  • Onepass system inkjet printing control method, device and storage medium
    Patent number: 11481589
    Abstract: A Onepass system inkjet printing control method, device and storage are provided. The method includes: dividing all physical channels into several groups according to a printing requirement command, defining one group as a printing module, wherein each of the printing modules includes x physical channels, x?1, x is an integer; configuring n logical channels for each printing module, wherein n?x, n is an integer; starting a printing command, and extracting corresponding printing data from the printing memory in units of the logical channel; processing the printing data according to the printing parameters and then inputting it into the corresponding physical channel for inkjet printing. The solution of the present invention ensures that each printing module can independently control the printing task during printing.
