  NameDescription
Protected propertyCanRaiseEventsGets a value indicating whether the component can raise an event. (Inherited from Component.)
Public propertyContainerGets the IContainer that contains the Component. (Inherited from Component.)
Public propertyDefaultPageSettingsGets or sets page settings that are used as defaults for all pages to be printed.
Protected propertyDesignModeGets a value that indicates whether the Component is currently in design mode. (Inherited from Component.)
Public propertyDocumentNameGets or sets the document name to display (for example, in a print status dialog box or printer queue) while printing the document.
Protected propertyEventsGets the list of event handlers that are attached to this Component. (Inherited from Component.)
Public propertyOriginAtMarginsGets or sets a value indicating whether the position of a graphics object associated with a page is located just inside the user-specified margins or at the top-left corner of the printable area of the page.
Public propertyPrintControllerGets or sets the print controller that guides the printing process.
Public propertyPrinterSettingsGets or sets the printer that prints the document.
Public propertySiteGets or sets the ISite of the Component. (Inherited from Component.)

  NameDescription
Public methodCreateObjRefCreates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
Public methodDispose()Releases all resources used by the Component. (Inherited from Component.)
Protected methodDispose(Boolean)Releases the unmanaged resources used by the Component and optionally releases the managed resources. (Inherited from Component.)
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeReleases unmanaged resources and performs other cleanup operations before the Component is reclaimed by garbage collection. (Inherited from Component.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetLifetimeServiceRetrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Protected methodGetServiceReturns an object that represents a service provided by the Component or by its Container. (Inherited from Component.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodInitializeLifetimeServiceObtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Protected methodMemberwiseClone()Creates a shallow copy of the current Object. (Inherited from Object.)
Protected methodMemberwiseClone(Boolean)Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
Protected methodOnBeginPrintRaises the BeginPrint event. It is called after the Print method is called and before the first page of the document prints.
Protected methodOnEndPrintRaises the EndPrint event. It is called when the last page of the document has printed.
Protected methodOnPrintPageRaises the PrintPage event. It is called before a page prints.
Protected methodOnQueryPageSettingsRaises the QueryPageSettings event. It is called immediately before each PrintPage event.
Public methodPrintStarts the document's printing process.
Public methodToStringInfrastructure. Provides information about the print document, in string form. (Overrides Component.ToString().)

  NameDescription
Public eventBeginPrintOccurs when the Print method is called and before the first page of the document prints.
Public eventDisposedOccurs when the component is disposed by a call to the Dispose method. (Inherited from Component.)
Public eventEndPrintOccurs when the last page of the document has printed.
Public eventPrintPageOccurs when the output to print for the current page is needed.
Public eventQueryPageSettingsOccurs immediately before each PrintPage event.

Typically, you create an instance of the PrintDocument class, set properties such as the DocumentNameand PrinterSettings, and call the Print method to start the printing process. Handle the PrintPage event where you specify the output to print, by using the GraphicsGraphics property of the PrintPageEventArgs.

For more information about printing from a Windows Form application, see the Windows Forms Print Support. If you wish to print from a Windows Presentation Foundation application, see the System.Printing namespace.

The following code example prints the file named C:\My Documents\MyFile.txt on the default printer. To run the example, create a new Windows Forms project and paste the example code into the form, replacing the file contents. For C#, you will need to delete the Form1.Designer.cs file. Also, change the path to the file you want to print.

NoteNote

The example requires that each line fits within the page width.

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