Abstract: A method and apparatus for calibrating a vacuum system in a printing device comprising obtaining a reference pressure value for a print zone of the printing device, measuring a calibration pressure value in the print zone of the printing device when the printing device is at an operating location and the vacuum system is in operation, determining an altitude based on the reference pressure value and the calibration pressure value and applying an operating setting to the vacuum system based on the determined altitude.

Abstract: In one example, a platen holder includes a surface to support a platen and a clamp to clamp the platen to the surface. The clamp includes a jaw and an actuator to open and close the jaw. The jaw and the actuator located below a plane of the surface and the jaw movable at the urging of the actuator between an open position in which the platen may be placed on or removed from the surface of the holder and a closed position to hold the platen against the surface.
