A communication apparatus includes a Content-Addressable Memory and packet processing circuitry. The handle assembly also includes a wand cap which is movable between a first position in which the wand cap covers the open end of the tubular wand and a second position in which the open end of the tubular wand is not covered by the wand cap. The base station is operable to communicate the mobile-terminated message to the mobile station. A measurement section measures a surface temperature of each of portions of the print medium supported by the platen.
