PROBLEM TO BE SOLVED: To provide a high speed printer in which the circuitry is simplified. SOLUTION: An up/down counter 40 performs counting based on a detection signal and an encoder signal, and a set signal generating circuit 421 and a clear signal generating circuit 431 deliver pulse signals to an HV signal generating circuit 441 when it gets to a specified count. The HV signal generating circuit 441 delivers a signal of "H" level as a print effective region signal HV1A upon receiving a signal from the set signal generating circuit 421 and delivers a signal of "L" level as the print effective region signal HV1A upon receiving a signal from the clear signal generating circuit 431. A delay circuit 451 delivers an output signal from the HV signal generating circuit 441 as a print effective region signal HV1B while delaying it by a prescribed count. The print effective region signals HV1A and HV1B are delivered to each dot array depending on the order of moving direction of a plurality of dot arrays arranged in a recording head.
