This article describes how to connect a label printer to your ShipHawk account using PrintNode.

PrintNode software is necessary because web-based applications like ShipHawk are not authorized to make automatic connections (such as print jobs) to physically installed hardware or client machines. PrintNode is a connector software program that allows ShipHawk to seamlessly communicate print jobs (labels, packing slips, pick tickets, and so on) to your locally or server-installed printers.

After successful setup, you can print labels and documents through ShipHawk from any supported browser.
