4.If necessary, share the printer with other Macintosh computer users.
●Direct connection: Share the printer with the other Macintosh computer users. See 
To
share the printer on a locally shared network (Mac OS X (10.2, 10.3, 10.4)).
●Network connection: Individual Macintosh computer users who want to use the network
printer must install the printer software on their computers.
To share the printer on a locally shared network (Mac OS X (10.2,
10.3, 10.4))
When you connect the printer directly, you can share it with other computers using a simple form of
networking known as locally shared networking. Use this configuration only in small groups or when
usage is low. The computer that is connected to the printer is slowed down when many users print to
the printer.
Basic requirements for sharing in a Macintosh environment include the following items:
●The Macintosh computers must be communicating on the network using TCP/IP, and they must
have IP addresses. (AppleTalk is not supported.)
●The printer that is being shared must be connected to a built-in USB port on the host Macintosh
computer.
●The client Macintosh computers must be PowerMac or PowerPC computers.
●Both the host Macintosh computer and the client Macintosh computers that are using the shared
printer must have printer-sharing software installed, and the printer driver or PPD for the printer
that is installed. (You can run the installation program to install the printer sharing software and
associated Help files.)
For more information about USB printer sharing, see the support information on the Apple website
(
www.apple.com) or the Mac Help on the computer.

							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 on an ad hoc network (Mac OS) or To set up the printer for wireless
communication (Windows).
●Using SecureEasySetup (SES) 
See 
To set up wireless communication using SecureEasySetup (SES).
●Using Windows Connect Now  
See 
To set up wireless communication for multiple printers (Windows only).
NOTEIf you encounter problems, see Problems setting up or using wireless communication.
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 your networks network name (SSID) and communication mode (infrastructure or ad hoc)
from the configuration utility for the networks wireless access point (WAP) or the computers
network card.
●Find out the type of encryption your network uses, such as Wired Equivalent Privacy (WEP).
●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).
ENWW Setting up the printer for wireless communication (HP Officejet Pro K550dtwn) 85
 
						

							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
NOTEFor the available settings for the printer, see the network configuration page under
Understanding the configuration page.
For more information on wireless security, visit  
www.weca.net/opensection/pdf/whitepaper_wi-fi_security4-29-03.pdf.
●Network authentication: The printers factory default setting is Open, which does not require
security for authorization or encryption. The other possible values are OpenThenShared,
Shared, and WPA-PSK (Wi-Fi
® Protected Access Pre-Shared Key).
▲WPA increases the level of over-the-air data protection and access control on existing and
future Wi-Fi networks. It addresses all known weaknesses of WEP, the original native
security mechanism in the 802.11 standard.
▲WPA2 is the second generation of WPA security; providing enterprise and consumer Wi-Fi
users with a high level of assurance that only authorized users can access their wireless
networks.
●Data encryption:
●Wired Equivalent Privacy (WEP) provides security by encrypting data sent over radio waves
from one wireless device to another wireless device. Devices on a WEP-enabled network
use WEP keys to encode data. If your network uses WEP, you must know the WEP key(s) it
uses.
●WPA uses the Temporal Key Integrity Protocol (TKIP) for encryption and employs 802.1X
authentication with one of the standard Extensible Authentication Protocol (EAP) types
available today.
●WPA2 provides a new, encryption scheme, the Advanced Encryption Standard (AES). AES
is defined in counter cipher-block chaining mode (CCM) and supports the Independent Basic
Service Set (IBSS) to enable security between client workstations operating in ad hoc mode.

							Guidelines for reducing interference on a wireless network
The following tips will help reduce the chances for interference in a wireless network:
●Keep the wireless devices away from large metal objects, such as filing cabinets, and other
electromagnetic devices, such as microwaves and cordless telephones, as these objects can
disrupt radio signals.
●Keep the wireless devices away from large masonry structures and other building structures as
these objects can absorb radio waves and lower signal strength.
●For an infrastructure network, position the WAP in a central location in line of sight with the
wireless devices on the network.
●Keep all wireless devices on the network within range of one another.
Guidelines for ensuring wireless network security
To add hardware addresses to a wireless access point (WAP)
MAC filtering is a security feature in which a wireless access point (WAP) is configured with a list of
MAC addresses (also called hardware addresses) of devices that are allowed to gain access to the
network through the WAP.
If the WAP does not have the hardware address of a device attempting to access the network, the
WAP denies the device access to the network.
If the WAP filters MAC addresses, then the printers MAC address must be added to the WAPs list of
accepted MAC addresses.
1.Print the network configuration page. See 
Understanding the configuration page.
2.Open the WAPs configuration utility, and add the printers hardware address to the list of
accepted MAC addresses.
Other guidelines
To keep the wireless network secure, follow these guidelines:
●Use a password with at least 20 random characters. You can use up to 63 characters in a WPA
password.
●Avoid any common words or phrases, easy sequences of characters (such as all 1s), and
personally-identifiable information for passwords. Always use random strings composed of
uppercase and lowercase letters, numbers, and if allowed, special characters such as
punctuation.
●Change the password periodically.
●Change the default password provided by the manufacturer for administrator access to the
access point or wireless router. Some routers let you change the administrator name as well.
●Place the access point or router in the center of a room and not near a window.
●Turn off administrative access over wireless if possible. If you do this, you need to connect to the
router with a wired Ethernet connection when you want to make configuration changes.
90 Chapter 6   Configuring and managing the printer ENWW
 
						

							●Turn off remote administrative access over the Internet on your router, if possible. You can use
Remote Desktop to make an encrypted connection to a computer running behind your router and
make configuration changes from the local computer you are accessing over the Internet.
●To avoid accidentally connecting to another partys wireless network, turn off the setting to
automatically connect to non-preferred networks. This is disabled by default in Windows XP.
