HTTP, HTTPS, and SSL/TLS
HTTP (Hyper Text Transfer Protocol) is used to communicate across the Internet between the printer
Web server and the Web browser (clients). Because the data is transmitted in plain text and passwords
are only slightly encrypted, it is not secure; the data can be read or intercepted by other people.

HTTPS (Secure Hyper Text Transfer Protocol) is a secure version of HTTP. HTTPS provides
authentication and encrypted communication to preserve the confidentiality of your data. Instead of
using plain text, HTTPS uses either the SSL (Secure Socket Layer) protocol or the TLS (Transport Layer
Security) protocol to encrypt data, thus ensuring reasonable protection from eavesdroppers and man-
in-the-middle attacks.
