The short answer is that almost any scale will work with Printnode, but read on for details.
USB scales that implement the HID standard are supported. Many serial scales are as well.
Even if a scale is not on the list, it may work just fine with an existing setting. If not, PrintNode provides a utility that will capture the output of your scale. With that data, they can create a new setting for your specific scale. This process typically takes a few weeks.
PrintNode provides a list of supported scales, and some additional information, here:
