How to Print Crystal Report without any dialog message on the client side

Hi!

I've read too much questions like this, but i can't find any answer.

How can i print a report on the client side directly?

I have three buttons, "Generate Report", "Generate PDF", "Print".

I want when the "Print" button was clicked, automaticaly the report is printed using default printer, like PrintToPrinter function, but in the client side.

Thanks!
