*      importCSS: true,           * import page CSS
*      printContainer: true,      * grab outer container as well as the contents of the selector
*      loadCSS: "path/to/my.css", * path to additional css file
*      pageTitle: "",             * add title to print page
*      removeInline: false,       * remove all inline styles from print elements
*      printDelay: 333,           * variable print delay S. Vance
*      header: null               * prefix to html
*  });
*
* Notes:
*  - the loadCSS will load additional css (with or without @media print) into the iframe, adjusting layout
