Printing apparatus and printing system

An apparatus for producing photographic prints based on specifications ordered by customers, comprising:

• an inputting section to input image data and associate data relevant to said image data, based on said specifications ordered by said customers, wherein said associate data include data of said specifications, and each of said associate data corresponds to at least one of said image data in a unit of each customer;
• a classifying section to classify said image data and said associate data into a first group for producing said photographic prints in a real-time and a second group for producing said photographic prints in an after-time, based on said data of said specifications included in said associate data;
• a first memory to store said image data classified in said second group;
• a second memory to store said associate data classified in said second group;
• an image forming section to form images on a recording medium, based on said image data and said associate data;
• and
• a controlling section to control a print producing process of said apparatus in either a first mode, in which said apparatus real-timely produces said photographic prints based on said image data and said associate data classified in said first group, or a second mode, in which said apparatus collectively produces said photographic prints based on said image data and said associate data classified in said second group, data of which are stored in said first memory and said second memory,
• wherein an operating time of said apparatus is divided into a first operating time and a second operating time, which are not overlapping of each other, and during said first operating time, said controlling section controls said print producing process of said apparatus in said first mode, while during said second operating time, said controlling section controls said print producing process of said apparatus in said second mode.
