前端使用lodop插件进行打印设置

 先前梳理了后台打印导出参考：https://www.cnblogs.com/yyk1226/p/9856032.html，但是没有显示出来打印预览页面。

本章使用Lodop插件进行打印设置，实现打印机设置功能。

效果展示：

点击打印之后，弹出【打印预览】效果，一旦连接到打印机，即可打印。

具体实现：

1.下载相关插件

 百度网盘下载地址：链接：https://pan.baidu.com/s/1WZsi6TPGjFj7PbAGW4ertg 密码：s375

 解压之后：

2.安装lodop

方式一：双击对应.exe可执行应用程序进行安装；

方式二：接下来讲到的，在jsp页面上提醒选择安装，因为有时候开发的东西是让客户使用的，不可能每次都得跟客户通知要安装哪些插件或者应用程序。

3.将解压后的文件放置在项目中，如图。

 4.修改LodopFuncs.js中相关路径。

5.修改LodopFuncs.js中注册信息的账号与密码。

 6.设计将打印的表格模板。（设计模板学习可以参考网上教程也可以自己摸索，上手很快）

7.设计完选择【生成程序代码】，进行复制。

8.将代码块粘贴到LodopPrint.js文件中，如下所示。

function PrintEntryOrder(data) {
    CreateEntryPrintPage(data);
}


function CreateEntryPrintPage(data) {
    var LODOP = getLodop();
    var rowMoveDown = 186;
    var lineMoveDown = 176;
    var rowHeight = 30;
    var lineHeight = 30;
    var x = 0;
    var y = 0;
    var list = 0;

9.在jsp页面调用该打印方法，并传输动态值。

点击按钮：

<input type="button" class="layui-btn" onclick="javascript:print();" value="打印" />

引入js：

<script type="text/javascript" src="js/lodop/LodopFuncs.js"></script>
<script type="text/javascript" src="js/lodop/LodopPrint.js"></script>

执行方法：

function print() {
        var data = $("#data").val();//获取后台传输过来的data值（此处不罗列后台代码）
        if (data) {
            PrintEntryOrder(JSON.parse(data));
        }
    }

打印设置完成！接下来打印试试！
