I am using following code in my program to generate a bill to customer.
This code is working fine. But the problem is

"Printer not get stop until finishing that page". I want to stop the printer once it completes printing the data.
Please help me regarding this.

#region  OnPrintPage 
/// <summary>
/// Override the default OnPrintPage method of the PrintDocument
/// </summary>
/// <param name="e"></param>
/// <remarks>This provides the print logic for our document</remarks>
protected override void OnPrintPage(System.Drawing.Printing.PrintPageEventArgs e)
{
    // Run base code
    base.OnPrintPage(e);

    //Declare local variables needed
    
    int printHeight;
    int printWidth;
    int leftMargin;
    int rightMargin;
    Int32 lines;
    Int32 chars;

    //Set print area size and margins
    {
        printHeight = base.DefaultPageSettings.PaperSize.Height - base.DefaultPageSettings.Margins.Top - base.DefaultPageSettings.Margins.Bottom;
        printWidth = base.DefaultPageSettings.PaperSize.Width - base.DefaultPageSettings.Margins.Left - base.DefaultPageSettings.Margins.Right;
        leftMargin = base.DefaultPageSettings.Margins.Left;
        //X
        rightMargin = base.DefaultPageSettings.Margins.Top;
        //Y
    }

    //Check if the user selected to print in Landscape mode
    //if they did then we need to swap height/width parameters
    if (base.DefaultPageSettings.Landscape)
    {
        int tmp;
        tmp = printHeight;
        printHeight = printWidth;
        printWidth = tmp;
    }

    //Now we need to determine the total number of lines
    //we're going to be printing
    Int32 numLines = (int)printHeight / PrinterFont.Height;

    //Create a rectangle printing are for our document
    RectangleF printArea = new RectangleF(leftMargin, rightMargin, printWidth, printHeight);

    //Use the StringFormat class for the text layout of our document
    StringFormat format = new StringFormat(StringFormatFlags.LineLimit);

    //Fit as many characters as we can into the print area      

    e.Graphics.MeasureString(_text.Substring(RemoveZeros(curChar)), PrinterFont, new SizeF(printWidth, printHeight), format, out chars, out lines);

    //Print the page
    e.Graphics.DrawString(_text.Substring(RemoveZeros(curChar)), PrinterFont, Brushes.Black, printArea, format);

    //Increase current char count
    curChar += chars;

    //Detemine if there is more text to print, if
    //there is the tell the printer there is more coming
    if (curChar < _text.Length)
    {
        e.HasMorePages = true;
    }
    else
    {
        e.HasMorePages = false;
        curChar = 0;
    }
}
