Windows 10 slow printing to OfficeJet 4500

[Theoldwizard1]

Recently purchased laptop with a "direct from Microsoft" installation of Windows 10.  I downloaded and installed the latest driver software (V8.0.0) for my OfficeJet 4500 (which still works flawlessly with other Windows 7 computers).

I am printing wirelessly, but it is very slow, even in Fast Draft mode.  One pass of the print head and pause.  Another pass and pause.

Hardware : Ryzen 5 3500U, 16 GB memory, 512 GB M.2 NVMe

Observations using perfmon /res while printing : plenty of free memory (>5 GB), plenty of free CPU (SPLWOW64 is using < 1.0 CPU), very short disk queue length (<0.1), no excessive network usage.

What else should I check ?

HP Print and Scan Doctor FAILED TO PRINT TEST PAGE with a not useful error message

Believe it or not Microsoft Tech support solved the problem !
From a CMD window (running as Administrator)

net stop spooler
DEL /F /S /Q %systemroot%\System32\spool\PRINTERS\*
net start spooler

Not sure why that worked, but it is still working after a reboot.
