PrintDocument.PrintPage Event

Occurs when the output to print for the current page is needed.

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

public event PrintPageEventHandler PrintPage

To specify the output to print, use the Graphics included in the PrintPageEventArgs. For example, to specify a line of text that should be printed, draw the text using the Graphics.DrawString method.

In addition to specifying the output, you can indicate if there are additional pages to print by setting the PrintPageEventArgs.HasMorePages property to true. The default is false, which indicates that there are no more pages to print. 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. To print each page of a document using different page settings, handle the QueryPageSettings event.

To associate the event with your event handler, add an instance of the PrintPageEventHandler delegate to the event. The event handler is called whenever the event occurs. For more information about handling events with delegates, see Events and Delegates.

The following code example demonstrates handling the PrintPage event.

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

 public class PrintingExample : System.Windows.Forms.Form 
     private System.ComponentModel.Container components;

     private StreamReader streamToPrint;

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

    // The Click event is raised when the user clicks the Print button. 
    private void printButton_Click(object sender, EventArgs e) 
           streamToPrint = new StreamReader
              ("C:\\My Documents\\MyFile.txt");
              printFont = new Font("Arial", 10);
              PrintDocument pd = new PrintDocument();
              pd.PrintPage += new PrintPageEventHandler
       catch(Exception ex) 

    // The PrintPage event is raised for each page to be printed. 
    private void pd_PrintPage(object sender, PrintPageEventArgs ev) 
       float linesPerPage = 0;
       float yPos = 0;
       int count = 0;
       float leftMargin = ev.MarginBounds.Left;
       float topMargin = ev.MarginBounds.Top;
       string line = null;

       // Calculate the number of lines per page.
       linesPerPage = ev.MarginBounds.Height / 

       // Print each line of the file. 
       while(count < linesPerPage && 
          ((line=streamToPrint.ReadLine()) != null)) 
          yPos = topMargin + (count * 
          ev.Graphics.DrawString(line, printFont, Brushes.Black, 
             leftMargin, yPos, new StringFormat());

       // If more lines exist, print another page. 
       if(line != null)
          ev.HasMorePages = true;
          ev.HasMorePages = false;

       printButton.Text = "Print the file.";
       printButton.Size = new System.Drawing.Size(136, 40);
       printButton.Click += new System.EventHandler(printButton_Click);


    // This is the main entry point for the application.
