Installation Linux Static Linking – Just link the lib (.a file) during the application building process. Dynamic Linking – Link and distribute the lib (.so file) with your executable file.

3.2

Windows Install the drivers package running EpsonFiscalDriver_01.09.00.exe. After that, OCX can be referenced and used by the application. The dynamic/static libraries (DLL and LIB) are used by the application in the same way as Linux ones. Note that, in all cases, EpsonFiscalDriver_01.09.00.exe should also be installed in the PC where the application is executed.

3.3

Android In your project add EpsonFiscalDriver.aar as dependencies and after that can be imported and used by the application. This is a mandatory import: import epson.epsonfiscaldriver.EpsonFiscalDriver.
