Since you're doing this in PHP, then just have a link like this:
<a href="{$php_self}?mode=printable">Printable version</a>
and then in your script have sections like this so your banner/links aren't shown on the print version:
if ($_GET['mode'] != 'printable') {
echo "<img src='banner.jpg'>";
}
.
.
. // Common elements that are shown whether printing or not.
.
.
if ($_GET['mode'] != 'printable') {
echo "HTML links follow...";
}
