The information processing apparatus is provided with a CPU for receiving an instruction for turning off power of the information processing apparatus. Upon receipt of the instruction, the CPU determines whether or not it is necessary to turn off the power of the information processing apparatus. When it is necessary to turn off the power of the information processing apparatus, the CPU controls the information processing apparatus such that the power thereof is turned off, whereas when it is unnecessary to turn off the power of the information processing apparatus, the CPU controls the information processing apparatus such that the power thereof is not turned off. ## Claims ### Claim 1 A printing apparatus of which power states include at least a normal state, a power saving state, a first turned off state, and a second turned off state, the printing apparatus comprising: a switch used by a user to turn off the printing apparatus, a storage device that stores a set of instructions;
