Print a Customer or Merchant Receipt

Follow these steps to print a customer or merchant receipt from a previous transaction:
  1. Retrieve the
    PrintCustomerReceiptIntent
     from the
    mposUi
     object and use the
    startActivity
     method to initiate the printing a receipt flow.
    // Use to print a customer receipt
val PrintCustomerReceiptIntent = mposUi.createPrintCustomerReceiptIntent(transactionIdentifier, false)
startActivityForResult(PrintCustomerReceiptIntent, MposUi.REQUEST_CODE_PRINT_CUSTOMER_RECEIPT)

// Use to print a merchant receipt
val PrintMerchantReceiptIntent = mposUi.createPrintMerchantReceiptIntent(transactionIdentifier, false)
startActivityForResult(PrintMerchantReceiptIntent, MposUi.REQUEST_CODE_PRINT_MERCHANT_RECEIPT)
  2. After the printing activity is completed,
    onActivityResult
     is triggered. This action returns information about the last transaction.
    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    "onActivityResult: $resultCode".logDebug(TAG)

    val parentLayout: View = activity!!.findViewById(android.R.id.content)
 
    if (requestCode == MposUi.REQUEST_CODE_PRINT_CUSTOMER_RECEIPT
        || requestCode == MposUi.REQUEST_CODE_PRINT_MERCHANT_RECEIPT) {

        if (resultCode == MposUi.RESULT_CODE_PRINT_SUCCESS) {
            Snackbar.make(parentLayout, "Printing success", Snackbar.LENGTH_SHORT).show()
        }
        else if (resultCode == MposUi.RESULT_CODE_PRINT_FAILED) {
            Snackbar.make(parentLayout, "Printing failed", Snackbar.LENGTH_SHORT).show()
        }
    }
