I don't think anybody is suggesting that you write your answers out on paper, rather, create a text document with your answers and then attach this to your online form.
The only thing I would avoid is splitting your answers between the for and the attachment as it invites readers to just use the information in the form. Also, make sure that your full name and National Insurance Number is included on every page of the document.
