我所知道的web下的打印方法

一、
      1、在web页面上按照打印要求布置好页面
      2、打印函数：
              <script language="javascript">
                    function print()
                    {
                        bdhtml=window.document.body.innerHTML;
                        sprnstr="<!--startprint-->";
                         eprnstr="<!--endprint-->";
                         prnhtml=bdhtml.substr(bdhtml.indexOf(sprnstr)+17);
                         prnhtml=prnhtml.substring(0,prnhtml.indexOf(eprnstr));
                         window.document.body.innerHTML=prnhtml;
                         window.print();
                         window.close();
                       }
                    </script>
      3、将需要打印的部分用函数中sprnstr和eprnstr所定义的字符串包含
      4、调用print函数进行打印

二、使用MSDN上的一种方法可以打印多页自定义报表，具体查看

另：从ms新闻组中摘录：
使用WebBrowser控件打印Web页面时指定默认打印机，请参考下述代码：
<OBJECT id="WSNetwork" style="DISPLAY: none" classid="CLSID:F935DC26-1CF0-11D0-ADB9-00C04FD58A0B" VIEWASTEXT></OBJECT>
<OBJECT id="WebBrowser1" height="0" width="0" classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2" VIEWASTEXT></OBJECT>
 
  function Print()
  {
     var strCurrentPrinter = "\\\\Hu\\HuPrint";
     var strDefaultPrinter = "Smart Print";
     WSNetwork.SetDefaultPrinter(strCurrentPrinter);   
     WebBrowser1.ExecWB(6,6);  
     window.setTimeout("window.opener = null;window.close();",1500);
   }
