Print

AMD: require(["esri/widgets/Print"], (Print) => { /* code goes here */ });
ESM: import Print from "@arcgis/core/widgets/Print";
Class: esri/widgets/Print
Inheritance: Print Widget Accessor
Since: ArcGIS Maps SDK 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 print 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). The widget can preserve map scale or map extent in the printout. By default, the map extent is preserved. Use TemplateOptions to preserve scale instead.

The Print widget prints a localized date for all layouts except map-only. If using a custom print service, then customTextElements are supported for each print template. Values found there will be populated in the Print widget under Advanced options. These values can be overwritten in the Print widget UI, or programmatically using the templateCustomTextElements property.

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

  allowedLayouts: ["a3-landscape", "a3-portrait"]
});

The ID or node representing the DOM element containing the widget. This property can only be set once. The following examples are all valid use cases when working with widgets.

Examples
// Create the HTML div element programmatically at runtime and set to the widget's container
const basemapGallery = new BasemapGallery({

  "esri/config"
], function(Print, esriConfig) {

  // ...

  view.when(function () {
    print = new Print({
      view: view,
      // specify your own print service
      printServiceUrl:
        "https://utility.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task"
    });

    // Add widget to the top right corner of the view
    view.ui.add(print, "top-right");

    // use a requestInterceptor to monitor the print widget
    // for print completion
    esriConfig.request.interceptors.push({

      // interceptor only applies to requests made to the print service URL
      urls: print.printServiceUrl,
      // use the AfterInterceptorCallback to interogate the exportedLinks property
      after: function(response) {

      }
    });
  });
extraParameters Objectinner
Since: ArcGIS Maps SDK for JavaScript 4.20

This option allows passing extra parameters (in addition to templateOptions) to the print (export webmap) requests.

headingLevel Number
Since: ArcGIS Maps SDK for JavaScript 4.20

Indicates the heading level to use for the "Exported files" text where users can access the exported map printout. By default, this text is rendered as a level 3 heading (e.g. <h3>Exported files</h3>). Depending on the widget's placement in your app, you may need to adjust this heading for proper semantics. This is important for meeting accessibility standards.

Default Value:3
See also
Example
// "Exported files" will render as an <h4>
print.headingLevel = 4;
iconClass String
Since: ArcGIS Maps SDK for JavaScript 4.7

The widget's default CSS icon class.

The unique ID assigned to the widget when the widget is created. If not set by the developer, it will default to the container ID, or if that is not present then it will be automatically generated.

includeDefaultTemplates Boolean
Since: ArcGIS Maps SDK for JavaScript 4.18

Indicates whether or not to include defaultTemplates.

Default Value:true
Example
const printWidget = new Print({
   view: view,
   includeDefaultTemplates: false,
   portal: {url: "https://.example.arcgis.com/sharing/"},
   container: "printDiv"
});
label String
Since: ArcGIS Maps SDK for JavaScript 4.7

The widget's default label.

portal Portal
Since: ArcGIS Maps SDK for JavaScript 4.18

It is possible to search a specified portal instance's locator services. Use this property to set this ArcGIS Portal instance to search. This is especially helpful when working with a custom print template.

If this property is set, it is not necessary to set the printServiceUrl property.

See also
Example
const printWidget = new Print({
   view: view,
   portal: {url: "https://example.arcgis.com/sharing/"},
   container: "printDiv"
});
printServiceUrl String

templateCustomTextElements Object[]
Since: ArcGIS Maps SDK for JavaScript 4.22

An object containing an array of customTextElements name-value pair objects for each print template in a custom print service. Use this property to update the text for custom text elements on the page layout.

The Print widget calls the Get Layout Templates Info task on the GPServer to discover possible customTextElements values for each template. The name of the task must match Get Layout Templates Info, templates must be published with customTextElements, and values must be strings. Values found there will be populated in the Print widget under Advanced options. These values can be overwritten in the Print widget UI, or programmatically using this property. To list all print templates available on the print service to see see which templates were published with customTextElements, use the effectiveTemplateCustomTextElements property.

Example
const printWidget = new Print({
   view: view,
   // specify your custom print service
   printServiceUrl: "",
   // `customTextElements` are defined per print template
   // this example has one template with `customTextElements`
   templateCustomTextElements: {
      // if there were more applicable templates, then we would
      // create another object with the template name containing
      // an array of more name-value pairs
      "Landscape_TextElements": [
         // the possible values are defined in the print service
         { "headquarters": "Foxborough, Massachusetts" },
         { "division": "AFC East" },
         { "founded": "1959" }
      ]
   }
});
templateOptions TemplateOptionsautocast
Since: ArcGIS Maps SDK for JavaScript 4.6

Defines the layout template options used by the Print widget to generate the print page.

Example
templateOptions: {
  title: "My Print",
  author: "Sam",
  copyright: "My Company",
  legendEnabled: false
}
view MapView

A reference to the MapView. Set this to link the widget to a specific view.

The view model for this widget. This is a class that contains all the logic (properties and methods) that controls this widget's behavior. See the PrintViewModel class to access all properties and methods on the widget.

visible Boolean inherited

Indicates whether the widget is visible.

If false, the widget will no longer be rendered in the web document. This may affect the layout of other elements or widgets in the document. For example, if this widget is the first of three widgets associated to the upper right hand corner of the view UI, then the other widgets will reposition when this widget is made invisible. For more information, refer to the CSS display value of "none".

Default Value:true
Example
// Hides the widget in the view
widget.visible = false;
