Printer Password Synchronization; Certificates; Jetdirect Certificate - HP jetdirect 175x Administrator's Manual

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:
G
Restore both the printer and the Jetdirect print server to
factory-default states (for example, through a cold-reset), and
then reconfigure your settings.
G
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
The Certificates page provides the status of the certificates
installed on the HP Jetdirect print server:
G Jetdirect certificate. The Jetdirect certificate is used to
validate the identity of the Jetdirect device to clients and to
network authentication servers.
ENWW
While self-signed certificates are permitted and
allow data encryption, they do not ensure valid
authentication.
