Hardware Access / Printing - Android SDK

Intro

How to use the internal printer on a supported pax device. This functionality is currently only available on the pax A960, A920 and A80 terminals.

Print Bitmap With Internal Printer

The following code snippet demonstrates how you can use the internal printer to print a bitmap on a supported pax device. We recommend to use a Bitmap width of 384px and bitmap config Bitmap.Config.RGB_565 to print the receipt.

        HardwareService paxService = new PaxService();
        PrinterStatusListener printerStatusListener = new PrinterStatusListener() {

            @Override
            public void onSuccess(EPrinterStatus printerStatus) {
                //Printing successful
            }

            @Override
            public void onFailed(EPrinterStatus printerStatus) {
                //Printing failed
            }

            @Override
            public void onError(Error error) {
                //Error while trying to print
            }
        };

        paxService.printBitmap(new Bitmap(), printerStatusListener, getBaseContext());

Print PaymentReceipt With Internal Printer

The following code snippet demonstrates how you can use the internal printer to print a PaymentReceipt when performing a transaction on a supported pax device.

        HardwareService paxService = new PaxService();
        PrinterStatusListener printerStatusListener = new PrinterStatusListener() {

            @Override
            public void onSuccess(EPrinterStatus printerStatus) {
                //Printing successful
            }

            @Override
            public void onFailed(EPrinterStatus printerStatus) {
                //Printing failed
            }

            @Override
            public void onError(Error error) {
                //Error while trying to print
            }
        };

        PaymentDelegate paymentDelegate = new PaymentDelegate() {
            @Override
            public void printMerchantReceiptAndSignature(PaymentReceipt receipt) {
                 printReceipt(paymentReceipt)
            }
    
            @Override   
            public void printCustomerReceiptAndSignature(PaymentReceipt receipt) {
                 printReceipt(paymentReceipt)
            }
    
            @Override
            public void printDccOffer(PaymentReceipt receipt) {
                 printReceipt(paymentReceipt)
            }
    
            @Override
            public void printJournalReceipt(PaymentReceipt receipt) {
                printReceipt(paymentReceipt)
            }
        };

        paymentService.payment(externalTerminal, payment, paymentDelegate);

        private void printReceipt(PaymentReceipt paymentReceipt) {
            new PaxService().printPaymentReceipt(paymentReceipt, printerStatusListener, getBaseContext());
        }
