I have an rpiZW attached to my printer..It's as slow as a dog but works. I don't do much printing, months can go by. It's more important for it to now be "wireless". I guess you've had the same thought.
All I have attached is a mini usb <-> usb A adapter straight into the printer cable. I'd expect any usb device to at least show up with 'lsusb' thus my first thought is the HAT. Boot your PC using a live (say linux mint) thumbdrive. Open a terminal, 'lsusb' without printer connected. Plug printer in, 'lsusb' should show an extra entry which ought to correspond to your printer.
If the printer appears, likely the HAT.
If the printer does not appear, investigate (and this would be weird) if the printer is capable of going to sleep in such a way as to disappear off usb. You may be able to tell/change this if you have its drivers installed under win10.
Perhaps 'journalctl -f" on the rpiZW (in conjunction with the dmesg advice) might yield something. I'd not rule out (it being HP) for them to have done something - perhaps the printer is sulking because the HAT manifests as a hub?
