C#条码生成及打印实例代码

本文实例为大家分享了C#条码生成及打印的方法，供大家参考，具体内容如下

string BarcodeString = "13043404455";//条码
    int ImgWidth = 520;
    int ImgHeight = 120;

    //打印按钮
    private void button1_Click(object sender, EventArgs e)
    {
      //实例化打印对象
      PrintDocument printDocument1 = new PrintDocument();

      //设置打印用的纸张,可以自定义纸张的大小(单位：mm).   当打印高度不确定时也可以不设置
      //printDocument1.DefaultPageSettings.PaperSize = new PaperSize("Custum", 585, 800);

      //注册PrintPage事件，打印每一页时会触发该事件
      printDocument1.PrintPage += new PrintPageEventHandler(this.printDocument1_PrintPage);

      //开始打印
      printDocument1.Print();

      //打印预览
      //PrintPreviewDialog ppd = new PrintPreviewDialog();
      //ppd.Document = printDocument1;
      //ppd.ShowDialog();
    }

    //打印事件
    private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
    {
      StringBuilder sb = new StringBuilder();
      sb.Append("\r\n\r\n\r\n");
      sb.Append("*******兴隆超市*******\r\n");
      sb.Append("品名-----数量-----价格\r\n");
      sb.Append("精品白沙  1    8元\r\n");
      sb.Append("张新发槟榔 1   10元\r\n");
      sb.Append("合计：   2   18元\r\n");
      sb.Append("---收银员：张三---\r\n");
      sb.Append("---技术支持：李四---\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n");

      DrawPrint(e, sb.ToString(), BarcodeString, ImgWidth, ImgHeight);

    }

        {
          int PrintWidth = 175;
          int PrintHeight = 35;
          //绘制打印图片
