Line breaks is not being followed on printing in Kotlin

I am getting this format from a json string:

ABCDn EFG: HIJKLn 
MNO: PQRST nn
UVW: XYZ

When I print it, the line breaks (“n”) is not inserted. I get the Json string like so:

val orReply = gson.fromJson<OrReply>(decryptedValue, OrReply::class.java)
printReceipt(orReply.ORData)

and use this reply as so:

private fun printReceipt(orString: String) {
   printOnPrinter(orString)
}

Answer

Try the following function to process the line breaks and see if helps you in fixing the issue:

private fun processLineBreak(string: String) : String{
        return string.replace("n",System.lineSeparator())
}
