You can use printooth library for any printer, printooth is simple and well documented, https://github.com/mazenrashed/Printooth

var printables = ArrayList<Printable>()
var printable = Printable.PrintableBuilder()  
    .setImage(image) 
    .setNewLinesAfter(1) // To provide n lines after sentence
    .build()
printables.add(printable)
BluetoothPrinter.printer().print(printables)

@Faxriddin Abdullayev `bitmap.scale(130, 130)` in Kotlin. – Sam Chen Feb 16 '21 at 16:58
