Zusammenfassung:	To provide an image processing device, a control method of the image processing device, and a program that can receive power supply from the outside by executing negotiation for power transmission with a plurality of external apparatuses when the plurality of external apparatuses are connected via a USB connection unit.SOLUTION: A CPU 12 of a printer 1 requests power from a first external apparatus 41 via a first USB connection unit 31 by communication in accordance with a USB PD standard (S11). In response to determination that the requested power is not supplied from the first external apparatus 41 (S13: YES), the CPU 12 requests power from a second external apparatus 51 via a second USB connection unit 32 (S17).SELECTED DRAWING: Figure 3 【課題】複数の外部機器が複数のＵＳＢ接続部を介して接続された場合に、複数の外部機器と電力の伝送のためのネゴシエーションを実行することで、外部から電力供給を受けることが可能な画像処理装置、画像処理装置の制御方法、及びプログラムを提供すること。【解決手段】プリンタ１のＣＰＵ１２は、第１ＵＳＢ接続部３１を介して第１外部機器４１に対し、ＵＳＢＰＤ規格に準拠した通信により電力を要求する（Ｓ１１）。また、ＣＰＵ１２は、要求した電力が第１外部機器４１から供給されないと判定したことに応じて（Ｓ１３：ＹＥＳ）、第２ＵＳＢ接続部３２を介して第２外部機器５１に対し電力を要求する（Ｓ１７）。【選択図】図３
