Thanks for your reply Noah. I found where the error was. I am using secure services from my ArcGIS Online Organization and using token to authorize them in the code. When I authorize with IdentityManager like this then I have problem with print service: var tokenMap = { 'server': MapServiceUrl, 'token': myToken, }; IdentityManager.registerToken(tokenMap); Now I use the token on this way and don't have problem with the print service: var newTiledLayer = new ArcGISTiledMapServiceLayer(MapServiceUrl + "?token=" + myToken, { visible: false }); 2) About the print service, is it possible somehow to add my own Print Layouts? I have ArcGIS Online Organization and if I go to Organization -> Settings -> Utility Services here I have Printing but I can't add my print service and then add my Print Layouts. Is it possible with ArcGIS Online Organization to have my own Print Service with my Print Layouts or only possible for printing is to use yours with the default Print Layouts: https://utility.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task
