[0002] Most of the ink cartridges and nozzles of the existing TIJ (Thermal Inkjet Technology) inkjet printers adopt an integrated design, and each ink cartridge is equipped with two parallel nozzle arrays, one of which is used as the working nozzle, and the other The nozzle array is used as a spare nozzle; since the printing speed of the inkjet printer is related to the printing frequency and printing resolution, and the printing frequency is determined by the characteristics of the ink cartridge and the circuit, the only way to increase the printing speed is to reduce the printing resolution. rate, which will make the printing effect poor, thus limiting the application field of TIJ inkjet printer

Embodiment Construction
[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0029] In related technologies, thermal foaming inkjet printers generally use a single set of nozzle arrays for inkjet printing, while TIJ inkjet printers need to use synchronization signals when they work, and control the nozzle array to spray once every time a synchronization signal is detected. , so the jetting frequency of the inkjet printer and the synchronization signal frequency are the same. Generally, the highest jetting frequency of the inkjet printer generally does not exceed 15Khz, which is determined by the character...

The present invention proposes an inkjet printer and a method and device for increasing the printing speed of the inkjet printer, wherein the method for increasing the printing speed includes: reading the printing data, and the printing data includes the first nozzle corresponding to the first nozzle array. print data and the second print data corresponding to the second nozzle array; read the first print data into the data buffer, and read the second print data into the temporary register for delay processing; When printing, detect the synchronization signal; read the first printing data as a frame of printing data according to the synchronization signal to control the first nozzle array to print, and when the delay time arrives, read the first printing data respectively The data and the second printing data are combined into one frame of printing data, so as to control the first nozzle array and the second nozzle array to simultaneously print. Therefore, the present invention achieves the purpose of increasing the printing speed by using two rows of nozzles together without reducing the printing resolution, thereby expanding the application field of the inkjet printer.
Description
technical field [0001] The invention relates to the technical field of inkjet printing, in particular to an inkjet printer, a method and a device for increasing the inkjet printing speed of the inkjet printer. Background technique [0002] Most of the ink cartridges and nozzles of the existing TIJ (Thermal Inkjet Technology) inkjet printers adopt an integrated design, and each ink cartridge is equipped with two parallel nozzle arrays, one of which is used as the working nozzle, and the other The nozzle array is used as a spare nozzle; since the printing speed of the inkjet printer is related to the printing frequency and printing resolution, and the printing frequency is determined by the characteristics of the ink cartridge and the circuit, the only way to increase the printing speed is to reduce the printing resolution. The rate will make the printing effect poor, thus limiting the application field of TIJ inkjet printer. Contents of the invention [0003] This applicat...
