Resetting the certificate is the preferred method because selecting the "Airprint" option sends your print data unencrypted. if resetting the certificate does not work, please try adding the "Airprint" driver following the directions from the below post. Note do not select the "Secure Airprint" option as this will cause the expired credentials error to appear.
