PHP代码打印模型窗口打印滚动条也是如此

I am using PHP Bootstrap, and trying to print Model window, My problem is that it is printing with scrollbar and skipping hidden content behind the scrollbar, i need to print entire content irrespective of the scrollbar appearing or not. It is ok if I get multiple pages to print.

Please refer these screenshots,

This is my model window content with scrollbar hiding some content

What i get in print preview is this

I just want entire content to be printed may be on multiple pages but without scrollbar,

Removing scroll bar option from Model window makes it very long in some cases, so that is not the option.
