Only supported if the ArcGIS Portal an agency is using has access to their map services.
Requires an ArcGIS 10.4+ Print Service.
The printing service must have access to the services you want to print. If you have services hosted on a local intranet server, you cannot use the Printing service provided in ArcGIS Online. In this case you must use a local service.
Open the Lucity Administration Tool and go to GIS > GIS Services.
On the Utility Services tab look for the Printing Services section.
Enter the URL into the Printing Services section.
If the service is secured check the Service is Secure? The program will use the credentails associated to the first service listed on the Map Services tab.
