Hey, I can't find how to play the beep sound while printing.

Any solution?

adding this two lines works for me

printerConnection.write(new byte[]{27, 66, 2, 1});
printerConnection.send(0);

Excuse me, where can I add these lines?

whetther here before printing

react-native-thermal-printer/android/src/main/java/com/reactnativethermalprinter/ThermalPrinterModule.java

Line 182 in 9d5df03

or here after printing

react-native-thermal-printer/android/src/main/java/com/reactnativethermalprinter/ThermalPrinterModule.java

Line 190 in 9d5df03

or both

The reason it is not included in the library is that printer sound is originally intended for warnings and errors.

Thank u, it works!!!

This sound is short. What the params for sound longer or volume greater?

you cannot change the volume of the sound as far as I know. refer to this issue DantSu/ESCPOS-ThermalPrinter-Android#142 for more information
