ShipStation is compatible with almost any 4" x 6" thermal label printer and 8.5" x 11" laser printer via USB.
However, for Mac users, we strongly recommend using a DYMO LabelWriter 4XL, as it is the only thermal printer that has a native Macintosh driver. (You can find instructions on how to install and configure the printer here.)
You may still use the very popular ZP 450 models, however, you may have some installation issues on a Mac because Zebra does not offer native Mac drivers for their printers. (Although we offer instructions on how to install and configure the Zebra thermal printer, please note that we cannot fully support or troubleshoot issues with Zebra printers.)
