Java POS打印机错误

我是Java的新手，我正在使用java开发POS应用程序。

我为这个项目买了一台爱普生POS打印机。 打印机型号为EPSON TM-U220.

我已经安装了JavaPos和我的代码片段，如下所示。 但是在运行时我得到了这个错误。

感谢是否有人可以帮我解决这个问题。

这是jpos.xml文件

我已经解决了我自己:)现在它工作正常。 感谢Joop试图帮助我。

这是我的解决方案。

1. 设置执行APD_455dE.exe的打印机驱动程序

2. 设置Epson_JavaPOS_ADK_11317

3. 使用SetupPOS.exe生成Jpos.xml（通常位于C：\ Program Files \ EPSON \ JavaPOS \ SetupPOS \ SetupPOS.exe）

4. 将Jpos.xml保存在src文件夹中

5. 将以下jar文件添加到项目epsonJposService182.jar epsonJposServiceCommon.jar jpos18.jar xercesImpl.jar xml-apis.jar

6. 使用以下代码System.setProperty（JposPropertiesConst.JPOS_POPULATOR_FILE_PROP_NAME，“D：\ Test \ Jpos_Sample \ src \ jpos.xml”）为项目指定Jpos.xml文件;

7. 准备好出发…！！！！
