@Fary1921 Welcome to HP Forums!

I suggest using the HP Print and Scan doctor to identify and resolve this issue:

Install HP Print and Scan Doctor on the computer connected to your printer.

1. Make sure your printer is turned on and connected to the computer.

2. Download HP Print and Scan Doctor, and then follow the on-screen prompts to install and open the tool.

3. On the Welcome screen, click Start to view a list of available printers.

4. Select your printer in the list, and then click Next.

   If your printer is not listed or a connection problem is detected, click My product is not listed or select your connection type, follow the on-screen instructions, and then click Retry.
    

   
    

5. Click either Fix Printing or Fix Scanning.

   If you are prompted to install the printer software, follow the on-screen instructions. The software can resolve many printer issues.
    

   
    

6. Review the list of test results, and then resolve any issues found.

   • If you see a checkmark, the printer passed the test.

   • If you see a wrench, HP Print and Scan Doctor found an issue and repaired it.

   • If you see an exclamation point, the test failed and required user action, but the step was skipped.

   • If you see an X, follow the on-screen instructions to resolve the issue.
      

   

If the issue persists, please try the below steps:

Please follow the below steps to assign a manual/static IP to resolve your concern:

-Verify in the printer that 'Auto Off/Sleep' is disabled. Use the Embedded Web Server (EWS) by going to the printers IP address in your browsers address bar, click Settings Tab/Auto-Off. --Or use the Printer Assistant, Printer Home Page (EWS). Also, check your Printers Properties.

-If the printer supports and has IPv6 enabled, turn off IPv6 in the printer.

-If needed and you assigned a static IP address, try using 8.8.8.8 for the Preferred DNS server and 8.8.4.4 at the Alternate DNS server. 

-Verify the printer is on the latest firmware by checking with the HP Support site.

In the router: (Refer to your router manual for information) 

Use a fixed wireless channel like 1, 6 or 11, never 'auto', try channel 1 first then the rest. 

Set router to 20Mhz only, or 145Mbps depending on the router. 

Always use WPA2-AES (Personal) encryption, but you can try `mixed' mode. 

Disable WPS and never use it and disable UPnP for the routers security. Nobody can hack your system now and helps with wireless connectivity (if you want to know why search the web).

If you have a dual-band router (2.4Ghz and 5.0Ghz bands), make sure the SSID's are NOT the same, they must be different for all bands, even for any Guest networks.

SSID broadcast must be enabled.

Save all settings. Power off both, wait 2 mins. Power on the router and wait 2 mins. 

Power on the printer and verify it reconnects to the router

You can also refer to the below video for the same. 

Note that, in the video, the interface shown is the Windows interface, but the steps are the same as it done using a web browser. 

And the article may have the title of another printer, but the steps are bound to help resolve your concern as well.
