PROBLEM TO BE SOLVED: To provide a highly reliable and economically excellent system in the case of printing on both side of successive paper by using two sets of one side printing devices for printing on the successive paper. SOLUTION: In this printing system, based on a paper feeding speed difference between a first printing device 1 and a second printing device 2, by predicting a time value (T) when a paper sheet reaches a smaller value of either of a first residence quantity margin value or a second residence quantity margin value, after starting to print by interlocking two sets of printing devices with each other, the printing and the paper feeding for the first printing device 1 and the second printing device 2 is respectively stopped when the printing time reaches the time value (T). |
