The Advanced , Layout and Format options are not displayed in the Portal for ArcGIS Web AppBuilder Print Widget using ArcGIS for Server 10.2 synchronous Print Services when the application is created and opened in Google Chrome version 52.
Workaround 1. Use the ArcGIS for Server 10.3 or 10.4 Print Services.
Workaround 2. Use asynchronous Print Services.
Workaround 3. Create the application in a lower version of Google Chrome like 51. It then works fine in Google Chrome 52.
