An Epic system administrator must add the path to EpicROIHandler.ashx to the configuration for the Epic Print Service.
For example, if the virtual root for the Application Server is https://server/AppServer, then the path to EpicROIHandler.ashx should be entered as follows:
https://server/AppServer/EpicROIHandler.ashx
If Epic is communicating with the Application Server through the OnBase Web Server at https://server/AppNet, then the path to EpicROIHandler.ashx should be entered as follows:
https://server/AppNet/EpicROIHandler.ashx
