I have an old MacBook Pro from 2011 - I have a new printer. The laptop and printer don't speak to each other. I have to open my Cloud and print from my icloud email. I got a notice I had bought my postage but don't see a link for the actual label. Where do you think the label is? I haven't had problems like this before. Am I looking in the wrong place? Is it at PayPal, Ebay, USPS, my downloads?
