Enable the Endicia module if you want to print labels with USPS postage. Without the Endicia module, your USPS labels will essentially just be address labels and will not have postage on them.

Non-ZPL Label Image Type: PR8 Update 8 added the ability to print adhesive backed labels using a Zebra or Zebra compatible printer. A Zebra compatible printer can be used with Endicia, FedEx, UPS, and Canada Post, but currently not with the USPS
Use Zebra Thermal Printing When Possible:
For some shipping destinations Endicia is not able to create a label that is compatible with a Zebra printer. If you enable the Use Zebra Thermal Printing checkbox, you also should select a value from the Non-ZPL Label Image Type, usually PDF. The Miva Merchant software automatically examines the label from Endicia. If the label we receive from Endicia is .zpl compatible, it will print on your Zebra printer. If it isn't .zpl compatible, it will print to the backup method you select in the Non-ZPL Label Image Type dropdown.
