The Priority Mail Express label layout displays the following:
A large letter "E".
The words "USPS Priority Mail Express®".
A tracking barcode.
Note: All Priority Mail Express shipments regardless of shape—such as Envelope, Letter, Large Envelope (flat), and so on—must print an Intelligent Mail package barcode (IMpb).
Select File > Printer Setup.
Select the printer that you want to use, and match the paper size to your label size.
For example, if you have a DYMO LabelWriter 4XL printer with a 4 × 6 label, select the Printer Paper Size of 1744907 4 in × 6 in. If you have a Zebra or Eltron printer with the two-part label 4 × 6.75 inches, select User Defined and enter a width of 4 and height of 6.75.
Select any delivery options and verify that your Sender Information is complete, including name, address, phone number, and email address (optional).
Note: Signature Required cannot be disabled for Priority Mail Express shipments when Adult Signature, COD, USPS insurance, or Hold For Pickup has been selected. Signature Required is turned on.
