DATA PROCESSING METHOD, APPARATUS AND INK-JET PRINTER

摘要

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

1. A data processing method, comprising:
Step S1: a processor sequentially receives multiple lines of image lattice data; after receiving one line of image lattice data, splits the one line of image lattice data to n groups of image lattice data according to a number of rows of nozzles corresponding to the one line of image lattice data along a paper feeding direction, wherein n is the number of rows of all nozzles; Step S2: after splitting the one line of image lattice data, the processor writes the corresponding split n groups of image lattice data to an internal buffer; Step S3: after writing the split n groups of image lattice data corresponding to the one line of image lattice data to the internal buffer, the processor writes the n groups of image lattice data in the corresponding internal buffer to an external storage; Step S4: the processor reads data from the external storage according to an arrangement of all nozzles and controls the nozzles according to the read data.
