Driver is Unavailable for Envy 7855

[Jeff412]

I have been using this printer for several months with no problems. Recently Windows 10 updated and the update said "Unable to complete Update, Undoing Changes". Then on the next update everything appeared worked correctly. However, after the successful update the Envy 7855 gives me a "Driver is Unavailable" message.The printer is online and I can print to it from other computers, just not this one. The installation software sees the printer and appears to install fine. I can get to the printer through the web UI by using the ip address. I can also see the printer through the HP Smart App. I just can't print to it. Currently running Windows 10 64-Bit, Version 1909. Any help would be greatly appreciated.  I have tried the following and nothing has worked so far. 

1. uninstalled and reinstalled printer.

2. Completed all Windows 10 updates.

3. Updated firmware on printer.

4. Unplugged printer and restarted.

5. Tried installing by IP

6. Tried using direct print option. It asks for the the wps code and appears to install, but then says driver is unavailable.

7. Tried installing with Windows Update, but I get an error that says "Printer Driver was not installed. The system cannot find the file specified".

7. Followed these steps listed in another post. Did this three times just in case I missed something.

@Jeff412 That's quite an impressive list of steps you've done, that said, here's what you need to do, next, to resolve the issue:

I recommend you delete the driver at the 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" and "/s") 

8.) Click on the "Drivers" tab 

9.) Look for 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 

Then, Click here to access the HP website, find the drivers compatible with your windows and install it.

If the issue persists, please go ahead and install the windows built-in drivers: 

If a full feature driver from HP is not available for your printer, you must install the built-in print driver. A full feature driver for one or more Windows versions is not available for your printer, either from the CD that shipped with your printer or from the HP website.

   NOTE:

Where is the download button? The HP print driver is built into the Windows operating system or is installed through the Windows Update feature on your computer. You do not need to download anything from a website in order to print, scan, or fax.

See the Frequently asked questions in this document for additional information, including how to scan using this driver.

Thanks for the suggestion, but I had already tried that and it did not work. However, I recently updated Windows 10 to version 2004 and that resolved the issue. Evidently version 1909 was causing the problem. I thought I would post this for others that may be having the same issue.
