A raster printing device comprises a base platform (310) configured to place a board to be printed, a movable device (340) configured to move above the base platform along a predetermined path, a first nozzle (320) and a second nozzle (330) fixed to the movable device side by side and facing the base platform, and a first chamber (360) and a second chamber (370). The first chamber is connected with the first nozzle and configured to spray out a first printing material (400) in the first chamber from the first nozzle. The second chamber is connected with the second nozzle and configured to spray out a second printing material in the second chamber from the second nozzle. The two nozzles in the printing device are arranged side by side so as to spray out different printing material respectively during printing, and therefore the phenomenon that an upper layer of pattern and a lower layer of pattern are staggered is avoided, in the meanwhile, printing two layers of pattern almost at the same time can be realized. |
