print_iframe_with_jquery.js

(function($) {
  $(function() {

    $(".print").live('click', function(e) {
      e.preventDefault();

      // remove old printframe
      $("#printframe").remove();

      // create new printframe
      var iFrame = $('<iframe></iframe>');
      iFrame
      .attr("id", "printframe")
      .attr("name", "printframe")
      .attr("src", "about:blank")
      .css("width", "0")
      .css("height", "0")
      .css("position", "absolute")
      .css("left", "-9999px")
      .appendTo($("body:first"));

      // load printframe
      var url = $(this).attr("href");
      if (iFrame != null && url != null) {
        iFrame.attr('src', url);
        iFrame.load(function() {
          // nasty hack to be able to print the frame
          var tempFrame = $('#printframe')[0];
          var tempFrameWindow = tempFrame.contentWindow? tempFrame.contentWindow : tempFrame.contentDocument.defaultView;
          tempFrameWindow.focus();
          tempFrameWindow.print();
        });
      }
    });

  });
})(jQuery);

note have to change:
$("#printframe").remove();
by
if($("#printframe"))
$("#printframe").remove();
