INFORMATION PROCESSING SERVER, INFORMATION PROCESSING PROGRAM, AND INFORMATION PROCESSING SYSTEM

To effectively utilize information acquired from devices of other companies through an application program compatible with multi-vendors.SOLUTION: An information management server 100 according to the present invention includes an interface 190 capable of being connected to both a first terminal device 400 arranged so as to be able to output a first print command to a first printer 200 manufactured by a first manufacturer and a second terminal device 500 arranged so as to be able to output a second print command to a second printer 300 made by a second manufacturer. A processor 110 acquires a first total amount of print number of the first printer 200 during a predetermined period of time, acquires the print number of the first printer 200 based on the first print command from the first terminal device 400, acquires the print number of the second printer 300 based on the second print command from the second terminal device 500, and estimates, based on the acquired first total amount and the acquired print number based on the first print command, a second total amount of the print number of the second printer 300 during the predetermined period of time.SELECTED DRAWING: Figure 2 【課題】マルチベンダー対応のアプリケーションプログラムを介し他社デバイスから取得した情報を有効活用し役立てる。【解決手段】情報管理サーバ１００は、第１メーカ製の第１プリンタ２００に対して第１印刷指示を出力可能に構成された第１端末装置４００、及び、第２メーカ製の第２プリンタ３００に対して第２印刷指示を出力可能に構成された第２端末装置５００、の両方に接続可能なインタフェース１９０を有し、プロセッサ１１０は、所定期間における、第１プリンタ２００の印刷枚数の第１総量を取得し、第１印刷指示による第１プリンタ２００の印刷回数を第１端末装置４００から取得し、第２印刷指示による第２プリンタ３００の印刷回数を第２端末装置５００から取得し、取得された第１総量と取得された第１印刷指示による印刷回数とに基づき、所定期間における、第２プリンタ３００の印刷枚数の第２総量を推定する。【選択図】図２
