PURPOSE:To eliminate variations in the printing position, by advancing the writing timing to make up for the delay in time between the reception of a signal with a CPU and the outputting thereof with a detector for an object to be printed. CONSTITUTION:An output signal S generated when a detector 7 for an object to be printed detects an object 8 to be printed is transmitted to a P:A4 and a measuring circuit 9 to measure the time length t1 spent until a CPU1 receives the signal S. A gate circuit 10 is provided to make the reception of a printing start command I at the CPU1 prior to the output signal T from a timer circuit 5. This eliminates the time awaiting the completion of processing by the CPU due to the time t1 and the output signal from the timer circuit 5. |
