“Does this product use Efax???? I have to ask this question... if the pictures of the hp laserjet pro mfp m477fnw color all in one printer, do not show any ports for phone lines and the specifications do not state that it uses the efax software app... how exactly does this machine fax??? I see the manual shows ports for phone lines ... is it customary to post incorrect photos of the products? Baffled, can anyone supply an answer here?”
