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

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

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.

Though ad hoc networks may be secured with a WEP
