HP Designjet Printer Series Security Settings 3.10 CA/JD Certificates You can request, install, and manage digital certificates on the HP JetDirect print server. Certificates are used to identify the JetDirect print server both as a valid Web server for network clients, and as a valid client requesting access on a secure network. By default, the JetDirect print server contains a self-signed preinstalled certificate. 3.11 Hide IP from front panel Some printers includes an option in the Service Menu, accessible with the help of an HP Support agent only, that allows you to hide all IP information from the printer's front panel. 3.12 Encrypt web communications You can securely manage the network device using a Web browser and the HTTPS protocol. To authenticate the HP JetDirect Web Server when HTTPS is used, you may configure a certificate, or you may use the pre-installed, selfsigned X.509 Certificate. The encryption strength specifies what ciphers the web server will use for secure communications. Supported cipher suites are DES, RC4, 3DES. By enabling encryption, the web server encrypts all web communication, forcing all connections to use HTTPS. Enabling encryption can also be configured to allow both HTTP (unencrypted) and HTTPS connections. In secure environments, you should choose to encrypt all web communications. Otherwise, sensitive management data (Administrator Password, SNMP Community Names, and secret keys) may be compromised. 21
