Setting up the printer for wireless communication
(HP Officejet Pro K550dtwn)
You may set up the printer for wireless communication using one of the following ways:
• Using a cross cable or network cable
See "To set up the printer for wireless communication" on page 23.
• Using SecureEasySetup (SES)
See "To set up wireless communication using SecureEasySetup (SES)" on page 23.
• Using Windows Connect Now
See "To set up wireless communication for multiple printers (Windows only)" on page 24.
Note:
• If you encounter problems, see "Troubleshooting
problems for wireless communication" on page 24.
• To use the printer with any wireless connection,
you must run the installation program at least once
from the Starter CD and create a wireless
connection.
• Make sure the printer is not connected to the
network using a network cable.
• The sending device must have built-in 802.11
capabilities or an 802.11 wireless card installed.
• It is recommended that the printer and the computers
that use the printer be on the same subnet.
Before installing the printer software, you may wish to
find out the settings of your network. Obtain the
information from your system administrators, or complete
the following tasks:
• Obtain the network name (SSID) and communication
mode (infrastructure or ad hoc) from the
configuration utility for the network's wireless access
point (WAP) or the computer's network card.
• Find out the type of encryption your network uses,
such as Wired Equivalent Privacy (WEP) or Wi-Fi
Protected Access (WPA).
• Find out the security password or encryption key of
the wireless device.

Understanding 802.11 wireless
network settings
Network name (SSID)
By default, the printer looks for the wireless network
name or Service Set Identifier (SSID) named "hpsetup".
Your network may have a different SSID.
Communication mode
There are two communication mode options:
Ad hoc: On an ad hoc network, the printer is set to ad
hoc communication mode, and communicates directly
with other wireless devices without the use of a wireless
access point (WAP):
All devices on the ad hoc network must:
• Be 802.11 compatible
• Have ad hoc as the communication mode
• Have the same network name (SSID)
• Be on the same subnet and same channel
®
• Have the same 802.11 security settings
Infrastructure (recommended): On an infrastructure
network, the printer is set to infrastructure communication
mode, and communicates with other devices on the
network, whether the devices are wired or wireless,
through a WAP. WAPs commonly act as routers or
gateways on small networks.
Security Settings
For the available settings for the printer, see the network
configuration page under "Understanding the
configuration page" in the onscreen user guide.
