Make sure the following files are included in the exceptions list of the firewall: • C:\Program Files\Hp\Digital maging\bin\hpqtra08.exe. • C:\Program Files\Hp\Digital Imaging\bin\hpqscnvw.exe or hpiscnapp.exe. • C:\Program Files\Hp\Digital Imaging\bin\hpqdstcp.exe.

Other network problems after software installation If the HP Photosmart has been successfully installed, and you are experiencing problems such as not being able to print, try the following: • Turn off the router, product, and computer, and then turn them back on in this order: router first, then the product, and finally the computer. Sometimes, cycling the power will recover a network communication issue. • If the previous step does not solve the problem and you have successfully installed the HP Photosmart Software on your computer, run the Network Diagnostic tool. To run the Network Diagnostic tool > In the Solution Center, click Settings, click Other Settings, and then click Network Toolbox. On the Utilities tab, click Run Network Diagnostics.
