7640 printer visible in HP smart (but offline) and invisible in windows

[mach26]

I have a 7640 printer ethernet wired to a router and several computers connected wirelessly or via ethernet to the router. One laptop running Win 10 64bit stopped seeing the printer. There was a document stuck in the print queue, now removed. HP smart can see the printer but reports it offline when it is not. Windows however cannot detect the printer at all even though the printer works fine with the other attached computers. I tried reinstalling the software on the lone computer (laptop) but still get the same problem. All other services seem to be fine

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

13.)  Open up the run command with the "Windows key + R" key combo.
