Exception handling
A command transmission/reception API generates a propriety exception with an integer (int) type
parameter when an error occurs and notify the calling side of such an error.
Steps for Handling

byte[] data = str.getBytes();
int offset = 0;
int size = data.length;
int timeout = 5000;
int sizeWritten = 0;
int errStatus = IoStatus.SUCCESS;
try {
sizeWritten = mPort.write(data, offset, size, timeout);
} catch ( EpsonIoException e ) {
//Get error value
errStatus = e.getStatus();
