Provided is a technique for allowing a user to easily check the status of an image scanning apparatus. An image scanning apparatus is configured to transmit original document image data by storing, sequentially in a buffer, line data obtained by line-by-line scanning of an original document and transmitting the stored line data to a host computer sequentially line by line, and includes a control unit configured to perform control to transmit original document image data including notification image data to the host computer in a case where it is detected that the apparatus status of the image scanning apparatus is not normal during processing executed in response to a scan command received from the host computer, the notification image data being a notification of an error occurrence.

An information processing apparatus for transmitting image data input by sequentially reading documents, with limiting an allowable frame size, includes: a transmission controller, wherein, in a case where the document has an irregular size, the transmission controller transmits the image data to a transmission destination in a preset frame of a first frame size until a rear edge of the document is detected, and if a portion, which is not transmitted, of the image data exists when the rear edge of the document is detected, transmits the portion to the transmission destination in a frame of a second frame size smaller than the first frame size so that the transmitting of the portion is finished before a start of transmission of image data corresponding to a next document.

An image forming system includes: a server; and an image forming apparatus, in which the server acquires divided-images obtained by dividing an original image, and provides the divided-images to the apparatus, acquires a dividing-printing-rule for determining which divided-image of the divided-images is printed at which position, and provides the rule to the apparatus, information on a divided-image to be printed and a printing position of the divided-image to be printed being described in the rule for each time when printing the image to be printed, and provides present time to the apparatus as time information, and the apparatus acquires the divided-images to be printed, the rule, and the time information from the server, selects, based on the time information and the rule, the divided-image to be printed from the divided-images and determines the printing position of the divided-image to be printed, and prints the selected divided-image at the printing position.
