Hi,
Please open your Internet Explorer, click Tools - Internet Options - Advanced Tab,
Under Settings, do not check "Enable third-party browser extensions*", then Apply and OK. Restart the IE, check if it can print.
If it resolve the issue, please fully scan your computer to find if there's any virus or malware.
Furthermore, you can remove IE9, and use IE8 to check the result.
Hope that helps.
Regards,
Leo Huang
