HEAD DRIVING DEVICE, INKJET PRINTER COMPRISING THE SAME AND DATA PROCESSING METHOD THEREOF

摘要

A head driving device, an inkjet printer including the same, and a data processing method thereof are provided to improve EMI(ElectroMagnetic Interference) property among signals by lowering density of a data bus in the same area and adjust a data processing rate by dividing/processing printing data. A nozzle driving part(30) controls electric conduction of multiple heaters for heating ink by responding to multiple nozzles injecting the ink. A data processor(20) outputs a nozzle selection signal corresponding to an image to the nozzle driving part by processing the printing data. A head logic part(10) receives the printing data from the outside, divides the printing data of the same address group into the first and second group data, divides/transfers the first and second group data to the data processor through each data bus matched with each group, and makes the data processor divide/process the printing data. The data bus includes the first data bus for transferring the first group data and the second data bus for transferring the second group data.
