Add hardware addresses to a wireless router12
Advanced firewall information
The following ports are also used by your HP device and might need to be opened on your firewall configuration.
Incoming ports (UDP) are destination ports on the computer while outgoing ports (TCP) are destination ports on the
HP device.
• Incoming (UDP) ports: 137, 138, 161, 427
• Outgoing (TCP) ports: 137, 139, 427, 9100,
9220, 9500
The ports are used for the following functions:
Printing
• UDP ports: 427, 137, 161
• TCP port: 9100
Photo card upload
• UDP ports: 137, 138, 427
• TCP port: 139
Scanning
• UDP port: 427
• TCP ports: 9220, 9500
HP device status
UDP port: 161
Faxing
• UDP port: 427
• TCP port: 9220
HP device installation
UDP port: 427
Add hardware addresses to a wireless router
MAC filtering is a security feature in which a wireless
router is configured with a list of MAC addresses
(also called “hardware addresses“) of devices that are
allowed to gain access to the network.
If the router does not have the hardware address of a
device attempting to access the network, the router
denies the device access to the network:
1. Locate the MAC address for the HP Officejet/
Officejet Pro device. This address is printed on the
serial number label (typically located on the back
of the HP device), and this address is also printed
on the Network Configuration Page. For more
information about printing the Network
Configuration Page, see “Make sure the HP
Officejet/Officejet Pro device is on the network”
on page 8.
2. Open the router’s configuration utility, and add the
device’s wireless hardware address to the list of
accepted MAC addresses.
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.
Ad hoc: On an ad hoc
network, the computer
sends information directly
to the HP device without the
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.
