@Graybeard1960,

Thank you for posting your query on HP Community,

If the printer is connected using Wireless and if the Wireless light on the printer is steady blue in this scenario, I would suggest here is to disable IPV6 and update the printer firmware. 

Perform a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove USB cable, if present.

Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till warm-up period finishes and the printer is idle.

Step 2: Turn off IPv6

Use the control panel to turn off the IPv6 setting.

1. From the home screen on the printer control panel, swipe the display to the left, and then touch Setup.

2. Touch Network Setup, and then touch Advanced Settings.

3. Turn off IPv6, and then touch Yes to confirm.

Alternatively, you can try to disabling IPV6 from the software and assign Manual IP:

Obtain the IP address of the printer – You can touch the “wireless” icon on the printer control panel to get the IP address.

Type the IP address on your web browser to obtain the printer EWS page on your computer.

Go to "Network" tab - General - Select "Network protocols" - Select "Enable IPv4 only" (or similar) - Apply the settings.

Go to the “Network” tab – Click on “Wireless (802.11) – Then click on “Network address (IPv4)

Click on the radio button which says “Manual IP” and then click “Suggest a manual IP address” to give a manual IP address to your printer.

Click on radio button which says “Manual DNS Server” and under manual preferred type 8.8.8.8 and under manual alternate type 8.8.4.4 (This is Google DNS server address)

Restart the printer and the router once done.

You can also update the Firmware, you can directly update the printer firmware from the printer control panel or download the software from our HP support website, 

If your printer connected wirelessly, make sure to temporary connect the device with USB and then follow the link to install the latest firmware update on your printer from our HP support website. Alternatively you can also try to update the printer firmware directly from the printer control panel.

@Graybeard1960,

I recommend you run the HP print and scan doctor and check if it helps.

Please download and run the HP Print And Scan Doctor from this Link: https://ftp.hp.com/pub/printers/hppsdr/HPPSdr.exe

Run PSDR v5.0.2 

Once the PSDR detects the Printer, it will show up the IP address and Software Status. 

Select the correct Printer and click on Next. 

PSDR will check if the Printer is on the Network and communication between the PC and the Printer. Once the connection check is done, click on Fix Printing 

Once PSDR goes through all checks and automatic fixes, click on Print a test page. 

Regardless if PSDR printed the test page or not, click on “NO PRINT” 

PSDR will then notify you that there is an update available, click on continue, and PSDR will apply the patch and ask for a reboot. 

Post restart the PSDR will run automatically to check for more issue.  If no issue found close PSDR. 

Also, try using the HP Smart App and let me know if that helps. Link: https://www.microsoft.com/en-us/p/hp-smart/9wzdncrfhwlh
