how to create a map layer legend graphics from the print function arcgis server 10.1

Dear All Expert

I want to print the graphics layer of a web application API javascript into a layout that I have set myself and then can display the map legend.

I attached the html source code that can be run in a web browser chrome which can be done to printing graphical layers and prints inPDF format.
