Description
The Print Dijit can be created with various print templates to specify different types of output from ArcGIS Server's Export Web Map Task. In this sample, print templates are created using info retrieved from the Export Web Map Task via esri.request.Note that this sample uses an ArcGIS Server export web map task.
The print widget is used in this sample. For more granular control over output from the ArcGIS Server 10.1 print service, use the printTask.
