  • Publication number: 20070035570
    Abstract: A recording head has a nozzle orifice line, and performs recording on a recording medium. A transport roller transports the recording medium to a position opposite to the recording head. A control unit has information about a plurality of speed levels different from each other which are rotational speeds for constant speed regions of the transport roller, a plurality of recording modes for leading end margins and information about recording start positions different from each other in each recording mode, and includes an optimum transport speed selecting unit that, when any one of the recording modes is selected, compares a first distance from a recording medium sensor to the recording start position with a second distance from a deceleration start point to a stop point, and selects the highest speed level when the second distance is smaller than the first distance.
