A platen assembly for a printer includes a chassis to which there is mounted a printhead and a pair of bearing moldings supported by the chassis and movable toward and away from the printhead. A platen body is rotatably mounted between the bearing moldings and includes a platen surface extending therealong, a capping device extending therealong and a blotting device also extending therealong. Each device is selectively aligned with the printhead upon rotation of the body between respective angular orientation. The body includes end caps having cam surfaces engageable with a projection affixed to the chassis to cause movement of the bearing members toward and away from the printhead during rotation of the body so that the body does not damage the printhead.
