Probably you did already this test (connection with printer not needed):
1) control panel; devices and printers; doubleclick on the default printer; doubleclick see wat is printing; a window appears. Do a printjob; anything appearing in this window?
If not, then there is a problem with spooling. Then:
2) Go to computer management; services and applications; services; Print Spooler.
Print Spooler should be running and automatic.
I am convinced that the problem arises from some faulty interaction between driver and W10. Let's assume that both are ok. Then the only possibility I see is that during the upgrade from W7 to W10 some old driver remains are still lingering in the registry.
So my suggestion is: uninstall the driver, do a manual cleaning of the registry on 8620 residues, do a restart after unchecking the fast boot option in power management, and install the appropriate driver.
Good luck.
With fast boot, turning off the PC "remembers" some settings etc. After changing things you may wish a "fresh start", so uncheck it. When you have a SSD, fast boot does not help much in improving start-up times:
settings; System; Power & sleep; Additional power settings; Choose what power button does; Change settings currently unavailable; uncheck Turn on fast start-up.
Before changing the registry, create a restore point. When you never made changes in the registry, just mention that (for further instructions) and be carefull.
*UPDATE: I am able to scan FROM the HP 8620 to the W10 PC. Still not able to print. I have not had an opportunity to try @play2mefish suggestions yet.
That is pitty. Even a register cleaning was not the solution?
What surprises me is that with an internet search your problem is not really a hot issue. And also HP cannot give the answer.
Although I donot think it will provide a solution (and maybe you did this already) I advise to define two printers. Add printer and call this printer for instance 8620 USB and add another printer called for instance 8620 Network. Both drivers you may now adjust independently. And you prevent, when trying to print via USB, that by accident the driver for network printing is activated.
