Mgmt. Protocols This link provides access to management communications and other protocols that affect security. Web Mgmt. Use this tab to manage communications with the embedded Web server from Web browsers. This tab appears only for full-featured print servers. Secure, encrypted Web-based communications is provided through the Secure HTTP (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 Internet Printing Protocol (IPP) use, other non-secure communications (HTTP) are redirected to HTTPS. Redirection of your browser to use HTTPS may be transparent depending on your browser's capabilities. HP wireless print servers, by factory default, are configured to require HTTPS communications. HP wired print servers, by factory default, are configured to allow HTTPS or HTTP. Although not recommended, you may choose to accept both HTTPS and HTTP communications that are not secure by disabling (clearing) the Encrypt All Web Communication checkbox. To support the use of HTTPS communications, a Jetdirect certificate must be installed. A factory-default, self-signed certificate is preinstalled for initial use. Click the Configure button to update the preinstalled certificate, or to install a new one. For more information, see Configuring Certificates. Encryption strength must be specified when using a Jetdirect certificate. You may select Low (default), Medium, or High encryption strength. For each encryption strength, ciphers are specified to identify the weakest cipher allowed. Early browsers may only support 40-bit (Low) encryption levels. ENWW Using the Embedded Web Server 151
