Norton 2010 print request shows as intrusion prevention

I have Norton 2010 installed on a Dell desktop and Dell laptop connected through a wireless home network.  Both are running windows Vista home basic.  They share a printer connected to the desktop through a USB connection.

 

I have been able to print from the laptop until recently.  I had to reinstall Norton 2010 on the desktop.  After reinstalling Norton 2010 I have not been able to print from the laptop.  When I look at the Norton history on the laptop, it shows an intrusion prevention from the IP address of the desktop.

 

Any ideas?

 

Thanks,

Kathryn
