I'm trying to print using the built in PrintingTools geoprocessing service using 10.2.1, and everything is working well with one exception. I allow the user to select one or more polygons in the map, storing the graphics in a graphics layer. I want to print those polygons on the map, and the export web map specification http://resources.arcgis.com/en/help/main/10.2/index.html#/ExportWebMap_specification/0155000004w2000... indicates that client side graphics layer can be included. I've built the json in the proper format (at least the geoprocessing service accepts it and returns an image properly) but the graphics layer do not show up in the image.
