如何在没有浏览器生成的页码，URL等的情况下打印PHP页面？

Question

I have a PHP page that I need to print. I managed to remove unwanted elements from printing with a print stylesheet (print.css) below. However it does not remove browser generated header, page numbers, URL and date. I am using bootstrap framework. bootstrap.min.css does not have any '@media print' sort of thing. Need some better CSS ideas to achieve this. Thank you.

    /* Remove unwanted elements */
    /* Assign class="noprint" in the HTML. Header and navigation (<div id="header"> and <div id="nav">) */

    #header, #nav, .noprint
    {
    display: none;
    }

   /* Ensure the content spans the full width */
   #container, #container2, #content
    {
    width: 100%; margin: 0; float: none;
    }

    /* Change text colour to black (useful for light text on a dark background) */
    .lighttext
    {
    color: #000 
    }

    /* Remove links */
    a:link, a:visited, .navbar-link
    {
    display: none;
    }

As far as I am aware you can not change this via css however when you bring up your browsers print dialog it should present you with an option to exclude headers and footers (i.e. page number and url).
