Hi , below is the sample byte code

                             oldText = objCitaqPrint.setWH('4');
                            System.arraycopy(oldText, 0, printText, iNum, oldText.length);
                            iNum += oldText.length;

                            oldText = objCitaqPrint.setBold(true);
                            System.arraycopy(oldText, 0, printText, iNum, oldText.length);
                            iNum += oldText.length;
                            oldText = objCitaqPrint.getGbk("Hello World \n");
                            System.arraycopy(oldText, 0, printText, iNum, oldText.length);
                            iNum += oldText.length;
                            
And this is how I pass data to cloud printer , printer is connected but it did not print anything 

Passing data to printer to print:   cloudPrinter.appendRawData(printText);
