Example

Description

PrintDocument class will use the Print method to print the document. Print method needs two parameters, DocumentPaginator object and the document name. DocumentPaginator is an abstract base class that supports creation of multiple-page elements from a single document. By default, each FixedDocument has DocumentPaginator property that contain DocumentPaginator object for the fixed document.

Additionally, you can specify a custom paginator class to add custom elements for printing purpose only, such as header or footer.

The following code shows how to add header and footer element in a FixedDocument for printing purpose.
