I'm having serious trouble trying to print a ticket on POS application I make a sell and when I validate the order (at the printint moment) send me this error:


TypeError: undefined is not an object (evaluating 'dict['pos'].dp')
undefined:137
Rastreo de error:

 I have a Posbox device during de sale process the printer goes online and barcode also but this is the error

I've been looking and everybody says to edit pos.xml but how can I edit those files (.js, .xml) even change the POS logo on this version how is this posible?
