Do it using Print task

var printTaskURL = "<URL of Print Service>";
var templatePrint = new esri.tasks.PrintTemplate();
                templatePrint.format = "JPG";
                templatePrint.layout = "MAP_ONLY";                
                templatePrint.exportOptions = {
                    width: map.width,
                    height: map.height,
                    dpi: 96
                };
  var params = new esri.tasks.PrintParameters();
                params.map = map;
                params.preserveScale = false;
                params.currentExtent = map.extent;
                params.template = templatePrint;

var printTask = new esri.tasks.PrintTask(printTaskURL);

dojo.connect(printTask, 'onComplete', function (result) {
                   
                            window.open(result.url, "_blank");
                        
                });
                dojo.connect(printTask, 'onError', function (error) {
                  
                    alert(error);
                })
                printTask.execute(params);

I believe this sample serves your mission well. You can customize the template and output format with the print task.

Do make sure you get the proxy page right for this to work.
