Network Name (Ssid); Security - HP 8500 - Officejet Pro All-in-One Color Inkjet Getting Started Manual

Also, the performance of the network might not be as
good as an infrastructure network.
The HP device is pre-configured by the factory to
connect to an ad-hoc network with the SSID "hpsetup".
NOTE: If you reset the network settings from the control
panel at any point, the SSID will be reset to "hpsetup".

Network name (SSID)

The network name provides a basic connection to a
wireless network. All devices trying to communicate with
each other must have the same SSID and security
settings.
CAUTION: To prevent other users from accessing your
wireless network, HP strongly recommends using a
password or passphrase (WPA or WEP security) and a
unique network name (Service set identifier (SSID)) for
your wireless router. Your wireless router might have
been shipped with a default network name, which is
typically the manufacturer name. If you use the default
network name, your network can be easily accessed by
other users using the same default network name (SSID).
It also means that the HP device might accidentally
connect to a different wireless network in your area
which uses the same network name. If this happens you
will not be able to access the HP device. For more
information on how to change the network name, see
the documentation that came with your wireless router.

Security

The HP Officejet/Officejet Pro supports WEP, WPA,
and WPA2 security methods. For more information,
see the electronic User Guide available on your
computer after you install the software.
