我转换控制位图，打印：

 使用（MemoryStream的毫秒=新的MemoryStream（））
{
    chart1.SaveImage（MS，ChartImageFormat.Bmp）;
    位图BM =新位图（MS）;

    PrintDocument的文档=新的PrintDocument（）;
    doc.PrintPage + =（S，EV）=＆GT;
    {
        ev.Graphics.DrawImage（BM，Point.Empty）; //调整此把图像别处
        ev.HasMorePages = FALSE;
    };

    doc.Print（）;
}

如何指定横向打印？

  doc.DefaultPageSettings.Landscape = TRUE;

I am converting a control to a bitmap and print it:

using (MemoryStream ms = new MemoryStream())
{
    chart1.SaveImage(ms, ChartImageFormat.Bmp);
    Bitmap bm = new Bitmap(ms);

    PrintDocument doc = new PrintDocument();
    doc.PrintPage += (s, ev) =>
    {
        ev.Graphics.DrawImage(bm, Point.Empty); // adjust this to put the image elsewhere
        ev.HasMorePages = false;
    };

    doc.Print();
}

How can you specify to print it in landscape orientation?

doc.DefaultPageSettings.Landscape = true;
