I was looking at a way to change the IP address of a HP Web JetAdmin server and if it was possible to create ACLs based on Active Directory users when I come across a website presenting article to “hack” your network printer. It’s basically more of a compilation of useful things to know than hacking properly said but it could be quite useful and sometime fun. Anyway, it’s worth to check it out.

On the other site, if for any reason you need to change the IP address of your web JetAdmin server, here is how to do it:

You first need to backup your settings. You can find the backup tool here if WJA is installed on the default path:

c:\Program Files\Hewlett-Packard\HP Web Jetadmin 10\WJABackupRestore

note that if you have a non standard install path, you will have to edit the location of ’set OSQL’ inside the script.

Once the backup is finished, open the file ‘HP.Imaging.Wjp.Core.WebServer.config.xml‘ in the Settings\WjaService\config folder and replace the IP address with the new one.

you should find something like that:

<property name=”HostIPv4Address”>
<type>HP.Imaging.Wjp.Sdk.Core.Framework.ConfigurationItemString</type>
<value>your.IP.address</value>
</property>

Run the restore script and allow it to overwrite the existing database.

You should now have a fully working HP Web JetAdmin!
