PROBLEM TO BE SOLVED: To prevent the required printed matter from being mixed in the other printed objects and being missed by refusing the reception of a printed matter from a non-intended party. SOLUTION: This device 100 is constituted so as to perform printing on the basis of a print job signal transmitted from a data processor. In this case, printing permitted transmission sources are registered in register means 111 and 112, a discrimination means 113 discriminates whether the transmission source is registered or not from the received print job signal and only when the transmission source is registered, printing is executed by a printing means 110.
