how to make printable version of a webpage?

You can make printer friendly version of your page with @media print

@media print {
        your styles here
}

For example in Foundation they have the basic rules to which you can add anything of your own:

@media print {
    * { background: transparent !important; color: black !important; text-shadow: none !important; filter:none !important;
    -ms-filter: none !important; } /* Black prints faster: sanbeiji.com/archives/953 */
    p a, p a:visited { color: #444 !important; text-decoration: underline; }
    p a[href]:after { content: " (" attr(href) ")"; }
    abbr[title]:after { content: " (" attr(title) ")"; }
    .ir a:after, a[href^="javascript:"]:after, a[href^="#"]:after { content: ""; }  /* Don't show links for images, or javascript/internal links */
    pre, blockquote { border: 1px solid #999; page-break-inside: avoid; }
    thead { display: table-header-group; } /* css-discuss.incutio.com/wiki/Printing_Tables */
    tr, img { page-break-inside: avoid; }
    @page { margin: 0.5cm; }
    p, h2, h3 { orphans: 3; widows: 3; }
    h2, h3{ page-break-after: avoid; }
    .hide-on-print { display: none !important; }
    .print-only { display: block !important; }
}

Use CSS with @media rules. Define your styles for displaying on the screen with @media screen and @media print for print-view. Control page breaks with page-break-* attributes.

@media screen {
    body {
        background-image: url(/images/background.png);
    }
}
@media print {
    body {
        background-image: none;
    }
    tr {
        page-break-inside: avoid;
    }
}
