I have a WAB application that we have set up to use a custom printing service. It works great but because the printing service has a legend, we don't need to "include legend" in the print widget. The advanced settings in the widget has a check box that by default, is checked on to include a legend. I am looking for a way to turn that off so users don't have to know to do that. It's not intuitive since they don't know that there is already a legend included in the layout.
