hp print not working

This is probably going to involve HP, unless you have acquired a printer with features that avoid the need for the HP printer drivers.

Please post the specific HP printer model— the full printer model name, as HP has lots of printers, and some of which share the same numbers—and from that information we can see what options might be available.

Good luck with HP helping you. They are the most useless company I have had to deal with and there are some bad ones out there. My HP printer 1510 won't work now because I installed Big Sur on my Mac some time ago now. If Hp aren't going to release new drivers for their printers to work with updates in Apples' Operating Systems they should let people know.

http://www.hp.com/support offers all current drivers by model.

If your model does not have drivers for Catalina Mac OS 10.15 minimum, and doesn't show 11.0 drivers, you likely will have to either look for open source drivers, or see if the built-in open source drivers work.

To access the open source drivers, plug the printer in via USB, or ensure it is on the same secure WiFi, then go to Apple menu -> System Preferences -> Printers, and add the printer by clicking both on the plus button on the bottom of the printer box, and the Option key on the keyboard at the same time. If the printer has open source drivers built-in they will appear in the selection. Otherwise, you'll need to get a printer that supports the system you are running.

This is a result of printer drivers. Contact hp for further assistance. Next, as a user to another.... I recommend you check with the printer manufacturer prior to updating macOS.
