When you make a capture of the web page is logical to not see anything that the user have type on it - Actually is not exist, you just make a load of the page, what you expect to see on text boxes ?

If you try to get a report for debug reasons and you won to see what happens on the page at the moment of the issue then you need to use a javascript library that build (as he can) the dom of the page and send it to you. All this actions request the user to make them - to capture the web page and send it with email, even if you can make it automate, the user must deride if he like to show you what have type on them.

An example http://experiments.hertzen.com/jsfeedback/ and the library http://html2canvas.hertzen.com/ that can capture what the user see on screen.
