General network troubleshooting
If you are unable to install the HP software provided with the printer, verify that:
All cable connections to the computer and the printer are secure.
The network is operational and the network hub, switch, or router is turned on.
All applications, including virus protection programs, spyware protection
programs, and firewalls, are closed or disabled for computers running Windows.
The printer is installed on the same subnet as the computers that use the printer.
If the installation program cannot discover the printer, print the network configuration
page, and enter the IP address manually in the installation program. For more
information, see Understand the network configuration page.
