FIELD: information technologies.
SUBSTANCE: fiscal printer 1 comprises a detachable fiscal control circuit board 4, a fiscal board 8 installed on it, a real-time clock 10 and a circuit 15 to detect a fact of the fiscal control circuit board 4 extraction. The real-time clock 10 includes an input terminal 10b(1), where detection signals are input from the circuit 15, and a memory device 10c, which, as the signal of the fiscal control circuit board 4 withdrawal is input, memorises the data of this board 4 withdrawal and the time of the signal detection input, at the same time the data on withdrawal and the time of the signal input are associated with each other.
EFFECT: high extent of protection by means of reliable memorising and storage of data and time, when the fiscal control circuit board is extracted from the printer so that improper actions could be reliably detected.
