Deskjet F4140 device setup failure

[Assasin boy]

I just bought a printer multifunction HP Deskjet F4140. I have already installed on 2 machines without worry. I need to install it on another laptop , and there is failure . Yet, nothing different from 2 other PCs : Windows XP SP2 even on Dell PCs. I think this is the configuration of XP to block the process. during the installation procedure , a first window " Hardware Wizard " opens, it settles. Shortly afterward a new window " Hardware Wizard " opens , and the recognition of the driver is in check ( support for USB printing ). Error Message unsigned driver or driver signing is not recognized by XP. I called HP which made me uninstall everything in depth , turned off all firewalls and antivirus software, then reinstalled completely. same result. Please help? Thank you for your advice.
