Unable to print CRXI reports from viewer

We have CR XI installed on our web server and use Cold Fusion to call up crystal reports. As people have started switching over to IE8, we seem to have problems where they are unable to print. The get the Crystal Reports Viewer - Webpage Dialog box to box up, just a white box. But no print dialog ever populates. They can export to PDF and then print the report, but not using the print dialog.

Any suggestions? Thoughts?

Thanks so much!!
