I use OS : Window7 Ultimate 64 bit, Zone Alarm Extreme Suite version 9.1.008.000, a printer Canon MX320.
When I try print a page from IE8 64 bit, the IE8 crash, I don't have the problem in IE8 32 bit, Safari, Mozilla Firefox & Google Chrome.
When I disable Zone Alarm Extreme Suite - I have no problem in IE8 64 bit.
