Hi @Wade, are you talking about hidden layers displaying in the printed legend? If so, this is a known issue that was recently fixed. You can see the fix now using next, or wait for 4.22 to release (which should be later this week).

@Wade By default Print widget in JS API honors only the visible layers. I tested the sample and it is working fine. please check the screenshots Sandbox app with displaying he legends:

and the print generated from the app:

If you can provide more details on the requirements we can check.
