Export Web Map (Server)
Summary
This tool takes the state of a web application (for example, included services, layer visibility settings, and client-side graphics) and returns a printable page layout or basic map of the specified area of interest.
Usage
The input for Export Web Map is a piece of text in JavaScript object notation (JSON) format describing the layers, graphics, and other settings in the web map. The JSON must be structured according to the the ExportWebMap specification topic found in the ArcGIS Help.
This tool is shipped with ArcGIS Server to support web services for printing, including the preconfigured service named PrintingTools. The ArcGIS web APIs for JavaScript, Flex, and Silverlight use the Printing Tools service to generate images for effortless map printing.
For advanced printing scenarios, for example, swapping out service layers with local vector data, creating map books, and so on, you do not use Export Web Map at all; rather, you can use the ConvertWebMapToMapDocument() function in the Python arcpy.mapping module included with ArcGIS. To make your Python script available to a web application, you can expose the script through an ArcGIS Server geoprocessing service. For more information, see Printing in web applications in the ArcGIS Server help.

Web_Map_as_JSON |
A JSON representation of the state of the map to be exported as it appears in the web application. See the ExportWebMap specification to understand how this text should be formatted.
