Printing system, information processing apparatus and printing apparatus

An image processing apparatus comprising:

• a communication unit configured to communicate with a printing apparatus;
• and
• a controller,
• wherein the controller is configured to generate a first print job and a second print job to be transmitted to the printing apparatus through the communication unit, the first print job designating one of a plurality of sheet trays of the printing apparatus to be used when the first print job is executed, the second print job not designating any one of the plurality of sheet trays of the printing apparatus and requiring designation of one of the plurality of sheet trays through the printing apparatus when the first print job is executed.

A printing apparatus having a plurality of sheet trays configured to respectively accommodate sheets on which images to be formed,

• the printing apparatus comprising:
• a communication unit configured to communicate with an image processing apparatus;
• a image forming unit;
• an operation unit;
• and
• a controller,
• wherein the controller determines whether a print job which is received from the image processing apparatus through the communication unit is a first print job or a second print job, the first print job including a command designating a sheet tray to be used for printing, the second print job not including the command designating any sheet tray,
• wherein, when the receive print job is the first print job, the controller controls the image forming unit to form an image, based on the first print job, on a sheet accommodated in the sheet tray designated by the first print job, and
• wherein when the received print job is the second print job, the controller controls the image forming unit to form an image, based on the second print job, on a sheet accommodated in a sheet tray which is designated through the operation unit.
