Hi dear Emma, 

Thank you for your quick replay, our version of QB desktop is 2017.
 Actually we are a single currency co. which is BHD, therefor even our customer/suppliers are BHD currency, unfortunately when we setup the system we did not notice that we have to change the currency from US to BHD at that time (now it's unchangeable, see the attached file) . that is why now we are facing this problem because we want to start print the documents from the system.
