摘要：
A data communication control apparatus controls data communication between at least one data processor, a reader which reads an image and outputs image data, and a printer which prints an image in accordance with the input image data. A connection controller controls a connection between the data processor, the reader and the printer, and a detector detects a connection request from the data processor. A discriminator discriminates whether or not the reader and the printer are in a copying operation, and a notification unit notifies the data processor of predetermined information.
