the Wireless Setup Wizard.
