Thank you for posting to our forums!
I'm sorry to hear you have had a rough start.
Once a label is paid for, the settings in the app are used to generate the PDF file of the label. If you need to make changes then the duplicate label process (How to: Create a unique duplicate label) creates a brand new PDF file, label, and tracking number.
The option to create a USPS SCAN form, from within ShippingEasy, is available to all paid plans: including Basic, Plus, Select, Premium, and Enterprise. Unfortunately, USPS SCAN forms are not available to Starter subscribers, from within ShippingEasy. You can, however, create a USPS SCAN form at Endicia.com using your ShippingEasy Endicia account information. The steps for doing that are provided in the link above.
If you have further questions, we have a wealth of information in our Support Center. If there is something you cannot locate there then you are welcome to post in our forums again or upgrade to a paid plan for one-on-one support. You can see what is included in each plan type here: What is included in my plan?
We hope you will give ShippingEasy another try!
