An image processing apparatus comprising: a data processing unit such as a printing unit; a first interface having a plurality of logical channels for connecting with an external processing apparatus; a second interface, compliant with the same communication standard as the first interface and having a plurality of logical channels that have a different configuration from the first interface, for connecting with the data processing unit; and a control unit for controlling data transfer between the first interface and the second interface is provided. The control unit controls to acquire status information of the data processing unit via a first logical channel of the second interface in response to a request command of status information of the data processing unit which is received from the external processing apparatus via the first interface, and acquire status information of the data processing unit via a second logical channel of the second interface at predetermined timing regardless of existence/absence of a request command of status information from the external processing apparatus.
An image processing apparatus comprising:
A communication control method of an image processing apparatus including:

The present invention relates to registering and acquiring status information items in/from each function in an image processing system including a data processing terminal and an image processing apparatus having plural functions.
As a known facsimile apparatus connectable with a data processing terminal, such as a personal computer, there is a facsimile apparatus connected with the terminal through a two-way parallel port (compliant with IEEE 1284) interface, e.g., Centronics or the like, or a Universal Serial Bus (USB) interface, as disclosed in Japanese Patent Application Laid-Open No. 7-288625.
In an image processing system constructed with the aforementioned facsimile apparatus and data processing terminal, as a connection form between the facsimile apparatus and data processing terminal, a single logical interface is assigned to a single physical interface.
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
FIG. 1 is a block diagram showing a construction of an image processing apparatus according to an embodiment of the present invention;
FIG. 2 is a block diagram showing a construction of a processing apparatus according to the embodiment of the present invention;
A preferred embodiment of the present invention will now be described in detail in accordance with the accompanying drawings.
First, a brief construction of an image processing apparatus 100, which constitutes an image processing system according to the embodiment of the present invention, is described in detail with reference to FIG. 1.
In the image processing apparatus 100, a CPU 101 serving as a system control unit controls the entire image processing apparatus 100. ROM 102 stores control programs and an incorporated operating system (OS) program or the like, which are executed by the CPU 101. In this embodiment, each of the control programs stored in the ROM 102 realizes software controlling, e.g., scheduling, task switch and so on, under the control of the incorporated OS stored in the ROM 102.
