Force an element to take exactly half of available height in print media

I am dynamically creating elements (student bills) on a web page which I want to print. I want this element to take only half of the total printable height in print media, so that I can print two elements on one page.

But in the picture, It's clear that some part of the third element is appearing on first page, which should actually go on the second page.

How can I force this element (one student's bill) to take exactly half of the height of the page?

<div class="col-md-6">
    <div id="page-wrap">



        <div style="clear:both"></div>

        <div id="customer">

Try this

add a div after every 2nd elements with page-break-after property

<div style="page-break-after:always"></div>

page-break-after property sets whether a page break should occur AFTER a specified element
