This app seems to make the assumption that everyone has Internet, EVEN THOUGH the app has an advertised Wi-Fi Direct connection mode that is supposed to allow connection between a cell phone (Samsung S20 w/ Android 12, in my case) and the printer (HP Color Jet Laser Pro MFP M283cdw) *without* the need for Internet. After establishing the required connections between the printer and the phone, all you get is "This printer isn't available". HP knows about the bug, but hasn't fixed it.
