@spn1 Welcome to HP Community!
Let's start off by performing a Hard reset on the printer.
Please 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 the warm-up period finishes and the printer is idle.
Let's perform a clean install to try and fix this issue. Here are the steps:
First, unplug the USB cable from the printer if present.
Go to Control panel – Programs and feature – Select all the HP Deskjet printer entries and uninstall them.
Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
Restart your computer.
Click the bottom-left Start button on desktop, type device manager in the search box and tap Device Manager on the menu.
Once in device manager, click on the view tab in the top & choose “Show hidden devices”.
Then from the device manager list, check the entries under “Printer” – If there are any entries, please right click and choose “uninstall” – In the confirm device un-install pop-up, make sure you select the box which says “Delete the driver software for this device".
Also, check the entries under "printer queue" and "imaging devices" and repeat the same exercise. Delete any printer entry or any entry which says “Unknown device”.
Once done, close device-manger. Then press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" (there is a space between .exe & /) and press enter.
Under print server properties, go to drivers - remove any entry there as well.
Again, go running window, type – “c:/programdata” – Go to the Hewlett Packard folder, remove any printer related folders & files.
Open run again, type “%temp%” and press enter to get the temporary files. Delete all the files here. Skip the items which cannot be deleted.
Now restart your computer again.
Open the Run window again, type “services.msc” and press ok to get services window.
Scroll down to “Remote Procedure Call (RPC)” – right-click and go to properties. Make sure the service is started and the startup type is “Automatic”.
Now scroll up and go to “Function Discovery Provider Host” – right-click and select properties – Change the startup type to “manual” and start the service.
Repeat the same exercise on “Function Discovery Resource Publication” as well.
Click on https://ftp.hp.com/pub/softlib/software13/COL63216/al-152104-1/DJ4720_Full_WebPack_40.11.1124.exe and install the software.
Connect the USB cable only when prompted.
If the issue persists, I would suggest here is to Uninstall the printer drivers and then try installing the Windows built-in drivers for the printer.
Simply turn on the printer and connect the USB cable from the printer to the PC. The drivers will be installed in 2-3 minutes. Go to Control panel - Devices and printers to check the printer entry and make it as the default printer if needed.
