About wireless communication

802.11 wireless technology allows you to wirelessly
connect to your HP Officejet/Officejet Pro device and a
computer without requiring a direct line of sight between
the devices.

Communication mode

There are two communication mode options:
Infrastructure: On an
infrastructure network,
computers and printers
communicate with each other
through an access point, such
as a Linksys wireless router or
Apple AirPort Base Station. The
computer sends information to
the HP device and other devices
on the network through this
router.
Once the HP device is successfully connected to the
network, all the computers on the network that have the
HP software installed can send information to the
HP device through the wireless router.
use of a wireless router. Ad hoc networks are typically
small and simple (for example, two wireless computers
or a wireless computer and a wireless printer).
Though ad hoc networks may be secured with a WEP
passphrase, they cannot be secured with a WAP key.
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".
Ad hoc: On an ad hoc
network, the computer
sends information directly
to the HP device without the

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
"Understand 802.11 wireless network settings" section
in the electronic User Guide available on your computer
after you install the software.
