Excuse me, I installed JavaPOS1.12 in SLED11, on SurePOS 700 system, and jpos.xml was created, Control Center showed that POSPrinter was online and configured. after that, I tried to test the JAVAPOS, so I run the example program, and CashDrawer was normal, but POSPrinter had something wrong. when service.open() was called, Exception occurred, the exception message was "Device Service... Null Pointer" while service is not null. By the way, I found that jpos1122.jar is 722KB, but the jar package I downloaded from www.javapos.com is 542KB, and it will not work if I replace the jpos1122.jar with the one downloaded from www.javapos.com, why?? 3x
Both CashDrawer and POSPrinter work normally under Windows system.
