Second, the only scannable QR code I've ever seen has only been for Amazon returns. Never seen any other retailer or shipping service support that. (I'm sure there are, but it's by far the exception rather than the rule.)
Third, scanning a code at UPS etc. requires waiting in a line behind everyone else, which is often 10+ minutes. If you print your own label, you can just drop off.
