I am writing a webapp for my organization that needs to support printing through our local ArcGIS Server 10.1 instance. As long as I publish the service with Layout Templates Folder blank (to use the default templates) I have no problems, but if I give it the folder with our branded layout templates, the only "layout" I can use is MAP_ONLY – everything else times out, and no error is logged in the server. I've tried this using both the Print widget and PrintTask, with no success.
Edit: With Kelly Hutchins' help, I discovered that the print was eventually successful, but took too long to be recognized by the JS API. Is there anything I can check/change with our template documents to bring the processing time down to reasonable levels?
