本文實例為大家分享了C#條碼生成及打印的辦法，供大家參考，詳細內容如下

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

    //打印按鈕
    private void button1_Click(object sender, EventArgs e)
    {
      //實例化打印對象
      PrintDocument printDocument1 = new PrintDocument();

      //設置打印用的紙張,可以自定義紙張的大小(單位：mm).   當打印高度不確定時也可以不設置
      //printDocument1.DefaultPageSettings.PaperSize = new PaperSize("Custum", 585, 800);

      //注冊PrintPage事情，打印每一頁時會觸發該事情
      printDocument1.PrintPage += new PrintPageEventHandler(this.printDocument1_PrintPage);

      //開端打印
      printDocument1.Print();

      //打印預覽
      //PrintPreviewDialog ppd = new PrintPreviewDialog();
      //ppd.Document = printDocument1;
      //ppd.ShowDialog();
    }


    //打印事情
    private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
    {
      StringBuilder sb = new StringBuilder();
      sb.Append("\r\n\r\n\r\n");
      sb.Append("*******興隆超市*******\r\n");
      sb.Append("品名-----數量-----價錢\r\n");
      sb.Append("精品白沙  1    8元\r\n");
      sb.Append("張新發槟榔 1   10元\r\n");
      sb.Append("算計：   2   18元\r\n");
      sb.Append("---收銀員：張三---\r\n");
      sb.Append("---技術支持：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);

    }
