Configure your firewall to work with HP devices

A personal firewall, which is security software running
on your computer, can block network communication
between your HP device and your computer.
If you are having problems such as:
• Printer not found when installing HP software
• Unable to print, print job stuck in queue or printer
goes offline
• Scan communication errors or scanner busy
messages
• Unable to see printer status on your computer
The firewall might be preventing your HP device from
notifying computers on your network where it can be
found. If the HP software cannot find the HP device
during installation (and you know the HP device is on
the network), or you have already successfully installed
HP software and experience problems, try the following:
1. If you are using a computer running Windows, in the
firewall configuration utility, look for an option to
trust computers on the local subnet (sometimes called
the "scope" or "zone"). By trusting all computers on
the local subnet, computers and devices in your
home or office can communicate with each other
while still being protected from the internet. This is
the easiest approach to use.
2. If you do not have the option to trust computers on
the local subnet, add incoming UDP port 427 to
your firewall's list of allowed ports.

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
• TCP port: 139

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 set
as a trusted software 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.
