A printing device has multiple finishing functions and multiple e-mail accounts on a mail server in a network. When the brake is actuated, brake disk exerts a frictional force on the brake lining pressed against it, which urges the lining in the direction of an increasingly narrow gap between the ramps and the brake disk to exert a contact pressure that is in addition to that exerted by an actuation device to attain self-boosting. The two enhancement materials combine through the porous media to provide a luminescent background for the indicia printed on the media. Wordlines couple rows of memory cells of the array.
