How to print a map.

DaveSouthern — Mon, 22 Dec 2014 18:47:36 GMT

I've been tasked with adding print functionality to our website. Specifically, we need to have a toolbar button that can be used to print the map - just the map - none of the other stuff on the page. I'm kinda new to web programming and arcGis and Javascript, so I'm not sure what to do. I found the following sample code, but I don't know if it's still valid (sometimes stuff goes stale).

https://developers.arcgis.com/javascript/jssamples/widget_print.html

In addition, I'm not sure how to alter the code to point to our maps instead of the 'sample' map in the code. Any assistance would be appreciated.

Hi Dave,

That sample is still relevant. Can you provide some more background on your map? For example, how was it created, i.e. JavaScript API, ArcGIS Online? Can you post the URL or code for the map?

This is a part of the app that I am not familiar with, so I may include too much (or not enough) code to answer your question. Our development framework is Asp.net 4.5 using the mvc model

<script id="MapConfig" type="text/javascript"  >
    //global map pointer
    var map;
    //get the default basemap
    //note that this can be overridden by the projection
    //[standard basemaps are not compatible with projected coordinate systems]
    require(["esri/map", "esri/layers/FeatureLayer", "esri/geometry/Extent", "esri/SpatialReference", "dojo/domReady!"], function (Map, FeatureLayer, Extent, SpatialReference) {
        //TODO: get the default extent for this feature
        var defaultZoom = null;
        defaultZoom = new Extent(-120, 0, 90, 40, new SpatialReference({ wkid: 4326 }));;
        @if (Model.TheLayer.Project.BaseMap == null)
        {
            @:map = createMap(defaultZoom, "topo", "locatorMap");
        }
        else
        {
            @:map = createMap(defaultZoom, "@Model.TheLayer.Project.BaseMap.MapCode", "locatorMap");
        }
        //add the project layers 
        loadProjectLayers(map);
        loadOutputLayers(map);
        //request the feature extent as our default zoom 
        var requestText = "/api/@Model.TheLayer.MapLayerSource.LayerType.ControllerName/GetGraphic" + "?MapFeatureId=@Model.TheFeature.Id.ToString()" + "&MapLayerId=@Model.TheLayer.LayerId.ToString()" ;
        require(["dojo/request/xhr"], dojo.hitch(this, function (xhr) {
            new xhr(requestText, { handleAs: "json" }).then(
                function (data) {
                   
                    //TODO: determine if we load geographic or projected data
                    var geometryParser = new geometryWktParser();
                    //parse the specified shape
                    var srid = '@Model.TheLayer.MapLayerSource.Dataset.MapProjection.ToString()';
                    var shape = geometryParser.loadShapeGeographic(data.WellKnownText, srid);
                    var projectedShape = esri.geometry.geographicToWebMercator(shape);
                    //apply to the map
                    map.setExtent(projectedShape.getExtent().expand(5));
                })
        }));
    })

function createMap(extent, baseMap, domHost) {
    //use the default dom host, if none specified
    if (!domHost) { domHost = "map";}
    //construct an esri map component
    var theMap;
    require(["esri/map"], function (Map) {
        theMap = new Map(domHost, {
            basemap: baseMap,
            extent: extent,
            sliderStyle: "small",
            sliderPosition: "top-right"
        })
    });
    return theMap;
}
</script>

Hmmm... I just tried 'View Live Sample' on the code page, and the page that is supposed to be running the sample is having problems on my system. It looks fine, but when you click the 'Print" button, nothing is sent to the printer - no printer dialog pops up or anything. Sometimes the 'print' button changes to a 'Printout' hyperlink, which navigates to another page with an image of the map. Is that how it's supposed to print?

Here is an example that still has the scalebar and date and map, but nothing else (also you can see a live example at Print a Map Just a click on the hammer icon and then the print icon and it will bring up a live print example):

Thanks so much for your response, Chris. I should have posted something sooner saying that my dev lead and I chose to go with a simple css media=print solution to this for now. However, I'll keep this code for the future in case I need it.
