Are either of you able to print using the default ArcGIS Server Print Service url (http://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%2...)?

I'm having a similar issue. I have the map preview and I click the big print icon. Then it asks which printer I want to use. But nothing gets printed. All my data is on local SDE except the basemaps.
