Printing system

A printing system comprising:

• a first printing machine configured to print by ejecting liquid from a first printing section onto the front surface of a medium transported in a transport direction;
• a second printing machine provided downstream of the first printing machine in the transport direction and configured to print by ejecting liquid from a second printing section onto the rear surface of the medium transported from the first printing machine;
• and
• a control section, wherein
• when printing on both surfaces of the medium, the control section determines which of first print data and second print data is to be printed first by the first printing section, based on the print duties of the first print data to be printed on a first surface, which is one surface of the medium, and the second print data to be printed on a second surface, which is the other surface of the medium,
• the control section causes the first printing section to print whichever of the first print data and the second print data has the higher print duty, and causes the second printing section to print the other of the first print data and the second print data,
• the first printing machine includes a first medium accommodation section that accommodates the medium transportable to the first printing section,
• the second printing machine includes a second medium accommodation section that contains the medium transportable to the second printing section, and
• when printing print data on only one surface of the medium,
• when the print duty of the print data is equal to or greater than a set value, the control section causes the first printing section to print the print data on the medium transported from the first medium accommodation section, and
• when the print duty of the print data is lower than the set value, the control section causes the second printing section to print the print data on the medium transported from the second medium accommodation section.
