print in RDLC ribbon shows Active X error

Hi,

I am using RDLC reports. In my machine, I have IE11. And the reports show quite well. But unfortunately, in my clients machine, when they click the print button on the Report viewer ribbon, they get an error "Printing is not available. Verify that ActiveX is enabled, or try using Internet explorer for Desktop". How can I overcome this error. How should I enable print option to my client. Please help me in this.

Thanks and regards,

Deepak
