@injector, Welcome to the HP Support Community!
There is no driver available for this model printer on the HP Support site to work on macOS 10.15. Also, this printer is not AirPrint compatible.
However, Gutenprint (formerly called Gimp-Print) provides open-source basic print drivers for many printers that would otherwise not be supported in Mac OS X. To see if your printer is supported, go to Gutenprint drivers for more information.
NOTE: Gutenprint drivers are not supported by HP or Apple.
Hope this helps! Keep me posted.
