如何使用C#在纸张背面发送要打印的特定文本？

using System;
using System.Drawing;
using System.Drawing.Printing;

class Program
{
    static void Main(string[] args)
    {
        // 设置打印文本内容
        string textToPrint = "这是要打印的特定文本内容";

        // 创建PrintDocument对象
        PrintDocument pd = new PrintDocument();

        // 设置PrintPage事件处理程序
        pd.PrintPage += new PrintPageEventHandler(PrintPageHandler);

        // 执行打印操作
        pd.Print();
    }

    private static void PrintPageHandler(object sender, PrintPageEventArgs e)
    {
        // 获取要打印的文本内容
        string textToPrint = "这是要打印的特定文本内容";

        // 设置字体和打印位置
        Font printFont = new Font("Arial", 12);
        PointF printLocation = new PointF(e.MarginBounds.Left, e.MarginBounds.Top);

        // 设置打印背面
        e.PageSettings.PrinterSettings.Duplex = Duplex.Vertical;

        // 绘制文本内容
        e.Graphics.DrawString(textToPrint, printFont, Brushes.Black, printLocation);
    }
}
