Can't install wireless Officejet Pro 8600 Plus

[Dak2]

I can no longer print on my wireless connected HP Officejet Pro 8600 Plus. It had been working until about 2 weeks ago when it would no longer print. Attempts to reinstall the printer after uninstalling have been unsuccessful. The installation stops with a message that network installation was unsuccessful. I have been installing from the file OJ8600_1315-1.exe and have gone through all the steps in the HP printer installation troubleshooter (HP Installation Failure- Unknown Device.hta), except for getting into the router configuration page (which I can't access). I have also tried installing via the built in Administrator account without success. If I install via the "Add a Printer" in Windows "Devices and Printers" I can get the icon for the printer to appear, but it can't print. If I click on "Customize Your Printer", I get a popup that "The 'HP Officejet Pro 8600' printer driver is not installed on this computer." Attempts to print the test page give a popup "Test page failed to print" and "Access denied". Running the troubleshooter leads only to the suggestion to make it the default printer, which doesn't help. 

It isn't clear why it stopped working 2 weeks ago. Some non-virus malware was found on the computer and removed since then. 

Running "printui /s /t2" shows "HP Officejet Pro 8600 x64 Type3 - User Mode", "HP Officejet Pro 8600 Class Driver x64 Type4 - User Mode" and "Fax - HP Officejet Pro 8600 x64 Type3 - User Mode".

I can get into the printer Network configuration page remotely. It is on channel 11 with signal quality 5. 

Further information about the system:

Windows 10 version 1607 (OS Build 14393.1066).

Using an Actiontec MI424WR router from Verizon.

The Device Manager says that "This device is working properly", hpvl09.inf was installed. Driver Management concluded the process to install driver hpvpl09.inf_amd64_6d04c3df7858e88c\hpvpl09.inf for Device Instance ID SWD\PRINTENUM\WSD-1162FE49-773F-4BE5-BB3F-78A058F1E97E.006B with the following status: 0x0.

Thanks for any suggestions to get the printer working again.
