Print

require(["esri/widgets/Print"], function(Print) { /* code goes here */ });
Class: esri/widgets/Print
Inheritance: Print Widget Accessor
Since: ArcGIS API for JavaScript 4.2

The Print widget connects your application with a printing service to allow the map to be printed. It takes advantage of server-side, high-quality, full cartographic print functionality using the ExportWebMap service of ArcGIS, which can be configured with custom layout templates. One is provided that shows the map only, while another provides a layout with legend, etc. The Print widget works with the PrintTask which generates a printer-ready version of the map.

The Print widget has two required properties: view (reference to the MapView) and printServiceUrl (URL of the REST endpoint of the Export Web Map Task).

By default, the Print widget prints a localized date for all layouts except map-only. This can be customized using the customTextElements property of PrintTemplate.layoutOptions.

For more information about printing with the MAP_ONLY layout, please see exportOptions.

Known Limitations

No support

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.

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.
  • If the application and the print service are on the same origin, the name of the downloadable file can be customized with the fileName or title properties. If not, the name of the downloadable file will be generated by the ArcGIS Enterprise that hosts the print service.
  • 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.

allowedFormats String|String[]
Since: ArcGIS API for JavaScript 4.15

Specify the print output file format(s) that the user can select based on the options available from the print service. This property can take a string value or an array of string values.

When this value is "all" (default value), all the print service formats are available to be used. When an array of string values is used, only those values that match the options available from the print service will be used. If none of the input string values match those available from the print service, allowedFormats will fallback to default behavior.

Default Value:"all"

Example:
const print = new Print({
  view: view,
  printServiceUrl:
         "https://utility.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task",
  allowedFormats: ["jpg", "png8", "png32"]
});
allowedLayouts String|String[]
Since: ArcGIS API for JavaScript 4.15

Specify the print output layout(s) that the user can select based on the options available from the print service. This property can take a string value or an array of string values.

When this value is "all" (default value), all the print service layouts are available to be used. When an array of string values is used, only those values that match the options available from the print service will be used. If none of the input string values match those available from the print service, allowedLayouts will fallback to default behavior.

Default Value:"all"

});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});
// Specify an already-defined HTML div element in the widget's container

const basemapGallery = new BasemapGallery({
