window.print() is not printing the whole page

I have a page

I want to print this page. On print button i am using something like this

<input id="print" type="submit" onclick="window.print();" />

But the problem is it is not printing the whole page. Like it only print that is currently in the view. When i click on the print button then till Email:tahir@7-cs.com page print. It does not print the text below the scrollbar.

How can i print the whole text. Like suppose i have a very big page and i am using tabs to accommodate my page. And when click on print button, then i want to include the whole page including tabs. How can i do it?

Thanks
