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;

//LODOP.PRINT(); };
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！
