PrintDocument.PrintDocument Constructor

Initializes a new instance of the PrintDocument class.

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

Public Sub New
Dim instance As New 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.
