I'm printing a payment receipt from my app using the following:
new StaticPaymentPrintJob.Builder().payment(payment).build().print(context, account);
The payment receipt is printed successfully, but somehow the printer error is shown in the device and it keeps printing the same payment receipt until I delete the print job manually.
The printer queue only shows "Failed" in the reason section, and I see the following error shown in the Logcat.
onHandleIntent(PrinterIntentService.java:406)[IntentService[PrinterIntentService]]: print failed, printer: Printer{uuid=J76W2AB58HPAG, type=BAYLEAF_USB, name=Flex, mac=null, ip=null, category=RECEIPT}

The order being printed does not have any items. Should I add something in order to avoid this error?
The device being used is the Flex gen2 devkit device.
