/**
* Version 2.0
* -Contributors: "mindinquiring" : filter to exclude any stylesheet other than print.
* Tested ONLY in IE 8 and FF 3.5.3. No official support for other browsers, but will
* TRY to accomodate challenges in other browsers.
* Example:
* Print Button: <div id="print_button">Print</div>
* Print Area : <div class="PrintArea"> ... html ... </div>
* Javascript : <script>
* $("div#print_button").click(function(){
* $("div.PrintArea").printArea( [OPTIONS] );
* });
* </script>
* options are passed as json (json example: {mode: "popup", popClose: false})
*
* {OPTIONS} | [type] | (default), values | Explanation
* --------- | --------- | -------------------- | -----------
* @mode | [string] | ("iframe"), "popup" | printable window is either iframe or browser popup
* @popHt | [number] | (500) | popup window height
* @popWd | [number] | (400) | popup window width
* @popX | [number] | (500) | popup window screen X position
* @popY | [number] | (500) | popup window screen Y position
* @popTitle | [string] | ('') | popup window title element
* @popClose | [boolean] | (false), true | popup window close after printing
