An image forming system in which a plurality of user terminals that transmit a print job, a plurality of image forming apparatuses that execute a print job, and a managing server are connected via a network, wherein the managing server includes: a common queue that stores the print job transmitted from each user terminal, temporarily, a plurality of individual queues associated with the plurality of image forming apparatuses by one to one, an individual queue setting accepting part operable to receive from the each user terminal a queue name of the individual queue for each user; and register the queue name into individual queue setting information, a print job distributing part that distributes the print job stored in the common queue to the individual queue based on the individual queue setting information, a print job transmitting part that transmits the print job stored in the individual queue to the image forming apparatus associated with the individual queue, and an authentication part that performs a user authentication; wherein the individual queue setting accepting part (i) determines whether setting of the individual queue, which the user authenticated by the authentication part sets as a output destination of the print job in the individual queue setting information, is finished or not, and (ii) transmits, if the individual queue is not set to the output destination of the print job, a individual queue setting screen to the user terminal, and the each user terminal includes: a printer driver, a display part that displays the individual queue setting screen transmitted from the individual queue setting accepting part of the managing server, an individual queue setting part that transmits to the individual queue setting accepting part of the managing server the queue name of the individual queue selected by the user via the individual queue setting screen, and a print job generating part that generates the print job based on the printer driver and sends the print job to the common queue of the managing server. a common queue that stores the print job transmitted from each user terminal, temporarily, a plurality of individual queues associated with the plurality of image forming apparatuses by one to one, an individual queue setting accepting part operable to receive from the each user terminal a queue name of the individual queue for each user; and register the queue name into individual queue setting information, a print job distributing part that distributes the print job stored in the common queue to the individual queue based on the individual queue setting information, a print job transmitting part that transmits the print job stored in the individual queue to the image forming apparatus associated with the individual queue, and an authentication part that performs a user authentication; wherein the individual queue setting accepting part (i) determines whether setting of the individual queue, which the user authenticated by the authentication part sets as a output destination of the print job in the individual queue setting information, is finished or not, and (ii) transmits, if the individual queue is not set to the output destination of the print job, a individual queue setting screen to the user terminal, and the each user terminal includes: a printer driver, a display part that displays the individual queue setting screen transmitted from the individual queue setting accepting part of the managing server, an individual queue setting part that transmits to the individual queue setting accepting part of the managing server the queue name of the individual queue selected by the user via the individual queue setting screen, and a print job generating part that generates the print job based on the printer driver and sends the print job to the common queue of the managing server.
