Secure, encrypted Web-based communication is provided through the HTTPS protocol. If configured to require HTTPS, the embedded Web server routes HTTPS communications through port 443, the well known port for HTTPS traffic. Although ports 80, 280, or 631 continue for IPP use, other non-secure communications, such as HTTP, are redirected to HTTPS. Redirection of your browser to use HTTPS can be transparent depending on your browser’s capabilities.
IPP is not supported on value-based print servers.
To support the use of HTTPS communications, you must install an HP Jetdirect certificate. A factory default, self-signed certificate is installed for initial use. Click the Configure button to update the installed certificate, or to install a new one. For more information, see Configure certificates.
The minimum encryption strength allowed must be specified when using an HP Jetdirect certificate. Select Low (default), Medium, or High encryption strength. For example, select Low to allow use of medium or high encryption levels. Select High to use only high encryption levels.
Cipher suites support different levels of encryption strength. The cipher suites currently supported for encryption and decryption are data encryption standard (DES, 56-bit), RC4 (40-bit or 128-bit), and 3DES (168-bit).
