又は、静止画及びキャラクタの合成かを、送信側通信端
末で任意に制御することのできる静止画伝送装置を得る
ことができる。従って、受信側通信端末が無人であって
も、送信側通信端末の操作者の判断で、受信側通信端末
のプリンタに、静止画及びキャラクタを夫々単独又は合
成してプリンタさせることができる。According to the present invention described above, whether the content to be printed by the printer of the receiving communication terminal is a still image and a character alone,
Alternatively, it is possible to obtain a still image transmission device capable of arbitrarily controlling the combination of a still image and a character with the transmitting communication terminal. Therefore, even if the receiving communication terminal is unattended, the printer of the receiving communication terminal can print the still image and the character independently or in combination with the printer at the discretion of the operator of the transmitting communication terminal.
