java实现标签打印-斑马打印机

背景

之前项目中有一个功能-批量打印资产标签，用户在设备资产界面勾选资产，选择打印样式，然后打印到标签纸上。花了两个星期后终于把

这个功能上线了，头皮屑都掉了不知道多少

初步设计

这里就说一下初步设计的思路。因需求可以总结为两种情况，一种是打印资产信息加条形码（资产编码生成），另外一种是资产信息加二维

码（资产编码生成），一开始的设计简单可以分为三张表:模板、字段以及模板和字段的关联关系表。前端利用html按照业务提供的标签纸

参数大小，把两种情况的样子画好定为样式一、样式二，类似如图然后新建模板，选择样式保存，然后在模板里面添加字段，字段详情里面可以设置数据来源字段或者来源sql，最后可以点击图片中的名

称、编号等位置弹出弹框，在弹框中绑定字段。后端处理时利用图片中位置所绑定的字段设置的数据来源字段或者来源sql去得到实际的数

据替换html中对应位置的数据，二维码或者条形码是用实际数据（实际场景都是资产编码这种）的base64编码去替换html中的img的

src。

这样就得到实际的资产信息标签的html了

然后把转换后的html生成pdf导出

后面去了客户现场，才看到了标签打印机，之前一直都是云开发。

然后打印机通过usb连上笔记本，下载驱动，点开之前生成过的pdf，右击打印

…打印出来的完全对不上，整个标签出来了半个外边的框框，其他东西都没有了，而且还横跨了两张标签纸。

然后开始调试，调试代码中纸张长宽，打印区域长宽，打印方向，打印机首选项中大小边距方向等。调了一天也没调出来，调到最后打印队

列里面显示已打印，但是实际上啥也没有了。

这时我是猜测pdf是太大了，超过范围就打不出东西，于是我拿标签纸和模板里的样式对比了一下，真的大了好多，于是我把实际的长宽给

了前端，前端反馈按照这个长宽样式画不出来，内容塞不下。。。后面我在代码里面尝试设置缩放也没弄出来

（生成的pdf大小都有一百多K，后面用第二种方式生成的pdf最多只有十几K）

着急的我第二天晚上在网上看到了斑马打印机的指令语言zpl，于是去看了zpl指令文档和一些类似的用zpl打印标签的博客

后一天运行写好的demo，利用驱动打印稍微调一调，就出来了像点样子的标签了。

这时候，我的思路就是使用zpl指令，把两种样式都定义好（后面用户调成了四种），实际场景中直接用资产信息去替换指令中对应的位置

就好了。

这时候我又找到了另一个神器–ZebraDesigner 2

用这个直接画好后可以直接打印，也可以生成zpl指令文档，完美，接下来就是在服务中完成代码了。

这中间主要的问题就是汉字问题

因为打印机中没有你设置的字体，所以打印出来的标签汉字不会显示，这里也看了网上蛮多方法都没有用，最后只好采取了汉字转图片打印

图片的方式

zpl指令转pdf打印

本地驱动打印很ok，但是服务器不支持这种方式，新的问题来了。由于这种斑马打印机不能联网，根据实际需求也不会给打印机装上很贵的

网卡。

所以只有一条路了，回到当初，导出pdf，客户自己本机打印pdf

zpl指令怎么转成pdf呢？

这里提供了接口供zpl指令转成pdf，只需通过http调用就好了，经测试ok

}本来想着提高效率通过list的并行流去http请求，但是没想到会报429，于是又改回了正常的循环。

最后，由于我这边是根据4个资产生成一个完成的zpl指令，然后得到一个pdf，实际场景中可能会选择许多资产，这样就会生成许多PDF，

存在一个pdf合并问题。

最后导出来的pdf非常完美，打印的效果也非常棒。
