The present invention related to a high-speed page wide printing method, comprising the steps of: providing a printing device and a medium, wherein the printing device at least comprises an ink-jet device including a plurality of odd-number ink-jet nozzles and a plurality of even-number ink-jet nozzles; the printing device receiving a printing order and the ink-jet device executing an ink-jet operation in response to the printing order; and the ink-jet device completing the ink-jet operation for completing a printing operation to a first printing region of the medium. Besides, the odd-number ink-jet nozzle and the adjacent even-number ink-jet nozzle of the ink-jet device form a set and are controlled by the same set of printing control data. Moreover, the ink injected through the plurality of odd-number ink jet nozzle is at least partially overlapped with the ink injected through the adjacent even-number ink-jet nozzle on the medium.
