A: Open any order with USPS shipping which was added after installing and enabling the module. On top right you will see several buttons. One of those buttons is "Packing List".

Q: How do I pay for the postage when generating Labels?
A: There are two types of USPS Labels:

* With postage paid: It assumes that you use third-party company to pay for the postage to generate the label.
* Without postage paid: It assumes that you generate a label and then pay for the postage in the post office.

It is only possible to print the second type (without postage paid) of labels directly through USPS and our module does it.
To get access to USPS Labels API for this kind of postage payment, you need to specify explicitly in the request to USPS
that you are going to pay for the postage in the Post Office. And you will get the required access.
Email template for this is available in the module itself (if you click on the link under Labels option).
