InvalidPrinterException

Remarks

OnStartPrint is called immediately after PrintDocument raises the BeginPrint event.

OnStartPrint creates the Graphics that is displayed during the print preview. After OnStartPrint is called, the OnStartPage method sets the Graphics to a graphic of a single page. The OnEndPage method clears the Graphics, while the OnEndPrint method deallocates the object.

OnStartPrint verifies that the printer settings are valid.
