Abstract: A print method for using an image forming device to print an encrypted file transmitted from a terminal device includes a reception step in which a password of the encrypted file is received, a decryption step in which normal data is generated by decrypting the encrypted file using the password, a restriction setting step in which, based on the normal data, restricted data is generated which is set so as to restrict print processing, a restriction releasing step in which, based on an operation of a user with respect to the image forming device, the restriction of the restricted data is released so that to generate the normal data; and a printing step in which the normal data is printed using the image forming device.

Abstract: An image forming apparatus includes a data converting module, a communicating unit, a differential data obtaining module, and a combining module. The data converting module is configured to convert image data to displayed image data. The communicating unit is configured to send via a network the displayed image, and to receive an edited displayed image via the network which is edited based on the displayed image. The differential data obtaining module is configured to obtain differential data of at least a difference between the image data and the edited image data. The combining module is configured to combine the image data with the differential data into combined image data.
