ENWW Introducing the HP Jetdirect Print Server 13
Without an Authentication Server
For small office networks that do not have an authentication server, 
HP Jetdirect wireless print servers support network authentication 
using Extensible Authentication Protocol with a Pre-shared key 
(EAP/PSK). Using a pass-phrase entered by the user, the print 
server generates a pre-shared key used for network access and 
communications. 
When configured for EAP/PSK authentication, the print server uses 
Wi-Fi Protected Access (WPA) dynamic encryption protocols for 
wireless communications.
Encryption
HP Jetdirect 802.11b wireless print servers support static WEP 
(Wired Equivalent Privacy) encryption. For static WEP encryption, 
a network WEP key of fixed length (40/64-bit or 104/128-bit) is 
shared by each device on the network. 
Depending on your wireless print server model, the following 
dynamic encryption protocols are supported: 
● dynamic WEP
● Wi-Fi Protected Access (WPA)
Note If not supported by your HP Jetdirect wireless print 
server, EAP/PSK authentication and Robust 
encryption will not be displayed as a selectable 
configuration option.
When dynamic encryption is used, encryption keys are periodically 
changed automatically and provide enhanced security because they 
will likely change before someone can decipher them. 
In dynamic WEP encryption, each device on the wireless network 
is assigned a different encryption key that expires at preset 
intervals and is then replaced. 
WPA encryption is an enhanced version of dynamic WEP and offers 
improved security. For example, new encryption keys are generated 
for fixed amounts of data (10 kilobytes) transmitted by a device on 
the network.
