* Usage:
*
* $("#mySelector").printThis({
* debug: false, * show the iframe for debugging
* 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
* header: null * prefix to html
* });
*
* Notes:
* - the loadCSS will load additional css (with or without @media print) into the iframe, adjusting layout
