在c# Windows窗体项目中，无法让打印机打印自定义大小的纸张

我最近一直在尝试在c#应用程序中打印表单。拍摄表格照片很容易，但我在打印部分卡住了。我读了很多文章和很多解决方案来打印自定义尺寸的纸张(我的意思是我的表格要打印在我为打印机指定的纸张上)，但遗憾的是没有一个成功。

到目前为止，我在我的项目中有:

//my method for taking a picture form the form , and then printing it .
void PrintImage(object o, PrintPageEventArgs e)
{
    int x = SystemInformation.WorkingArea.X;
    int y = SystemInformation.WorkingArea.Y;
    int width = this.Width;
    int height = this.Height;
    Rectangle bounds = new Rectangle(x, y, width, height);
    Bitmap img = new Bitmap(width, height);
   // e.PageSettings.PaperSize = new PaperSize("62mm", 244, (int)Size.Width) { RawKind = 259 };
    this.DrawToBitmap(img, bounds);
    Point p = new Point(0, 0);
    e.Graphics.DrawImage(img, p);
}
//getting the list of installed printers .  
private void comboBox1_Click(object sender, EventArgs e)
{
    comboBox1.Items.Clear();
    foreach (string printer in PrinterSettings.InstalledPrinters)
    {
        comboBox1.Items.Add(printer);
    }
}


   //Print Button Click event declaration 
    private void btnPrint_Click(object sender, EventArgs e)
    {
        PrintDocument pd = new PrintDocument();
        if (comboBox1.SelectedIndex !=-1)
        {
            pd.PrinterSettings.PrinterName = comboBox1.SelectedItem.ToString();
        }
        pd.DefaultPageSettings.PaperSize = new PaperSize("CardSize", 50, 50);
        pd.PrintPage += new PrintPageEventHandler(PrintImage);
        pd.Print();
    }

          PrintDocument pd = new PrintDocument();
          PaperSize paperSize = new PaperSize("MyCustomSize", 200, 200 ); //numbers are optional
           paperSize.RawKind = (int)PaperKind.Custom;
           pd.DefaultPageSettings.PaperSize = paperSize;
