|
|
* $("#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
