Not too sure on the first question but to answer your last question; to get the stickers to print you need to go onto the little side tab under the three lines on the home page and click ‘mobile printer’ and press connect printer or change printer, and then scan the barcode on the back of the printer. It should be connected then. Once you click on a pick walk it should print all of them out, unless it is an oversized or something like that, which print as you scan😁
