Printing system

A printing system that outputs first elements and second elements to a bookbinding machine performing bookbinding of books by combining the first elements and the second elements, the system comprising:

• a first printing section including a first printing machine configured to print the first elements, the first printing section configured to output the first elements sequentially;
• and
• a second printing section including a second printing machine configured to print the second elements, the second printing section configured to output the second elements sequentially, wherein
• at least one of the first printing machine and the second printing machine is configured to receive printing order data indicating a printing order with regard to a plurality of jobs,
• the at least one of the first printing machine and the second printing machine is configured to perform printing referring to the printing order data so that an inserting order in unit of job to the bookbinding machine of the first elements output from the first printing section coincides with an inserting order in unit of job to the bookbinding machine of the second elements output from the second printing section,
• the first printing machine is configured to generate the printing order data indicating the printing order of the second elements based on a printing order at time of printing the first elements with regard to the plurality of jobs, and to output the printing order data to the second printing machine,
• the second printing machine is configured to print the second elements in the printing order indicated by the printing order data, and
• the first printing machine is configured to generate the printing order data, so that the inserting order in unit of job to the bookbinding machine of the first elements output from the first printing section coincides with the inserting order in unit of job to the bookbinding machine of the second elements output from the second printing section.
