Faxed orders from doctors are preferred over telephone orders because they include the doctor's signature. This signature provides authentication and verification that the order is indeed coming from a licensed healthcare provider, ensuring the accuracy and legality of the instructions given.

Legibility, speed of communication, and immediate confirmation are important but do not carry the same level of significance as the doctor's signature in ensuring the validity and legal compliance of the orders.
