Receipt Print issue , Some time it works and some time it shows exceptions

I dont understand the behaviour of receipt printer .for some order it prints and some times it shows Null Pointer exception . Please help me to resolve this issue .

Why mac=null, ip=null these values are Null ?

print failed, printer: Printer{uuid=YRG4G36VKHW3G, type=SEIKOMINIUSB, name=Mini, mac=null, ip=null, category=RECEIPT} java.lang.NullPointerException at com.clover.engine.services.ReceiptPrinterPlugins.ReceiptGenerator.createReceiptView(ReceiptGenerator.java:2060) at com.clover.engine.services.ReceiptPrinterPlugins.ReceiptGenerator.createReceiptView(ReceiptGenerator.java:1608) at com.clover.engine.services.ReceiptPrinterPlugins.seiko.SeikoMini.printReceipt(SeikoMini.java:75) at com.clover.engine.services.PrinterIntentService.onHandleIntent(PrinterIntentService.java:325) at android.app.IntentService$ServiceHandler.handleMessage(IntentService.java:65) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:136) at android.os.HandlerThread.run(HandlerThread.java:61)

  1. for receipt printer , employee must be mapped with any order ?

Please ignore the mac=null, etc debugging statements. It's not relevant. Your print is failing at the point of generating the receipt content, not talking to the printer.

Without knowing what version of com.clover.engine you are running, I can't tell you specifically what's wrong. To answer your 1, and 2, I need to know what type of receipt you are printing and what code you are using to do so. Please Provide a pastebin link to your code.

What I really need is the version of the app com.clover.engine to match up the exception to to the code. Without knowing that, I suspect the problem is that you are asking to print a payment receipt but not specifying either a payment ID or a payment object in the print job.

Yes, the problem is you are using a payment print job, but not adding the payment. You need to call .paymentId() or .payment() on the builder.

Hey, we had this issue recently too. We found that for some reason the Order Object didn't have an "employee" assigned to it, so we just grabbed the Owners employee ID and added it to the Order Object before we tried to print it. Let me know if this helps.
