Method 2 (Windows Only); Configure Your Firewall To Work With Hp Devices - HP OfficeJet Pro 8500 Guía De Inicio

Method 2 (Windows only)

1. Make sure your computer has an ad hoc network
profile. For more information, see the documentation
available with your operating system.

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.
NOTE: Not all firewalls require you to differentiate
between incoming and outgoing ports, but some do.
2. Follow the instructions in "Connect the HP Officejet/
Officejet Pro device to your wireless network" on
page 5 and select the network that corresponds to
the ad hoc network profile for your computer.
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.
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.
