摘要： A printer, which can detect a media sheet type, includes: a light emitting source and a reflector, the light emitting source being capable of emitting light in a light emission direction towards the reflector, the reflector being arranged in light emission direction and being capable of reflecting light emitted by the light emitting source in a light reflection direction; a detector being arranged such that it can detect reflected light; and a controller connected to the reflector, the controller being capable of modulating a characteristic of the reflected light.
