Abstract
An apparatus and a method for multichannel sequence transmission and control comprises a DMA generator, a bus interface, a data generator, a control unit, and a strobe signal generator. The DMA generator is coupled to the bus interface and the data generator to operate with the control unit and the strobe signal generator. A step of initial setting is an external microcontroller generates a TPH shift clock and a TPH latch signal needed by a print head. A step of transmitting data is the DMA generator transmits a printing data to the data generator for being buffered and moved to a latch register in the print head and then the strobe signal generator provides the signal period of the respective strobe signal and the time spacing between the respective strobe signal to allow a multiplexer outputting the actual strobe signals, which are combined from the virtual strobe signals, to the print head. A step of heating the print head is the print head prints the assigned data until the strobe signals ending.
