Abstract: A data communication apparatus comprises a memory for storing plural data, a transmitter for transmitting the plural stored data, a display for displaying situations of the plural stored data, and a controller for performing, in case of displaying the situations, control to change order of display of the data being transmitted. Thus, the data being transmitted can be easily specified from among the plural stored data, the data being transmitted can be easily specified by changing display forms, the data being transmitted can be easily specified by shifting them to the head of a list and displaying this list, and the data being transmitted can be easily specified by automatically scrolling a display area thereof.

Abstract: This invention provides an environment in which, for example, even when the operation mode shifts to a specific one after a standby state for a predetermined time, a discharge tray corresponding to this operation mode functions to smoothly perform the next operation. For this purpose, if the standby state continues even upon the lapse of an auto-clear setting time, the operation mode shifts to a set specific one, and movement of a discharge tray corresponding to this operation mode is controlled.

Abstract: For an image processing apparatus that can execute a plurality of functions, a common area that can be shared by the individual functions is provided in addition to the memory areas that are prepared for these functions. During the printing process, a check is performed to determine whether the common area is available for use as a print buffer. When the common area is not available, an area prepared in advance as a print buffer is employed to print image data in a single buffer system. When the common area is available, a print buffer for at least one page is obtained in therein, and a plurality of print buffers are alternately accessed to develop and to output image data (double buffer system).
