FIX Encryption Credentials Have Expired on Mac (Printer Issue)

how to fix Encryption Credentials have expired on Mac printers

Encryption Credentials Have Expired is an alert in Mac OS X that informs about Embedded Web Server (EWS) expired certificates which are rejected by the operating system. As a result, the users are unable to print any documents using their HP, DELL, Canon, Epson or other manufacturer printers, with a message “This printer no longer accepts encrypted jobs”. The certificates are required to ensure connection security when using Secure Internet Printing Protocol (IPPs) and Apple’s technology AirPrint. Moreover, users might start getting “* will damage your computer” alerts, which appear because the computer system cannot recognise the printer driver software as secure.
