    You will receive image id using both
    h:form and h:graphicImage tag id’s

    The Java script is : 

     function printImage()         
 {            
   var iamgeId = document.getElementById('fileViewerForm:imageViewer');

   var imagObject = new Image();
   imagObject = iamgeId;
   var originalImage = '<img id="imageViewer" src="'+imagObject.src+'" 
                        height="'+imagObject.height+'"
                         width="'+imagObject.width+'" />';

   popup =  window.open('','popup','toolbar=no,menubar=no,width=200,height=150');
   popup.document.open();
   popup.document.write("<html><head></head><body onload='print()'>");
   popup.document.write(originalImage);
   popup.document.write("</body></html>");
   popup.document.close();           
}

    JSF code is :

      <h:commandButton value="Print" onclick="printImage();"/><br>
       <rich:panel id="imageViewerPanel">                

            <h:graphicImage id="imageViewer" url="sampleImage.png"
                            value="sampleImage.png" width="200"
                                                     height="200" />
       </rich:panel>
  </h:panelGrid>

    It works on FireFox 3.0.18.
