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.

You could send this to the browser

   window.print();

It is up to the browser to decide what to do.

To print specific portions of the page, consider a print stylesheet. Using the media attribute allows you to make a certain file print only styles.

<link rel="stylesheet" href="/assets/css/print.css" media="print" />

You won't be able to print using javascript, since you can't manage hardware devices from the browser and it executes there.
