Abstract: In an image forming apparatus for reading a document image and forming the document image on a paper, document image data are divided into a plurality of blocks and the document image data are compressed in the unit of block to be stored in a first memory device. The data read from the first memory device are expanded in the unit of block to be stored in a second memory device. Compression time and expansion time are estimated and image output start time for a printer is set based on the compression and expansion times before expansion of all the blocks is completed. In a different way, the start time is set to read data from a second memory device by a printer for printing, after estimation based on expansion time on data not yet expanded by an expansion device. In a still different way, predetermined form data such as page number are superposed with image data. The form data is drawn first in a page memory device and expanded image data are superposed next in the page memory device. Print is started by taking drawing time of the form data into account.

Abstract: A facsimile apparatus having a printer function for local or remote printing out of image data from a computer, and a scanner device which reads an original document and produces corresponding image data for transmission and remote printing. A printer control device controls a connection with the computer to receive image data from the computer. Image device from the printer control device is processed using the same processing mechanisms as image data from the scanner device, and applied to a communication device capable of sending the image data in the form of facsimile data to a destination facsimile apparatus. The processing mechanisms include a memory which stores the image data from either the scanner device or the printer control device, and outputs the stored image data to the communication device for transmission as the facsimile data.
