Printing method and printing device

The invention provides a printing method and a printing device, in which printing quality can be maintained without increasing time necessary for printing even if resolution is enhanced. In the printing method, a reference signal is sent at intervals shorter than a minimum time interval at which an ink head provided with plural nozzles can eject ink, at least two reference signals set longer than the minimum time interval are counted as one count, the ink is ejected every one count, and a print pattern is formed by collectivity of the ejected ink. At least a final one count used to form the print pattern is adjusted so as to be lengthened by one or plural reference signals, and the ink is ejected every one count.
