2、错误原因

var LODOP; 

var print = function() {		
	printPage();
	LODOP.PRINT();
};
		
var printPage= function(){
		   
	LODOP=getLodop(); 
	LODOP.PRINT_INIT("用户表");
	LODOP.SET_PRINT_MODE("PRINT_PAGE_PERCENT","Auto-Width");
	LODOP.SET_PRINT_STYLE("FontSize",12);
	LODOP.SET_PRINT_STYLE("FontFamily","微软雅黑");
	LODOP.SET_PRINT_STYLE("Bold",0);
	LODOP.ADD_PRINT_HTM(50,10,"100%","100%",document.getElementById("user").innerHTML);
};

          点击打印时出现上述提示

3、解决办法

     由于没有安装LODOP打印插件，导致报错；下载CLodop_Setup_for_Win32NT_2.062.exe并安装
