By default, ArcGIS portals (including ArcGIS Online) allow cross-domain requests using CORS. If you configure the Organization | Settings | Security | Allow Origins setting in the portal that you use with VertiGIS Studio Printing, then you must add VertiGIS Studio Printing as an allowed origin.

The origin to allow depends on your deployment:

▪ArcGIS Online with Cloud Printing: If you use ArcGIS Online with cloud Printing and your organization has configured the Allow Origins setting in ArcGIS Online, then you must add apps.vertigisstudio.com as an allowed origin.

▪ArcGIS Online with On-Premises Printing: If you use ArcGIS Online with on-premises Printing and your organization has configured the Allow Origins setting in ArcGIS Online, then you must add your VertiGIS Studio Printing server as an allowed origin.

▪On-Premises Portal for ArcGIS with On-Premises Printing: If you use an on-premises portal with on-premises Printing and your organization has configured the Allow Origins setting in your portal, then you must add your VertiGIS Studio Printing server as an allowed origin.
