Abstract: An image forming system including a print data management device and an image forming apparatus, the image forming apparatus receiving print data associated with a print job from a print data management device, if the print data is associated with a first operation and the print data management device is in an enabled state, receiving the print data from an information processing apparatus, if the print data is associated with a second operation, receiving the print data from the information processing apparatus, if the print data management device is in a disabled state, printing the print data associated with the print job on a recording medium, generating history information relating to the print job, the history information including identification information identifying whether the print job that has been printed is associated with the first operation or the second operation, and transmitting the history information to the print data management device.

Abstract: An image forming system includes: an information processing apparatus; a print data management device; and an image forming apparatus communicably connected each other. The print data management device includes a print data managing unit that manages and stores the print data transmitted from the information processing apparatus, a request print data transmission unit that transmits the print data to the image forming apparatus in response to a request from the image forming apparatus, a history information generating unit that generates history information for the print data, a history information acquiring unit that, from the image forming apparatus, acquires at least the history information added with the identification information from among the history information relating to print output stored in the storage medium of the image forming apparatus, and a history information managing unit that manages and stores the history information into the storage medium.
