Java调用Zebra条码打印机打印条码、中英文数字条码混合标签，可自由控制格式和排版(2)

我在上一篇文章中介绍了Java调用条码打印机的相关方法，但是在实际生产环境中发现了一些问题，于是在此给出解决办法。

上一个Demo存在的一些问题包括：

1.打印浓度和宽度必须在打印机控制面板设置；

2.主机新添加的打印机获取不到；

3.严重：当某些中文字符无法打印时会终止程序。

4.添加了一个getMessage方法来获取打印结果。

第一个问题，只要在打印指令中加入~SDa和^PWa来控制打印深度和宽度即可。

第二个问题我采用了多种方法均无效，最终在一篇文章中偶然提到的一个在PrintServiceLookup.lookupPrintServices之前执行AppContext.getAppContext().put(PrintServiceLookup.class.getDeclaredClasses()[0], null)就能够解决问题。

第三个问题，通过try...catch捕获异常，并且替换掉这个无法打印的字符就行了。

完整的Demo如下
