If SSL is enabled for IMAP/ POP on a mail server, you might be unable to configure email printing using the iPrint Console.
To work around this issue, you must manually import the mail server certificate into iPrint using the following procedure:
On the iPrint Advanced server, execute the following command:
keytool -import -alias <alias_name> -keystore /usr/lib64/jvm/jre-1.8.0-ibm/lib/security/cacerts -file <Cert_file_path>
Th default password is “changeit”.
To accept the certificate, restart the Mobile server:
rcnovell-iprint-mobile restart
