PURPOSE:To easily perform the replacement operation of a recording head by a user by allowing an ink jet recording apparatus to perform the operation concerned upon the reception of the transmission of the indication data related to operation data to transmit the operation concerned to a host means. CONSTITUTION:When the user of a data processing device selects the application of 'printer operation', the processing of a host part is started and the display of an operation menu is performed in a step S2701. The user looks this display to select desired operation by the predetermined key on a keyboard. In a step S2702, this selection is judged and, for example, when it is judged that the replacement of a recording head is selected, the step S2702 transfers to the processing in a step S2703. In the step S2703, for example, the display indicating the opening of a window is performed and the user inputs the completion of this operation by a key after the window is opened. The host part judges the input of this key input in a step S2704 and, in a step 2705, a head replacing command is transmitted to a printer part and the printer paret receives this command to start head replacing processing. |
