PrintDocument Constructor

Initializes a new instance of the PrintDocument class.

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

public PrintDocument()

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.

using System;
using System.IO;
using System.Drawing;
using System.Drawing.Printing;
using System.Windows.Forms;

    public PrintingExample() : base() 
    {
       // The Windows Forms Designer requires the following call.
       InitializeComponent();
