Java POS printer error

Tags: ,

I’m novice to Java, and I’m developing POS application using java.

I bought an Epson POS printer for this project. Printer model is EPSON TM-U220.

I’ve installed JavaPos and, my code snippet as follows. but when running I get this error.

Appreciate if anyone could help me with this problem.

I’ve solved it my own 🙂 and now it’s working fine. Thanks Joop for trying to help me.

Here is the solution worked for me.

  1. Setup Printer drivers executing APD_455dE.exe

  2. Setup Epson_JavaPOS_ADK_11317

  3. Generate Jpos.xml Using SetupPOS.exe (Usually located in C:Program FilesEPSONJavaPOSSetupPOSSetupPOS.exe)

  4. Save Jpos.xml in your src folder

  5. Add following jar files to your project epsonJposService182.jar epsonJposServiceCommon.jar jpos18.jar xercesImpl.jar xml-apis.jar

  6. Specify the Jpos.xml file to your project using following code System.setProperty(JposPropertiesConst.JPOS_POPULATOR_FILE_PROP_NAME, “D:TestJpos_Samplesrcjpos.xml”);

  7. Ready to go…!!!!

If any one need further assistance regarding POS printer issues contact me. I’ll try my best to help you guys.
