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()。

代码实现

1、定义窗体，设置宽度和高度


<body onload="window.external.Print(0,0);" style="margin-top:0px;" >    <form id="form1" runat="server" >      <div align="center" valign="top" id ="PrintDoc" >                           <table style="width:4.8cm; height:9.9cm; border-width:1px; border-color:Red; border-style:dashed" >                        <tr align="center" valign="top">                        <td>                        <asp:Label id="Label_proname" runat="server" >                                  </asp:Label>                                                           </td>                        </tr>                        </table>                </div>          </form></body>

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

 <style media="print">.Noprint { DISPLAY: none }</style>

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);        }
    }
