PrintDocument.PrintDocument Constructor

Initializes a new instance of the PrintDocument class.

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

public PrintDocument ()
public PrintDocument ()
public function PrintDocument ()
Not applicable.

The default constructor initializes all fields based upon the default printer. Typically, after creating a new PrintDocument, you set printer and page settings that affect the output through the PrinterSettings and DefaultPageSettings properties, respectively.

The following code example sets a document's page orientation to landscape, and prints the document.

Use the System.Drawing, System.Drawing.Printing, and System.IO namespaces for this example.
