Some, though not all, basemaps are being included in the printed (esri default print service) output legend from EB. For example, the imagery basemap will include 6 items, while the vector topo includes none. The non vector topo shows World_Hillshade in the legend. There is no symbology tile - just the text.
I haven't discovered anyway to control this in Map Viewer or EB (turning 'Show in Legend' off in Map Viewer basemap properties doesn't stick). Is there a solution to this - I don't need basemaps to show in the legend.
