|
||
|
|
* pageTitle: "", // add title to print page
|
||
|
|
* removeInline: false, // remove all inline styles from print elements
|
||

|
||
|
|
* header: null, // prefix to html
|
||
|
|
* footer: null, // postfix to html
|
||
|
|
* base: false, // preserve the BASE tag, or accept a string for the URL
|
||
|
|
* formValues: true, // preserve input/form values
|
||
|
|
* canvas: false, // copy canvas elements
|
||
|

||
|
|
* });
|
||
|
|
*
|
||
|
|
* Notes:
|
||
|
|
* - the loadCSS will load additional CSS (with or without @media print) into the iframe, adjusting layout
