ENWW 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.
