A printing system has an interface unit (51) receivable for the first printing data for printing settlement-processing information and the second data for printing advertising and sales promotion information, and a plurality of printing apparatuses (50a, 50b) for print processing data obtained via the interface unit (51). When the interface unit (51) receives the first printing data, it transmits to the predetermined first printing apparatus (50a) among a plurality of printing apparatuses. When the interface unit (51) receives the second printing data, it determines if the second printing data is printable or not by the first printing unit (50a) and transmits the second printing data to the first printing unit (50a) or the second printing unit (50b) based on the determination result.
