NOTE: Not all firewalls require you to differentiate between incoming and
outgoing ports, but some do.
Another common problem is that HP software is not trusted by your firewall to access
the network. This can happen if you answered “block“ to any firewall dialog boxes that
appeared when you installed the HP software.
If this occurs, and if you are using a computer running Windows, check that the
following programs are in your firewall’s list of trusted applications; add any that are
missing.
• hpqkygrp.exe, located in C:\program files\HP\digital imaging\bin
• hpqscnvw.exe, located in C:\program files\HP\digital imaging\bin
• hpqste08.exe, located in C:\program files\HP\digital imaging\bin
• hpqtra08.exe, located in C:\program files\HP\digital imaging\bin
• hpqthb08.exe, located in C:\program files\HP\digital imaging\bin
NOTE: Refer to your firewall documentation on how to configure the firewall port
settings and how to add HP files to the “trusted“ list.
NOTE: Some firewalls continue to cause interference even after you disable
them. If you continue to have problems after configuring the firewall as described
above and if you are using a computer running Windows, you might need to
uninstall the firewall software in order to use the HP device over the network.
