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

//==本JS是加载Lodop插件及CLodop服务的综合示例,可直接使用,建议看懂后融进自己页面程序==

var CreatedOKLodopObject, CLodopIsLocal, CLodopJsState;

//==判断是否需要CLodop(那些不支持插件的浏览器):==
function needCLodop() {
    try {
        var ua = navigator.userAgent;
        if (ua.match(/Windows\sPhone/i))
            return true;
        if (ua.match(/iPhone|iPod|iPad/i))
            return true;
        if (ua.match(/Android/i))
            return true;
        if (ua.match(/Edge\D?\d+/i))
            return true;

        var verTrident = ua.match(/Trident\D?\d+/i);

        var verFF = ua.match(/Firefox\D?\d+/i);
        var x64 = ua.match(/x64/i);
        if ((!verTrident) && (!verIE) && (x64))
            return true;
        else if (verFF) {
            verFF = verFF[0].match(/\d+/);
            if ((verFF[0] >= 41) || (x64))
                return true;
        } else if (verOPR) {

                return true;
        } else if ((!verTrident) && (!verIE)) {
            var verChrome = ua.match(/Chrome\D?\d+/i);
            if (verChrome) {
                verChrome = verChrome[0].match(/\d+/);
                if (verChrome[0] >= 41)
                    return true;
            }
        }
        return false;
    } catch (err) {
        return true;
    }
}

//加载CLodop时用双端口(http是8000/18000,而https是8443/8444)以防其中某端口被占,
//主JS文件“CLodopfuncs.js”是固定文件名,其内容是动态的,与当前打印环境有关:

以上是最基础的用法,vue框架同样可用,更复杂的话可以去官网查询用法,除了直接打印以外,还有预览打印等,以及其他控制打印的方法,功能还是挺多的,插件还是挺强大的,不过商用的话是需要买的,不然会有水印。
