Abstract

The invention relates to an ink-jet print controller, which is connected to a processor and a storage device via a bus, wherein, the storage device is used to store the printed image data; the ink-jet print controller is used to extract printed image data stored in said storage device to be calculated to drive one or several ink-jet heads. The ink-jet controller comprises a direct-storing controller, an instruction internal memory, and an extraction processor. The instruction internal memory can extract the extraction instruction of printed image data; the extracting processor is connected to the instruction internal memory and the direct-storing controller to calculate the address of said storage device stored in the direct-storing controller according to the extracting instruction of instruction internal memory; and the direct-storing control can store the printed image data of storage device according to said storing address.

Description

technical field [0001] The invention relates to an inkjet printing control device, in particular to an inkjet printing control device which uses simple instructions to read scattered printing data. Background technique [0002] Due to the rapid popularization of multimedia, inkjet printers that can provide color printing have also entered many families. Since the inkjet printer can print multiple lines at a time, and with the mechanical characteristics of the nozzle arrangement of the inkjet print head or other hardware characteristics, the printed image data is not captured line by line from top to bottom, but usually some Regular or irregular line skipping, which needs to be sorted by the processor on the inkjet printer or the personal computer connected to the inkjet printer, which will occupy the processor time and bus bandwidth of the inkjet printer or personal computer. [0003] As shown in FIG. 1 , the general arrangement of image data in the memory is stored sequent...
