CHARACTER INFORMATION OUTPUT APPARATUS, PRINTING APPARATUS, PRINTING SYSTEM, CONTROL METHOD, AND PROGRAM

To make an optimum form of a character string including a partial character string represented by two or more consecutive arithmetic numbers in a vertical writing form.SOLUTION: A character information output apparatus includes a control unit 20 in which when an arithmetic number is included in a character string to be printed in a vertical writing form on a printing medium 13 by a printing device 1, in addition, when a character coinciding with a prescribed keyword 211 is adjacent to a front position or a back position of an arithmetic number in the character string, the arithmetic number is converted in a vertical writing form in to a form corresponding to the character coinciding with the prescribed keyword and output it to the printing device 1.SELECTED DRAWING: Figure 3 【課題】連続する２つ以上の算用数字で表される部分文字列を含む文字列の縦書きでの形態を、最適な形態となるようにする。【解決手段】文字情報出力装置は、印刷装置１により被印刷媒体１３に縦書きで印刷させる文字列の中に算用数字が含まれ、かつ文字列における算用数字の前方又は後方に所定のキーワード２１１と一致する文字が近接する場合に、その算用数字を所定のキーワードと一致する文字に応じた形態で縦書きに変換して印刷装置１に出力する制御部２０を備える。【選択図】図３
