The 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.
For more information about printing with the MAP_ONLY layout, please see
exportOptions.
Use PrintParameters to set the printing options of the task.
Known Limitations
No support
- There is no current support for printing SceneViews. Instead, see SceneView.takeScreenshot().
- There is no current support for printing layer blending. Instead, see MapView.takeScreenshot().
- There is no current support for printing highlighted features. Instead, see MapView.takeScreenshot().
- There is no current support for printing ImageryLayers when a pixelFilter is defined.
- There is no current support for printing renderers generated from univariateColorSize.createContinuousRenderer() with an above-and-below theme.
- There is no current support for printing legend items for layers that are sent as a client-side image in the printout.
- There is no current support for printing features when using a renderer with
above-and-belowtheme.
Versioned support
- CIMSymbol cannot be printed with any Printing Service published with ArcMap.
- Labels currently cannot be printed as part of a FeatureLayer with ArcGIS Server 10.5.1 or any Printing Service published with ArcMap.
- ImageryLayer cannot be printed with ArcGIS Server 10.5.1 or earlier, or any Printing Service published with ArcMap.
- VectorTileLayer printing requires ArcGIS Server 10.5.1 or later.
- Printing layers rendered with the DotDensityRenderer will create a client-side image of the layer in the printout with ArcGIS Server 10.8.0 or earlier.
- 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.
- Printing the background color of a MapView or WebMap requires ArcGIS Server 10.9 or later.
Behavior notes
- Printing layers using clustering will create a client-side image of the layer in the printout.
- 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.

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.
Returns:Type Description Promise<PrintResponse> Resolves to an object containing the URL of the generated printout of the view.
