An adapter unit for use with a host apparatus for sending and receiving document information to and from a remote terminal via a communication network. The host apparatus creates document information which may be facsimile data, teletex data or mixed mode data. The adapter unit comprises an interface unit connected to the host apparatus, a bit map conversion unit for converting teletex and mixed code data into bitmap data, a facsimile encoding unit, a facsimile decoding unit, a print interface unit connected to the host apparatus, a communication control unit, and a system control unit which controls transmission of the document information from the host apparatus to a remote terminal and reception of the document information from the communication network such that the document information from the host apparatus is transmitted in a form which the remote terminal is capable of processing. The received document information is supplied to the host apparatus for printing via the print interface unit after a conversion by the bit map conversion unit into bitmap data when the received document information is teletex or mixed mode data.
