PrintDocument.PrintPage 이벤트

정의

현재 페이지에 대해 인쇄할 출력이 필요할 때 발생합니다.Occurs when the output to print for the current page is needed.

public:
 event System::Drawing::Printing::PrintPageEventHandler ^ PrintPage;
public event System.Drawing.Printing.PrintPageEventHandler PrintPage;
member this.PrintPage : System.Drawing.Printing.PrintPageEventHandler 
Public Custom Event PrintPage As PrintPageEventHandler

설명

출력할 출력을 지정 하려면 PrintPageEventArgsGraphics 속성을 사용 합니다.To specify the output to print, use the Graphics property of the PrintPageEventArgs. 예를 들어 인쇄할 텍스트 줄을 지정 하려면 Graphics.DrawString 메서드를 사용 하 여 텍스트를 그립니다.For example, to specify a line of text that should be printed, draw the text using the Graphics.DrawString method.

출력을 지정 하는 것 외에도 PrintPageEventArgs.HasMorePages 속성을 true설정 하 여 인쇄할 추가 페이지가 있는지 여부를 나타낼 수 있습니다.In addition to specifying the output, you can indicate if there are additional pages to print by setting the PrintPageEventArgs.HasMorePages property to true. 기본값은 false이며 인쇄할 페이지가 더 이상 없음을 나타냅니다.The default is false, which indicates that there are no more pages to print. 또한 PageSettings를 통해 개별 페이지 설정을 수정할 수 있으며 PrintPageEventArgs.Cancel 속성을 true로 설정 하 여 인쇄 작업을 취소할 수 있습니다.Individual page settings can also be modified through the PageSettings and the print job can be canceled by setting the PrintPageEventArgs.Cancel property to true. 다른 페이지 설정을 사용 하 여 문서의 각 페이지를 인쇄 하려면 QueryPageSettings 이벤트를 처리 합니다.To print each page of a document using different page settings, handle the QueryPageSettings event.

이벤트를 이벤트 처리기와 연결 하려면 PrintPageEventHandler 대리자의 인스턴스를 이벤트에 추가 합니다.To associate the event with your event handler, add an instance of the PrintPageEventHandler delegate to the event. 이벤트 처리기는 이벤트가 발생할 때마다 호출 됩니다.The event handler is called whenever the event occurs. 대리자를 사용 하 여 이벤트를 처리 하는 방법에 대 한 자세한 내용은 참조 하세요. 이벤트 처리 및 발생합니다.For more information about handling events with delegates, see Handling and Raising Events.
