I'm getting fed up going round in circles trying to justify this.

OK, we don't switch media. But when I press "print" or invoke the print 
method, a copy of the DOM is sent to the printer. If I have altered the 
DOM by adding elements or by changing the style property then I would 
like to be able to undo those changes before my DOM goes to the printer. 
It is not good enough to say that I should start messing about with 
classes and so forth or that it is bad practice to amend the style 
property directly. So long as I can do these things I want a way to undo 
them before my DOM is sent to a print device.
