A Python Toolbox
Python toolboxes in ArcGIS are great. They’re even better then regular Python script in Toolboxes. Let me explain why and show you how to use an Python toolbox in a Print Service in ArcGIS for Server.
Since many years now, when you do any geoprocessing in ArcGIS for Desktop, you are able to incorporate a script in an toolbox in ArcMap or ArcCatalog. This enables you to do some more customizing if compared to the “drag-and-drop” modelling in toolboxes.
