I am using an ipad, mpop and the mpop barcode reader for my POS system. I can never just scan a barcode, every time I want to use the barcode scanner, I have to go to the drop down menu, hit settings, hit printer and cash drawer and then wait for the mpop to reload to "online" and then I can scan. It then drops out for the next sale and I have to redo this process. How can I get it to just work automatically. I have read the instructions for both the barcode scanner and neto, nothing works.
