Abstract
A printer has a controller unit and an engine unit, which are connected via a video interface. Upon reception of a designating command for designating a type of condition, whose condition change is to be reported, from the controller unit, the engine unit supplies a designated condition change signal to the controller unit immediately after the condition of the designated type has changed. The controller unit requests the engine unit to output detailed data associated with the status change in response to reception of the designated condition change signal.
