I just set up a home network and printer sharing using XP setup tools. I am having trouble printing on a Canon printer attached to a desktop computer, from my laptop. I am able to see the printer when choosing File/Print. But when I try to print, I receive an error. I tried to add the desktop computer's IP address as a trusted zone. I did this by going to the desktop computer's command line and typing IPCONFIG. I added this IP address to the Zone Alarm firewall on the Laptop computer. I still received an error when attempting to print. When I closed Zone Alarm, the page printed fine. The deskop computer uses the Microsoft firewall. Anyone have any ideas on what I should do to be able to print? Thanks.

Operating System:Windows XP Pro
Product Name:ZoneAlarm (Free)
Software Version:6.5
