ABSTRACT:
A facsimile section receives and decodes data transmitted through a communication line, converts the received data into dot image data line by line, and further performs resolution conversion of the data using a resolution converter. The data subjected to the resolution conversion is transferred to a printer section through a Centronics interface. When data of an entire line is all white, a white-skip command is transferred for that line. The printer section performs horizontal/vertical conversion of the transferred dot image data and data corresponding to the transferred white-skip command using a horizontal/-vertical converter, the converted data being stored in a scan buffer. When the scan buffer is full of the data for one scan, a recording head is driven to record an image. In an image communicating apparatus comprising the facsimile section and the printer section, the load of the control unit of the facsimile section can be diminished, and the time required for the recording can be reduced, with the above arrangement.
