What error does the browser give in the developers console and/or network(response)?
Is this a secure service?
I've never been able to print maps with points at all.
I get error
{"error":{"code":400,"message":"Unable to complete operation.","details":["Error executing tool. Export Web Map Task : Layer \"Address_Points\": Failed to create layer from service at https://blahblah/Address_Points/FeatureServer/0.\nFailed to execute (Export Web Map).\nFailed to execute (Export Web Map Task)."]}}
