HP Ew2400 - JetDirect Print Server Administrator's Manual page 11

Full-featured print servers support the following EAP/802.1X
method:
PEAP (Protected Extensible Authentication Protocol). PEAP is
a mutual authentication protocol that uses digital certificates
for network server authentication and passwords for client
authentication. For additional security, the authentication
exchanges are encapsulated within TLS (Transport Layer
Security). Dynamic encryption keys are used for secure
communications.
The network infrastructure device that connects the print server to
the network (such as an HP Procurve switch) must also support the
EAP/802.1X method used. In conjunction with the authentication
server, the infrastructure device can control the degree of network
access and services available to the print server client.
To configure the print server for EAP/802.1X authentication, you
must access the embedded Web server through your Web browser.

Wireless Print Server Authentication
HP Jetdirect ew2400 wired/wireless external print servers do not
support server-based authentication. They are intended for
small-office networks where authentication servers are not
typically used.
However, for security on wireless networks, some form of client
authentication is highly desired. The HP Jetdirect ew2400 supports
the following wireless authentication methods:
Shared Key. Authentication is based on a secret, common Wired
Equivalent Privacy (WEP) key that must be configured on each
wireless device. A device that does not have the proper WEP key
cannot access the network. Static WEP encyrption protocols are
used for network communications.
WPA-PSK. Authentication is based on Wi-Fi Protected Access
(WPA) standards through a Pre-Shared Key (PSK). When
selecting WPA-PSK authentication, a user-specified pass-phrase
must be entered to generate the pre-shared key. With WPA-PSK
authentication, dynamic WPA encryption protocols are used for
network communications to provide enhanced security.
