How can I print a certain block/part of a web page? Print option to look like Print Screen functionality.
Use css, with the media = print option.
Like:
<link rel="stylesheet" type="text/css" href="print.css" media="print" />
The blocks you don't want printed can set display:none.
See http://www.quackit.com/javascript/javascript_print.cfm
You can use javascript's window.print() to print the page. To restrict the printed content to a specific part of the page, you can create a print stylesheet (see http://www.alistapart.com/articles/goingtoprint/) that hides all but the desired content.
