Disclosed are a data processing method, an apparatus and an ink-jet printer. The method comprises the following steps: a processor sequentially receiving multiple lines of image lattice data; after receiving one line of image lattice data is complete, splitting the one line of image lattice data to n groups of image lattice data according to the number of lines of corresponding nozzles along a paper feeding direction of the one line of image lattice data, wherein n is the number of rows of all nozzles; after splitting the one line of image lattice data, writing the corresponding split n groups of image lattice data to an internal buffer; after writing the split n groups of image lattice data corresponding to the one line of image lattice data to the internal buffer, writing the n groups of image lattice data in the corresponding internal buffer to an external storage; reading data from the external storage according to an arrangement rule of all nozzles. By cooperatively using the processor and the external storage, embodiments of the present invention reduce a processing cost of the image lattice data, and improve an image lattice processing speed. |
