According to my experience with three different printer brands; Brother, Dymo, and Munbyn. We must say that Munbyn 4x6 thermal labels are very durable and reasonable from all perspectives.
I have only ever used Zebra printers (since that's what FedEx Ship Manager and UPS WorldShip used to offer) and they are solid, reliable and easy to set up. They offer USB and Ethernet versions.
