This is the printing code

                prl1.setText("Header");
                prl2.setText("-------------------------------");

                List<PrintedReceiptLine> printedReceiptLinesHead = new ArrayList<>();
                printedReceiptLinesHead.add(prl1);
                printedReceiptLinesHead.add(prl2);
 
                pr.setHeader(printedReceiptLinesHead);

                try {

How to use IPoyntReceiptPrintingService

Any Help on this matter would be highly appreciated .

Hi there,

can you give me the last 4 digits of your terminal serial #?
And can you post the rest of the code for your Activity or you can send me a private message?

Sorted it out, the Error message was because I didn’t handle the print listener call back properly.

Thanks @dennis for the concern.

@oximer There you go

     
     private String jobId = UUID.randomUUID().toString();
     PrintedReceipt printedReceipt = new PrintedReceipt(Parcel.obtain());

     List<PrintedReceiptLine> printedReceiptLinesHeader = new ArrayList<>();

     PrintedReceiptLine printedReceiptLine = new PrintedReceiptLine();
     printedReceiptLine.setText(String.format("%-31.31s", "Header Text"));
     printedReceiptLinesHeader.add(printedReceiptLine);
        
     printedReceipt.setHeader(printedReceiptLinesHeader);
      try {
                receiptPrintingService.printReceipt(jobId, printedReceipt, new IPoyntReceiptPrintingServiceListener.Stub() {
                    @Override
                    public void printQueued() throws RemoteException {
                        Snackbar.make(view, "PRINTING RECEIPT... PLEASE WAIT ", Snackbar.LENGTH_LONG).show();
                    }

                    @Override
                    public void printFailed() throws RemoteException {
                        Snackbar.make(view, "RECEIPT PRINTING FAILED,PLEASE CHECK IF PAPER HAS EXHAUSTED ", Snackbar.LENGTH_LONG).show();
                    }
                });
