ENWW Using the Embedded Web Server 144
Printer Password Synchronization. Many EIO printers 
provide password-protected access to printer configuration and 
status settings. The password is set through security Web pages 
provided by the printer. For these printers, the administrator 
password for the printer and the Jetdirect print server are 
synchronized so that the same password is used to access both 
printer and networking configuration pages. For printers that 
support password synchronization, the same password is used 
regardless of the embedded Web page (printer Security page or 
networking Admin. Account page) in which the password was set.
If password synchronization is lost on these printers, recovery may 
require one of the following procedures: 
● Restore both the printer and the Jetdirect print server to 
factory-default states (for example, through a cold-reset), and 
then reconfigure your settings.
● Manually set the same administrator password using both the 
printer Security page and the networking Admin. Account 
page.
Certificates 
(Full-featured HP Jetdirect print servers only) This tab provides 
access to installation, configuration and management services for 
X.509 digital certificates. A digital certificate is an electronic 
message typically containing, among other things, a key (a short 
string used for encryption and decryption) and a digital signature. 
Certificates may be issued and signed by a trusted third party 
(commonly called a Certificate Authority, or CA), which may exist 
internal or external to the organization. Or certificates may be 
“self-signed”, which is similar to validating your own identity. 
Note While self-signed certificates are permitted and 
allow data encryption, they do not ensure valid 
authentication.
The Certificates page provides the status of the certificates 
installed on the HP Jetdirect print server:
● Jetdirect certificate. The Jetdirect certificate is used to 
validate the identity of the Jetdirect device to clients and to 
network authentication servers.
