Using the Embedded Web Server 126

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 communication 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 Jetdirect embedded 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. 

The minimum encryption strength that will be allowed must be 
specified when using a Jetdirect certificate. You may select Low 
(default), Medium, or High encryption strength. For example, 
selecting Low will allow medium or high encryption levels to be 
used whereas selecting High will only allow high encryption levels.

For each encryption strength, ciphers are specified to identify the 
weakest cipher allowed. Early browsers may only support 40-bit 
(Low) encryption levels.
