Web使用热敏打印小票(IE环境)

在html页下使用Epson P60II 热敏纸下打印小票，使用的打印方案为调用window.print()。

1、定义窗体，设置宽度和高度

2、使用ActiveXObject，创建   Scripting.FileSystemObject​​​​​​​

function print_onclick() {
  var objfs = new ActiveXObject("Scripting.FileSystemObject");
  var objprinter=objfs.CreateTextFile("LPT1:",true);
  objprinter.Write(String.fromCharCode(0x1B) + "@");
  objprinter.Write(String.fromCharCode(0x1B) + String.fromCharCode(0x69));
  objprinter.Close();
}

3、设置隐藏模式打印

 .Noprint { DISPLAY: none }

4、填充数据​​​​​​​

 private void ListBind()
    {
        try
        {
            string strVoucherID = Request.QueryString["voucherid"];
            if (strVoucherID != null && strVoucherID != string.Empty)
            {
                this.Label_proname.Text = this.DataBase.GetShopVoucherDetail(strVoucherID);
                this.DataBase.VoucherPrintUpdate(strVoucherID, this.DataBase.Areaid);
            }

        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }

    }

    

    好牛网移动优惠卷
    .Noprint { DISPLAY: none }
 

function print_onclick() {
  var objfs = new ActiveXObject("Scripting.FileSystemObject");
  var objprinter=objfs.CreateTextFile("LPT1:",true);
  objprinter.Write(String.fromCharCode(0x1B) + "@");
  objprinter.Write(String.fromCharCode(0x1B) + String.fromCharCode(0x69));
  objprinter.Close();
}
  

             function PrintCutrefresh()
{
                print_onclick();
                  
             }
             setTimeout('PrintCutrefresh()',7000); //指定7秒后切纸
