Please ensure your Printer has the latest Firmware. Link: https://support.hp.com/in-en/document/c02919168

Resetting the printer network settings, reconnecting the printer back to the network and adding compatible driver may resolve the issue. Let's try these steps:

1. Unplug your modem/router and leave it powered off.
2. Restart your printer, from the printer control panel, touch "Setup". Touch 'Network Setup", touch "Restore Network Settings".
3. Power off your printer
4. Reconnect your modem/router and wait for it to re-establish its internet connection.
5. Power on your printer.
6. Run Wireless setup wizard on the printer to connect it back to your network.

Once the printer is connected, use the steps below to remove the existing printer driver and add a compatible driver:

1. Click the Apple menu, click System Preferences, and then click Print & Scan or Printers & Scanners.
2. Check if your printer name displays in the Printers list, If your printer is listed, click the printer name, click the minus sign to delete the printer.
3. If you see multiple printer queues for the same printer, remove all extra printers by selecting them one at a time, and then clicking the minus button  at the bottom of the list.
4. Click the plus sign , click Add Printer or Scanner, click the printer name.
5. Click the Use or Print Using menu, select AirPrint in the pop-up menu. Then click Add.
6. Try to print.
