官网：Js页面打印组件官网
可以通过此处进到lodop的官网，然后在官网上查询相关的参数方法，
所包含的方法函数如下：
● PRINT_INIT(strPrintTaskName)打印初始化
● SET_PRINT_PAGESIZE(intOrient,intPageWidth,intPageHeight,strPageName)设定纸张大小
● ADD_PRINT_HTM(intTop,intLeft,intWidth,intHeight,strHtml)增加超文本项
● ADD_PRINT_TEXT(intTop,intLeft,intWidth,intHeight,strContent)增加纯文本项
● ADD_PRINT_TABLE(intTop,intLeft,intWidth,intHeight,strHtml)增加表格项
● ADD_PRINT_SHAPE(intShapeType,intTop,intLeft,intWidth,intHeight,intLineStyle,intLineWidth,intColor)画图形
● SET_PRINT_STYLE(strStyleName, varStyleValue)设置对象风格
● PREVIEW打印预览
● PRINT直接打印
● PRINT_SETUP打印维护
● PRINT_DESIGN打印设计
可以根据以上函数实现页面的打印效果
可实现如下打印功能（仅展示部分js内容）
- 用代码实现打印页内功能
var LODOP; //声明为全局变量
function myPrint() { //直接打印
LODOP = getCLodop();
LODOP.PRINT();
};
function myAddHtml() { //打印预览
LODOP = getCLodop();
this.CreateOneFormPage();
LODOP.PREVIEW();
};
function CreateOneFormPage() { //打印页内想要展示的内容
LODOP=getLodop();
LODOP.PRINT_INIT("打印控件功能演示_Lodop功能_名片");
LODOP.ADD_PRINT_RECT(10,55,360,220,0,1);
LODOP.SET_PRINT_STYLE("FontSize",11);
LODOP.ADD_PRINT_TEXT(20,180,100,25,"郭德强");
LODOP.SET_PRINT_STYLEA(2,"FontName","隶书");
LODOP.SET_PRINT_STYLEA(2,"FontSize",15);
LODOP.ADD_PRINT_TEXT(53,187,75,20,"科学家");
LODOP.ADD_PRINT_TEXT(100,131,272,20,"地址：中国北京社会科学院附近东大街西胡同");
LODOP.ADD_PRINT_TEXT(138,132,166,20,"电话：010-88811888");
};
- 输出多页长文档及双面打印
//控制打印机自带双面打印(所谓自动双面)功能和纸张来源
SET_PRINT_MODE(“PRINT_DUPLEX”,2);0-不控制 1-不双面 2-双面(长边装订) 3-小册子双面(短边装订_长边水平)
SET_PRINT_MODE(“PRINT_DEFAULTSOURCE”,1);1-纸盒 4-手动 7-自动 0-不控制
var LODOP; //声明为全局变量
function DuplexPrint() {
CreatePrintPage();
LODOP.SET_PRINT_MODE("PRINT_DUPLEX",2);
LODOP.SET_PRINT_MODE("PRINT_DEFAULTSOURCE",1);
LODOP.PREVIEW();
};
function CreatePrintPage() {
LODOP=getLodop();
LODOP.PRINT_INITA(10,10,754,453,"打印控件功能演示_Lodop功能_多页文档");
LODOP.ADD_PRINT_TEXT(21,300,151,30,"自动居中的标题\n");
LODOP.SET_PRINT_STYLEA(0,"FontSize",15);
LODOP.SET_PRINT_STYLEA(0,"ItemType",1);
LODOP.SET_PRINT_STYLEA(0,"Horient",2);
LODOP.ADD_PRINT_TEXT(63,38,677,330,document.getElementById("doc1").value);
LODOP.SET_PRINT_STYLEA(0,"FontSize",15);
LODOP.SET_PRINT_STYLEA(0,"ItemType",4);
LODOP.SET_PRINT_STYLEA(0,"Horient",3);
LODOP.SET_PRINT_STYLEA(0,"Vorient",3);
LODOP.SET_PRINT_STYLEA(0,"TextNeatRow",document.getElementById("check0").checked);
LODOP.ADD_PRINT_LINE(53,23,52,725,0,1);
LODOP.SET_PRINT_STYLEA(0,"ItemType",1);
LODOP.SET_PRINT_STYLEA(0,"Horient",3);
LODOP.ADD_PRINT_LINE(414,23,413,725,0,1);
LODOP.SET_PRINT_STYLEA(0,"ItemType",1);
LODOP.SET_PRINT_STYLEA(0,"Horient",3);
LODOP.SET_PRINT_STYLEA(0,"Vorient",1);
LODOP.ADD_PRINT_TEXT(421,37,144,22,"左下脚的文本小标题");
LODOP.SET_PRINT_STYLEA(0,"ItemType",1);
LODOP.SET_PRINT_STYLEA(0,"Vorient",1);
LODOP.ADD_PRINT_TEXT(421,542,165,22,"右下脚的页号：第#页/共&页");
LODOP.SET_PRINT_STYLEA(0,"ItemType",2);
LODOP.SET_PRINT_STYLEA(0,"Horient",1);
LODOP.SET_PRINT_STYLEA(0,"Vorient",1);
};
- 打印条形码
var LODOP; //声明为全局变量
function prn_Preview() {
CreatePrintPage();
LODOP.PREVIEW();
};
function CreatePrintPage() {//绘制各种条形码
LODOP=getLodop(document.getElementById('LODOP1'),document.getElementById('LODOP_EM1'));
LODOP.PRINT_INITA(0,0,800,1600,"打印控件功能演示_Lodop功能_打印条码");

};
还有很多打印功能，比如：打印图片、强制分页并预览多页卡片、导出数据到Excel或图片文件、打印公章效果图等等，功能很强大
