How can I play the printer sound

[gsolorzanob]

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

https://github.com/AllInOneYT/react-native-thermal-printer/blob/9d5df0358f7e2306f25f730b334ce14743b091b5/android/src/main/java/com/reactnativethermalprinter/ThermalPrinterModule.java#L182

or here after printing https://github.com/AllInOneYT/react-native-thermal-printer/blob/9d5df0358f7e2306f25f730b334ce14743b091b5/android/src/main/java/com/reactnativethermalprinter/ThermalPrinterModule.java#L190

or both

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

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 https://github.com/DantSu/ESCPOS-ThermalPrinter-Android/issues/142 for more information
