When they print the label is completely separate from when the package actually reaches UPS/FedEx/USPS, and often packages from big corporations get stacked up with all the other packages from that day. When the company picks up the packages, they might scan the packages, but given how many packages are likely shipped daily by Apple. It’s more than likely that they’ll be scanned in at the distribution center. Which shipper is it?

Edit: edited for clarity

You should get it within a day or two. If not, give 'em a call.
