PROBLEM TO BE SOLVED: To provide a printing system capable of, when downloading and printing a receipt or a document or the like from the Web, guaranteeing the completion of printing, and inhibiting illegal additional printing or duplication.SOLUTION: A printing management device is configured to, when receiving a print request for a receipt or the like whose print destination has been designated from the terminal of a user (P1), confirm whether or not a designated printing device (MFP) has both an output guarantee function and a duplication inhibition function (P2, P3), and to, only when a confirmation result is positive, transmit the print data of the pertinent receipt for print to a printing device (P4), and to perform processing for inhibiting the duplicate printing of the same receipt (P8). The printing device is configured to, even when an obstacle such as powering-off occurs, print the requested receipt, and to inhibit duplication by synthesizing ground patterns.SELECTED DRAWING: Figure 2 |
