Please read the following considerations before printing a PB Presort label:

  • The label size, as specified in the documents.size field, uses an upper-case X. Using a lower-case x will result in an error.
  • If you choose to retrieve the label through a URL, the URL is available for 24 hours after the shipment is created.
  • By default, the APIs print ZPL2 labels using the Unicode character set. If you have an older printer that does not support Unicode, see this troubleshooting topic.
  • Advise shippers on correct label placement. Please see What is the correct placement for a shipping label?
