Assembly: System.Drawing (in System.Drawing.dll)
OnStartPrint creates the Graphics that is sent to the printer. After OnStartPrint is called, the OnStartPage method sets the Graphics to a graphic of a single page. (Use the OnStartPrint method to determine when and how to print a document. For example, you can delay printing for 30 minutes or adjust the printer settings for the document.) The OnEndPage method clears the Graphics, while the method deallocates the object.
