SSL/TLS Communication with the Printer
When the server certificate is set using SSL/TLS (Secure Sockets Layer/Transport Layer Security) communication to
the printer, you can encrypt the communication path between computers. Do this if you want to prevent remote and
unauthorized access.
About Digital Certification
❏ Certificate signed by a CA
A certificate signed by a CA (Certificate Authority) must be obtained from a certificate authority. You can ensure
secure communications by using a CA-signed certificate. You can use a CA-signed certificate for each security
feature.
❏ CA certificate
A CA certificate indicates that a third party has verified the identity of a server. This is a key component in a
web-of-trust style of security. You need to obtain a CA certificate for server authentication from a CA that issues
it.
❏ Self-signed certificate
Self-signed certificate is a certificate that the printer issues and signs itself. This certificate is unreliable and cannot
avoid spoofing. If you use this certificate for an SSL/TLS certificate, a security alert may be displayed on a browser.
You can use this certificate only for an SSL/TLS communication.
