Patent ID: 8493599

Claim:
A printing system including a first printing apparatus configured to execute printing using a first color material and a second printing apparatus configured to execute printing using a second color material in which a paper discharge unit of the first printing apparatus and a paper feed unit of the second printing apparatus are mutually connected, wherein the first printing apparatus comprises: a generation unit configured to generate first print data and second print data based on input print data; a transmission unit configured to transmit the second print data to the second printing apparatus; and a transporting unit configured to generate first image data by executing image processing on the first print data, to print the first image data on a sheet using the first color material, and to transport the sheet having the first image data printed thereon from the paper discharge unit, and wherein the second printing apparatus comprises: a second printing unit configured to feed, from the paper feed unit, the sheet having the first image data printed thereon and having been transported from the transporting unit, to generate second image data by executing image processing on the second print data that has been generated based on same print data as the print data of the first print data on the sheet, and to print the second image data using the second color material, and wherein the printing system comprises: a comparison unit configured to estimate first time required for printing the first image data and second time required for generating the second image data and to compare the estimated first time and second time, wherein the first printing apparatus starts printing of the first image data using the first color material without setting standby time in a case where the first time is longer than the second time, the first printing apparatus sets time until the second time passes to standby time and starts printing of the first image data using the first color material after the set standby time has passed in a case where the first time is shorter than the second time.
