Note: easiest setup would be to print your USPS labels via Rollo Ship Manager. You will receive commercial pricing and labels in a 4x6 format ready to print to Rollo.

We would  recommend using Rollo Ship Manager or another commercial solutions discussed in this article. With Rollo Ship Manager, USPS is a default shipping carrier and  prints your label in a 4 x 6 format using our negotiated shipment rates. They are online, user-friendly, and you can set them up in just minutes.
