A software firewall can prevent the computer from finding the printer on the
network during the printer software installation process. If the computer cannot
discover the printer, the printer software cannot be installed on the computer.
If the computer has a software firewall other than the firewall included with
Windows XP installed (such as, BlackICE®, ZoneAlarm®, or Brickhouse®), see
the documentation that came with the firewall for help in disabling the firewall.
Note The software firewall included with Windows XP does not interfere
with the connection to the printer. If the computer is only running the
Windows XP software firewall, you do not need to disable the firewall
during software installation or assign the printer a static IP address.
Before installing the printer software on a computer, temporarily disable the
software firewall on the computer, and then assign the printer a static IP address.
After the printer software is installed on the computer, re-enable the firewall.
For instructions about connecting the printer to a network on which computers are
protected by a software firewall, go to Configure the printer for a software
firewall on page 8.
● Place the printer and the computer on the same subnet
A subnet is a small network that is part of a larger network. If the computer is on a
different subnet than the printer, the software installation can be problematic.
Compare the printer IP address listed on the HP Report page with the IP address
for the computer. If the first set of digits in the IP addresses are not identical, then
the printer and the computer are not on the same subnet. For example, if the
computer IP address begins with 169 and the printer IP address begins with 10,
then the printer and the computer are not on the same subnet.
To find the IP address on a Windows computer:
1. Click Start, click Run, and then enter Command.
2. Type ipconfig at the command prompt, and then press Enter.
To find the IP address on a Mac OS X computer:
1. Open the Network control panel.
2. Select Airport in the Show drop-down list, and then click TCP/IP.
If the computer and the printer are not on the same subnet, move the printer to the
same subnet as the computer, and then run the setup wizard again.
1 The computer and the printer are on different subnets.
