PrintController::OnStartPrint Method (PrintDocument^, PrintEventArgs^)

 

When overridden in a derived class, begins the control sequence that determines when and how to print a document.

Namespace:   System.Drawing.Printing
Assembly:  System.Drawing (in System.Drawing.dll)

public:
virtual void OnStartPrint(
	PrintDocument^ document,
	PrintEventArgs^ e
)

Parameters

document
Type: System.Drawing.Printing::PrintDocument^

A PrintDocument that represents the document currently being printed.

e
Type: System.Drawing.Printing::PrintEventArgs^

A PrintEventArgs that contains the event data.

OnStartPrint is called immediately after the PrintDocument raises the BeginPrint event.

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. OnStartPrint creates the Graphics that is sent to the printer. After OnStartPrint is called, the OnStartPage method sets the Graphics to one of a single page. The OnEndPage method clears the Graphics, while the OnEndPrint method deallocates the object.

The OnStartPrint method is a good place to verify that PrinterSettings are valid.
