Abstract

The utility model discloses an inkjet printer electric table based on thee-optical-fiber communication, which is subjected to data and command exchange with a computer in a USB2.0 (universal serial bus 2.0) high-speed mode. When the inkjet printer electric table is used for printing, a main board receives and buffers printing data transmitted from the computer through a USB2.0 interface, a DSP (digital signal processor) receives grating decoded signals transmitted from a small trolley plate through a command optical fiber channel, and nozzle data loading and generation of ignition signals for a nozzle are determined according to the signals. When the DSP generates load signals for the nozzle, an FPGA (field programmable gate array) on the main board transmits the printing data in cache to the small trolley plate through a data optical fiber channel, and the data is received and loaded to the nozzle through the small trolley plate, and when the small trolley plate receives nozzle ignition signals through command optical fibers, a nozzle ignition driving circuit is controlled for ignition, and data loaded to the nozzle are printed.
