I tried to install the printer with Printer Manager without success neither with hp-setup  (see attached images) :
localhost - root [11/Oct/2020:19:45:44 +0200] "OST /admin/ HTTP/1.1" 200 335 CUPS-Add-Modify-Printer server-error-internal-error

It seems there are problems with hpcups driver. I have succeeded by adding the printer via CUPS web interface (http://127.0.0.1:631) using the hpijs driver.
