I use packing slips from outside ShippingEasy that are more attractive and contain much more information for the customer. Also, in order to get exact weights, my packages are packed and sealed before shipping labels are ever printed. Instead of printing a packing slip that I don't need with my shipping label, I'd like the option of substituting a shipping receipt with order information, tracking number, and postage paid for my own records. I know that this information is online, but there are times when a piece of paper is just a quicker option.
