Emit the javascript code to print the page in the click event handler. Like
this:
protected void Button_Click(object sender, System.EventArgs e) {
    Page.RegisterStartupScript("PrintPage","<script
language=\"JavaScript\">window.print();</script>");
}

Use the page-break-before or page-break-after CSS styles to control page
breaks when printing.

<HR style="page-break-before: always;">
<!--- HTML to be on the page -->

You cannot use the window.print() method to print the contents of a
collection. Therefore you'll have to render each element as HTML. Use HTML
code similar to the example above to force page breaks.
