This article is a guide through the setup and formatting of your label printer. This article uses a Zebra printer as an example. If your label printer does not have an option to set your label size with these steps, we recommend you check the printer manual or the manufacturer's website for more information.

Hardware Setup:

  1. Plug your label printer into a power source.

  2. Ensure the label media is loaded properly: Down from the top and under the tabs.

  3. Ensure the label media is the correct type (2.25” x 1.25”, 2.25' x 4, etc).

  4. Press and hold the "Feed" button until the light flashes once, then release. One configuration label should print, and the light should remain solid. If not, there is a problem with the label media.
