PrintTask
require(["esri/tasks/PrintTask"], function(PrintTask) { /* code goes here */ });esri/tasks/PrintTaskThe PrintTask generates a printer-ready version of the map using an Export Web Map Task available with ArGIS Server 10.1 and later. This class is used when you want to have more granular control over the user interface, for example, if you want to provide users the ability to define what appears on the printed page.
Use PrintParameters to set the printing options of the task.
Known Limitations
- There is no current support for printing SceneViews. Instead, see SceneView.takeScreenshot().
- VectorTileLayer printing requires ArcGIS Server 10.5.1 or later.
- For printing secure VectorTileLayers with ArcGIS Server 10.5.1 or 10.6.0, or for printing VectorTileLayers with ArcGIS Server 10.5.1 or any Printing Service published with ArcMap, the PrintTask will create a client-side image for the VectorTileLayer to use in the printout. This has some limitations related to large size printing quality and a dependency on browser window height/width ratio.
- Labels currently cannot be printed as part of a FeatureLayer with ArcGIS Server 10.5.1 or any Printing Service published with ArcMap.
- The print server does not directly print SVG symbols. Rather, they are converted to PictureMarkerSymbols for display.
- Make certain that any resources to be printed are accessible by the print server. For example, if printing a map containing PictureMarkerSymbols, the URL to these symbols must be accessible to the print server for it to work properly.

Method Details
- execute(params, requestOptions){Promise<PrintResponse>}
Sends a request to the print service to create a printable static image of the map using the options specified in the PrintParameters.
Parameters:params PrintParametersDefines the printing options.
requestOptions ObjectoptionalAdditional options to be used for the data request (will override requestOptions defined during construction).
Returns:Type Description Promise<PrintResponse> Resolves to an object containing the URL of the generated printout of the view. Example:var printTask = new PrintTask({ url: printUrl }); var template = new PrintTemplate({ format: "pdf", exportOptions: { dpi: 300 }, layout: "a4-portrait", layoutOptions: { titleText: "Warren Wilson College Trees", authorText: "Sam" } }); var params = new PrintParameters({ view: view, template: template }); printTask.execute(params).then(printResult, printError);
