Which communications interface are are you using?

USB.

Airprint comes from IPP, which is the current "driverless" network protocol used by

CUPS (from when CUPS was an Apple project).  There are drivers that make USB

look like IPP, but I assume those are printer-specific.  Airprint may diverge from IPP

in the future, but HP's specs say this model works with older macOS versions, so

should support CUPS driverless printing  for ethernet and wifi.

For USB, see https://github.com/OpenPrinting/ipp-usb.  The "Issues" section has

examples of troubleshooting on linux:

So there are, but none of them seems to have much to do with my situation.
