@Rocheacri, Welcome to HP Support Community!

 

To reconfigure the printer, follow the steps from the document HP Printers - No Connection after Router or Wi-Fi Settings Change.

 

Also, if the router is dual band ensure the SSIDs are different for both the networks. To avoid any connection issues, connect the printer and the computer to the same network.

 

For printer offline issues-

 

You may need to instead go into your router settings and try changing the channel manually. Experiment with different channels to see which one works best.

 

Use HP Print and Scan Doctor

Download HP Print and Scan Doctor and run the program. It will automatically diagnose and fix any printer connectivity issues. 

For more information, go to https://support.hp.com/us-en/topic/printscandoctor

 

Update the printer firmware

Download available firmware updates from the HP website

With the printer on and connected to the computer, go to HP Customer Support - Software and Driver Downloads, and then identify your printer. Look for and install any available firmware updates. Refer to the document HP Printers - Updating or Upgrading Printer Firmware

 

Assign manual IP to the printer

The steps on how to set a manual IP address can be found here.

For the DNS servers please use 8.8.8.8 for the Manual Preferred DNS Server and 8.8.4.4 for the Alternate DNS server. These are Google’s public DNS servers

 

If the issue persists, I recommend you delete the driver and root level and retry, follow the steps below: 

  

1) In Windows, search for and open Programs and features 

2) Select your HP Printer 

3) Select Uninstall 

4) In Windows, search for and open Devices and printers 

5) In the Devices and Printers windows look for your HP printer. If you see it listed right-click on it and choose ‘Delete’ or ‘Remove Device’ 

6) Open up the run command with the “Windows key + R” key combo. 

7) Type printui.exe /s and click Ok. (Note: there is a space in between “printui.exe”

8). Click on the “Drivers” tab 

9) Look for the HP Printer driver. If you see it Click on it and click Remove at the bottom 

10) Select Ok 

11) Select Apply and Ok on the Print Server Properties windows 

12) Close Devices and Printers.

 

Use this link to download and install the new driver. Configure the printer.

 

You can also add the printer using IP address-

 

 

1.  Select “Start” and type “printers” in the search box. 

2.  Choose “Printers & scanners“. 

3.   elect “Add a printer or scanner“. 

4.  Wait for the “The printer that I want isn’t listed” option to appear, then select it. 

5.   Select “Add a printer using a TCP/IP address or hostname” , then select “Next“. 

6.   select “TCP/IP Device” in the “Device type” list. 

7.  Type the hostname or the IP address of the printer. Select “Next“. To find the IP address of the printer, touch the Wi-Fi icon on the printer's control panel.  

8.  Windows should find the printer if the printer is on and configured correctly. You may have to specify more information. If prompted, Select the type of network adapter installed in the printer in the “Device Type” drop-down list. You can also click “Custom” to specify custom settings for the network printer. Select “Next“.

 

Try printing.

 

Hope this helps! Keep me posted.
