How can I use JavaPOS to print reciepts with an Epson printer?

by
  1. Get the Epson JavaPOS ADK from the Epson website, you’ll need to register to download it.
  2. Be sure you have a 32-bit JVM installed
  3. Install the Epson JavaPOS ADK
    • select 32-bit JVM
    • select option that lib files are copied to the jvm’s ext folder.
    • create a port for your printer
  4. In the installation folder: Epson/JavaPos/checkHealth can be used to check if your printer is connected correctly.
  5. Run Epson/JavaPos/setupPOS/setupPOS.exe, you will create a jpos.xml file which lets your java programm know which deviced are connected where and should be configured how.
    • Press new
    • Add your devices
    • Save the JPos.xml file
  6. You can test your installation with: http://sourceforge.net/projects/javapospostest2/ select there your newly created jpos.xml
  7. You can specify a specific path to your jpos.xml in Java with: System.setProperty(JposPropertiesConst.JPOS_POPULATOR_FILE_PROP_NAME, System.getenv("jposxml_path")); I used a system-enviroment variable but you can use of course any other way to specify the path.

Now you are ready to go!

Example: 

POSPrinterControl113 printer = (jpos.POSPrinterControl113) new POSPrinter();
CashDrawerControl113 drawer = (CashDrawerControl113) new CashDrawer();
try {
        printer.open("POSPrinter");
        printer.claim(100);

        printer.setDeviceEnabled(true);
    } catch (Exception e) {
        System.err.println("Printer deactivated " + e.getMessage());
        printerdisabled = true;
        drawerdisabled  = true;
        return;
    }
    try {
        drawer.open("CashDrawer");
        drawer.claim(100);
        drawer.setDeviceEnabled(true);
    } catch (Exception e) {
        System.out.println("Cashdrawer deactivated: " + e.getMessage());
        drawerdisabled = true;
        return;
    }
