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);

    }
