现在就是指的是在WEB中实现的那个页面中的代码我不知道要怎么用了，期盼各位大佬了！！

web里面实现打印不是在后台写代码的，你应该写脚本或者借助一些插件来实现它，最常用的是IE的WebBrowser和javascript，例如这样（不过这只能支持一般的IE打印，如果需要更加强大的功能的话最好是找一个合适的插件）
<OBJECT classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2" id=wb name=wb ></OBJECT>
<input type='button' value='打印' onclick='javascript:wb.ExecWB(6,1)'/>
<input type='button' value='打印预览' onclick='javascript:wb.ExecWB(7,1)'/>
<input type='button' value='页面设置' onclick='javascript:wb.ExecWB(8,1)'/>
