You can use the HP PSC’s internal Web page to:
• Check printer (HP PSC) status
• View network statistics
• Adjust the network configuration
• Scan pages over the network
• Link to HP's website for support and to purchase supplies
Caution! Use caution when changing the print server's wireless
network settings; you might lose your connection. If you lose your
connection, you might need to use the new settings to reconnect.
If the print server loses its network connection, you might need to
reset it to factory-default and reinstall the software.
Note: Do not disable TCP/IP (Transmission Control Protocol/Internet
Protocol) on your computer. It is required for communication with the
embedded Web server.
adding security to the network
As with other networks, security for wireless LANs (WLANs) focuses on access
control and privacy. Traditional WLAN security includes the use of Service Set
Identifiers (SSIDs), open or shared-key authentication, static WEP keys, and
optional Media Access Control (MAC) authentication. This combination offers a
rudimentary level of access control and privacy.
Advanced forms of authentication and encryption might also be employed on the
WLAN. These include WPA/802.1x, which incorporates Temporal Key Integrity
Protocol (TKIP) security and EAP/802.1x authentication, and WPA/PSK. All of
the afore-mentioned terms are discussed in wireless network settings on
page 79, and in the Reference Guide for your HP PSC.
Note: To protect your wireless network, HP strongly suggests you implement
a wireless security scheme (either WEP or WPA) during setup, use an
antivirus program to protect against computer viruses, and follow basic
security rules such as setting strong passwords and not opening unknown
attachments. Other network components, including firewalls, intrusion-
detection systems, and segmented networks, should also be considered as
part of your network design.
to add security to your network after the device is installed
Note: If you decide to add encryption and authentication to your network
after installing the HP PSC, change the settings on your HP PSC prior to
changing them on other nodes on your network.
