How can I change the print options received from an ArcGIS print service to be more friendly and descriptive using the Esri sample print service?

Example uses the sample print service from arcgisonline. Note the find and replace on the layoutTemplate[0].choiceList; I added the dimensions of the templates from wikipedia, in particular for A4 / A3 paper sizes that are international/european so that it would be more obvious what they refer to. Apologize, I'm switching back and forth between dojo and jquery because I use some jquery plugins elsewhere. http://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task

<!-- html for print dijit -->
<div id='divDefaultPrint' style='text-align: center;'></div>

dojo.require("esri.dijit.Print");
dojo.require("esri.tasks.PrintTask");

function start() {
    // get print templates from the export web map task
    var printInfo = esri.request({
        "url": "http://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task",
        "content": { "f": "json" }
    });
    printInfo.then(handlePrintInfo, handleError);
}

function end() {
    printDijit.destroy(); // this destroys the divToAttachTo
    $parentDiv.append("<div id='divDefaultPrint' style='text-align:center;'></div>");
}

function handlePrintInfo(resp) {
    var layoutTemplate, templateLayouts, templateLabels, mapOnlyIndex, templates;

    layoutTemplate = dojo.filter(resp.parameters, function (param, idx) {
        return param.name === "Layout_Template";
    });

    templateLayouts = layoutTemplate[0].choiceList;
    templateLabels = dojo.clone(layoutTemplate[0].choiceList);

    //create two arrays with  1. layout labels to find, and 2. the replace text. Use corresponding index values.
    var f = ["A3 Landscape", "A3 Portrait", "A4 Landscape", "A4 Portrait", "Letter ANSI A Landscape", "Letter ANSI A Portrait", "Tabloid ANSI B Landscape", "Tabloid ANSI B Portrait", "MAP_ONLY"];
    var r = ["A3 Landscape - 16.54 x 11.69 (in)", "A3 Portrait - 11.69 x 16.54 (in)", "A4 Landscape - 11.7 x 8.3 (in)", "A4 Portrait - 8.3 x 11.7 (in)", "ANSI A Landscape 11 x 8.5 (in)", "ANSI A Portrait - 8.5 x 11 (in)", "ANSI B Landscape 17 x 11 (in)", "ANSI B Portrait 11 x 17 (in)", "Map Image (No Text) 8.3 x 11.46 (in)"];

     //create an array of regular expressions from find array
    var re = $.map(f, function (v, i) {
        return new RegExp('\\b' + v + '\\b', 'g');
    });

    //find and replace text
    $.each(templateLabels, function (i, val) {
        $.each(f, function (j, v) {
            val = val.replace(re[j], r[j]);
        });
        templateLabels[i] = val;
    });

    // create a print template for each choice
    templates = dojo.map(templateLayouts, function (ch, index) {
        var plate = new esri.tasks.PrintTemplate();
        plate.layout = ch;
        plate.label = templateLabels[index];
        plate.format = "PDF";
        plate.layoutOptions = {
            "authorText": "ORGANIZATION_NAME",
            "copyrightText": "COPYRIGHT",
            "legendLayers": [],
            "titleText": "APP_NAME",
            "scalebarUnit": "Miles"
        };
        return plate;
    });

    // create the print dijit with the templates
    printDijit = new esri.dijit.Print({
        map: vgis.app.map(),
        templates: templates,
        url: "http://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task"
    }, dojo.byId("divDefaultPrint"));
    printDijit.startup();
}

function handleError(err) {
    console.log("Printing failed: ", err);
}

You can set your custom values in the onPrintStart event (http://developers.arcgis.com/en/javascript/jsapi/print.html#onPrintStart)

for example:

 dojo.connect(printer, 'onPrintStart', function () {
                templates[0].layoutOptions.titleText = textBox.value;
 });

  • Yes, that would be another prior event during which you could change the values.
