由于公司一个地方需要用到图片转换ZPL格式去打印;这里的ZPL格式是打印斑马打印机,这里面有一些小的地方是需要注意的.
由于斑马打印机的型号不一样，设置不一样,外加自身的图片格式(.jpg,.png的不一样),图片的高度和宽度也不一样，就会直接导致打印出来的东西和你理想中的效果不一样，所以这里就需要设置图片的参数和斑马打印机自身的参数等设置。
然后下面贴出来图片转换为ZPL格式的代码,也可以当一个工具类来进行使用。

注意这里再重复下打印出来的效果不一样；导致的原因有可能:
1 : 斑马打印机型号问题
2 : 斑马打印机的参数设置问题
3 : 图片自身的类型和图片的高度宽度等参数信息的设置
由于公司一个地方需要用到图片转换ZPL格式去打印;这里的ZPL格式是打印斑马打印机,这里面有一些小的地方是需要注意的.由于斑马打印机的型号不一样，设置不一样,外加自身的图片格式(.jpg,.png的不一样),图片的高度和宽度也不一样，就会直接导致打印出来的东西和你理想中的效果不一样，所以这里就需要设置图片的参数和斑马打印机自身的参数等设置。然后下面贴出来图片转换为ZPL格式的代码,也可以当...
实现思路: 1、获取图片的二值化字节数组 这一步是关键 2、将字节数组转为十六进制 3、压缩十六进制字符串 结尾为1、0或者与上一行相同的;相同的连续字符压缩 4、拼凑ZPL编码，宽度需要扩大，因为需要时8个点(1字节)的整数倍
