PrintDocument.Print メソッド

定義

ドキュメントの印刷プロセスを開始します。Starts the document's printing process.

public:
 void Print();
public void Print ();
member this.Print : unit -> unit
Public Sub Print ()

例外

PrinterName プロパティで指定されたプリンターが存在しません。The printer named in the PrinterName property does not exist.

次のコード例では、コマンドラインで指定されたファイルを既定のプリンターに出力します。The following code example prints the file that is specified through the command line to the default printer.

注意

この例では、各行がページ幅内に収まる必要があります。The example requires that each line fits within the page width.

この例では、System.ComponentModelSystem.DrawingSystem.Drawing.PrintingSystem.IO、および System.Windows.Forms の名前空間を使用します。Use the System.ComponentModel, System.Drawing, System.Drawing.Printing, System.IO, and System.Windows.Forms namespaces for this example.

注釈

PrintPage イベントを処理し、PrintPageEventArgsに含まれる Graphics を使用して、印刷する出力を指定します。Specify the output to print by handling the PrintPage event and by using the Graphics included in the PrintPageEventArgs.

ドキュメントを印刷するプリンターを指定するには、PrinterSettings.PrinterName プロパティを使用します。Use the PrinterSettings.PrinterName property to specify which printer should print the document.

Print メソッドは、印刷ダイアログを使用せずにドキュメントを印刷します。The Print method prints the document without using a print dialog. ユーザーに印刷設定を選択する機能を提供する場合は、PrintDialog を使用します。Use a PrintDialog when you want to offer the user the ability to choose print settings.

注意

Print メソッドによって処理されない例外が、印刷中にスローされた場合、ドキュメントの印刷は中止されます。If an exception that is not handled by the Print method is thrown during printing, the printing of the document is aborted.
