The label was / is actually for the regular Post Office (USPS) and unfortunately they won't have clue if you were to take it there without the label. Neither would UPS if I printed a label that way.
The label will have to be printed first. I have sent it to you again as just a JPG image. This should work. . . .let me know. The post office will have a small free box available that the label will work on.
