The present invention discloses printing method and device. The printing method includes: obtaining grating image data, organizing the grating image data according to the arranging mode of the nozzlesin the bogie and buffer storing the data in the data transmission card, requesting data of the nozzle controlling board to the data transmission card according to the signal of the grating read headin the amount of one frame of image data for the bogie motion in one dot spacing, starting the high voltage pulse power source with the nozzle controlling board and printing one frame of image with the nozzles under the action of the high voltage. The present invention may be used in printing high resolution image and has less bogie reciprocating times and greatly raised printing speed.
