Hi,

Ensure your printer firmware is up to date by following below utility and check:

https://ftp.hp.com/pub/softlib/software13/printers/en4520new/EN4520_R1827B.dmg

If the same persists, from System Preferences select Printers & Scanners.

Select your listed printer and click the minus sign to remove it.

Click the plus sign to add it and be sure to select the AirPrint option within the Use drop-down menu, then check for any difference.

Please let me know if that helps,

Shlomi

One possibility is that the printer's server certificate has expired. To resolve this issue please follow the directions outlined in the document "'Encryption Credentials Expired' Error Displays".
