如何打印全角窗口窗体C#。？

using System.Windows.Forms;

private void Form1_Load(object sender, EventArgs e)
{
    // 在窗体加载时设置全角字符支持
    Console.OutputEncoding = System.Text.Encoding.GetEncoding("GB2312");
}

private void Form1_Paint(object sender, PaintEventArgs e)
{
    // 在窗体绘制时设置全角字符支持
    Console.OutputEncoding = System.Text.Encoding.GetEncoding("GB2312");
}

private void btnPrint_Click(object sender, EventArgs e)
{
    // 创建一个PrintDocument对象
    PrintDocument printDoc = new PrintDocument();
    
    // 设置打印事件处理程序
    printDoc.PrintPage += new PrintPageEventHandler(printDoc_PrintPage);
    
    // 调用Print方法开始打印
    printDoc.Print();
}

private void printDoc_PrintPage(object sender, PrintPageEventArgs e)
{
    // 在打印事件处理程序中绘制窗体
    this.DrawToBitmap(new Bitmap(this.Width, this.Height), new Rectangle(0, 0, this.Width, this.Height));
}
