Image forming system

An image forming system comprising:

• a server;
• a user terminal;
• and
• an image forming device, which are connected via a network, wherein
• the server includes:
• a server storage that stores print data uploaded in advance in association with user authentication information;
• and
• a code issuer that issues a code including the user authentication information,
• the server transmits the code in response to a request from the user terminal, and, when the user authentication information is received from the image forming device, acquires the print data associated with the user authentication information from the server storage and transmits the print data to the image forming device,
• the user terminal includes:
• a terminal display that displays various types of information to a user,
• the user terminal, when the code is received from the server, displays the code on the terminal display,
• the image forming device includes:
• a code reader that reads the code to acquire the user authentication information included in the code;
• a display that displays various types of information to the user;
• an operation acceptor that accepts a command of the user;
• and
• an image former that forms an image on the basis of the print data received from the server,
• the image forming device, when the code reader acquires the user authentication information, transmits the user authentication information to the server, when the print data associated with the user authentication information is received from the server, displays a print setting screen of the print data on the display, when the operation acceptor accepts a print setting from the user, displays, on the display, a print setting completion screen of the print data for which the print setting is reflected, and, when the operation acceptor accepts a print command of the print data, causes the image former to form an image based on the print data,
• the server storage stores print data uploaded in advance in association with group authentication information in which multiple pieces of user authentication are grouped,
• the code issuer issues a code including the group authentication information,
• the server, when the group authentication information is received from the image forming device, acquires the print data associated with the group authentication information from the server storage and transmits the print data to the image forming device, and
• the image forming device, when the print data is received from the server, displays a shared folder associated in advance with the group authentication information on the display, and, when the operation acceptor accepts a selection of the shared folder, displays a print setting screen of the print data on the display.
