Zusammenfassung:To provide a printing device and the others which can improve efficiency in data transfer.SOLUTION: The printing device comprises: a main control circuit; a sub control circuit group, connected in series to the main control circuit, through which image data from the main control circuit are transferred from an upstream side to a downstream side; and a head group that is driven by the sub control circuit group. The sub control circuit group includes a k-sub control circuit and a k-1-sub control circuit connected to the upstream side of the k-sub control circuit (k is 2 or more integers). The image data include k-image data and k-1-image data. The main control circuit transmits the k-image data to the k-sub control circuit, and transmits the k-1-image data to the k-1-sub control circuit, after transmitting the k-image data.SELECTED DRAWING: Figure 4 【課題】データの転送の効率性を向上させることができる印刷装置等を提供する【解決手段】印刷装置は、主制御回路と、前記主制御回路に直列的に接続され、前記主制御回路からの画像データを上流から下流に転送する副制御回路群と、前記副制御回路群によって駆動されるヘッド群とを備え、前記副制御回路群は、第k副制御回路と、前記第k副制御回路の上流側に接続される第k-1副制御回路とを含み(kは2以上の自然数)、前記画像データは第k画像データ及び第k-1画像データを含み、前記主制御回路は、前記第k副制御回路に前記第k画像データを送信し、前記第k画像データを送信した後、前記第k-1副制御回路に前記第k-1画像データを送信する。【選択図】図4
