As Roadster noted, according to the rules the engineer is not supposed to copy forms while operating the engine. If you are going merrily down the track, your conductor is handy and he can copy, no problem.
If you are switching, there are three ways to handle it. If you feel you can safely copy the information AND if you feel there is no chance of anybody hiding in the weeds to catch you, you go ahead and copy, making sure that while you repeat it back you don't apply the brakes or something that would give you away. Another thing is to make a production out of it, call your conductor and tell him you're going to stop the move so you can copy a form. This may slow down your production but it has the benefit that any officials who may be monitoring the radio hear the whole thing and figure you are being a a good boy and complying with the rules. Or you can just tell the dispatcher you are switching and you'll have your conductor call in for a form when he gets back to the engine.
