PrintDocument.PrintPage イベント
アセンブリ: System.Drawing (system.drawing.dll 内)

Dim instance As PrintDocument Dim handler As PrintPageEventHandler AddHandler instance.PrintPage, handler
public: event PrintPageEventHandler^ PrintPage { void add (PrintPageEventHandler^ value); void remove (PrintPageEventHandler^ value); }

印刷する出力ファイルを指定するには、PrintPageEventArgs に含まれている Graphics を使用します。たとえば、印刷するテキストの行を指定するには、System.Drawing.Graphics.DrawString メソッドを使用してテキストを描画します。
出力を指定する他に、PrintPageEventArgs.HasMorePages プロパティを true に設定することによって、印刷する追加ページがあるかどうかを指定できます。既定値は false です。印刷するページが終了したことを示します。また、PageSettings を使用して、個別のページ設定を変更できます。PrintPageEventArgs.Cancel プロパティを true に設定することによって、印刷ジョブを取り消すこともできます。ページごとに異なるページ設定を使用してドキュメントを印刷するには、QueryPageSettings イベントを処理します。
イベントをイベント ハンドラに関連付けるには、PrintPageEventHandler デリゲートのインスタンスをイベントに追加します。イベント ハンドラは、該当するイベントが発生すると必ず呼び出されます。デリゲートを使用したイベント処理の詳細については、「イベントとデリゲート」を参照してください。

PrintPage イベントを処理するコード例を次に示します。
この例では、System.Drawing、System.Drawing.Printing、および System.IO の各名前空間を使用します。
