More Information on Firewalls
If a firewall has been enabled on this PC, this may be preventing the
installer from detecting the printer. Temporarily disable the firewall on this
PC before continuing with the installation. If you have a firewall enabled (such as ZoneAlarm©,
BlackICE©, etc.), see your firewall vendor’s documentation
for instructions on how to disable the firewall.
Whenever the software firewall is disabled, HP strongly recommends that the
following things be installed on your computer:
- A hardware device that provides firewall protection between the Internet
and your computer, such as a gateway.
- An up-to-date virus detection program.
For general information on communication troubleshooting please refer to the
documentation that came with your printer and visit the support website at
http://www.hp.com/support.
Firewalls frequently cause
communication issues. If a firewall is enabled on a networked computer, the
following problems can occur:
During software installation:
- The HP printer installer will not be able to locate the HP
printer on the network. An error message will say that the setup was
unable to detect any printers on the network. To prevent this problem,
temporarily disable your firewall during the HP printer software
installation. Consult your firewall vendor’s documentation for instructions on
how to disable the firewall.
After software installation:
- If the IP address of the HP printer changes, then your computer will
not be able to communicate with the HP printer. All print, scan, PC
fax, and image transfer jobs will fail and the product status will indicate
that the HP printer is disconnected. In a home network environment,
it it normal for the IP address to sometimes change. If the software
firewall is not enabled, the new address is sent to the computer, which allows
the computer and the HP printer to continue communicating. To prevent
this issue, disable your firewall or if you are an advanced user familiar with
networking then you may choose to use a static IP address instead. For suggestions on how to configure your printer with a static IP
address, see hp’s website at
http://www.hp.com/support .
- If you have an HP all-in-one, you will not be able to use the memory card slots on the HP all-in-one to
transfer files to your computer. This is because files on the photo card
will not be accessible from the mapped network drive or the image transfer
software.
