PROBLEM TO BE SOLVED: To provide a color printing device in which the cost thereof is prevented from being increased and the printing processing speed is increased in the tandem type color printing device. SOLUTION: Printing data outputted from a host computer 24 are outputted to an I/F controller 20 and after being converted to video data, they are outputted to LED heads 19Y-19BK through a head controller 22 and printed on a recording paper. While the video data are successively outputted to the controller 22 from the controller 20 in the meantime, a vertical synchronizing signal (VSYNM) and a horizontal synchronizing signal (HSYN) for outputting the video data are generated by a logic circuit 26. This generation processing of the signals is executed so that an error is not adjusted by outputting the signal (VSYNM) every color but the output of the signal (VSYNM) of the other color is adjusted by adjusting the reference timing of the signal (VSYNM) to the LED head of black (BK). Therefore, the device is provided with counters for respective colors, however, it is good that they are the single counter, respectively. |
