A facsimile server system which can be utilized similarly to a stand-alone FAX. A remote FAX includes a scanner, a printer and a FAX communication unit. A client delivers document data to a FAX server, and makes a request for FAX transmission/printing. The FAX server expands the document data requested to be transmitted, into image data, and it transfers the image data to the appropriate remote FAX and gives a command for the FAX transmission/printing. When instructed to perform FAX transmission directly by a user, the remote FAX accepts the image of a handwritten document, and it subsequently delivers the image data of the document to the FAX server and makes a request for the FAX transmission. Besides, when the remote FAX has been commanded to scan image data or has received image data as FAX reception, it delivers the scanned image data or the received image data to the FAX server. Then, the FAX server accumulates the image data and offers them to the client in accordance with a retrieval process.
