Alex,

  Here is a code snippet that I use for the purpose of getting a map image:

var printTask = new PrintTask('your server ExportWebMap url');
        var template = new PrintTemplate();
        this.imgHeight = (740/oWid) * oHgt;
        template.exportOptions = {
          width: 1542,
          height: (1542/oWid) * oHgt,
          dpi: 200
        };
        template.format = "jpg";
        template.layout = "MAP_ONLY";
        template.preserveScale = false;
        template.showAttribution = false;

        var params = new PrintParameters();
        params.map = this.map;
        params.template = template;
        printTask.execute(params, lang.hitch(this, function(rsltURL){
            var mapImg = domConstruct.toDom('<img src="'+rsltURL.url+'" border="0" style="width:740px;height:'+this.imgHeight+'px;"/>');
            domConstruct.place(mapImg, dom.byId('mapImgDiv'), 'replace');
        }));
