I have noticed a problem on every custom print service I have encountered (or created): when using a custom Print (Geoprocessing) Service, any legend items that are in a group layer do not appear in the print-out's legend.
You can test this phenomenon with this example, specifically the layers in the Zoning group layer.
However, if using ESRI's default print service (http://utility.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%2...) these group layer legend items do show up in the print-out's legend.
Anyone have any idea on why this is or how to get the group layer legend items to show up?
