Virginia E-File - Any paper forms required?

Toward the end of the instruction screens for e-filing of the Virginia return, there is an implication that there is a paper form that must be signed, and instructions will be provided after the e-file procedure has been completed, but no such instructions are given. Is there a requirement for submission of physical signatures, Forms W-2 and 1099, or any other paper forms if the Virginia return is e=filed?
