Method for controlling asynchronous multi-nozzle collaborative printing

TL;DR: In this article, a method for controlling asynchronous multi-nozzle collaborative printing is described, where a host machine printing engine program generates printing data and control information and the data and the control information are transmitted to a printing main board controller.

Abstract: The invention discloses a method for controlling asynchronous multi-nozzle collaborative printing The method for controlling asynchronous multi-nozzle collaborative printing comprises steps that a host machine printing engine program generates printing data and control information and the printing data and the control information are transmitted to a printing main board controller; the printing data enters into a command parsing and data distributing module through a data channel of the printing main board controller; the command parsing and data distributing module distributes the printing data of nozzles to first level buffer FIFOs respectively; then the printing data is stored into an independent data area of an SDRAM after read-write arbitration through an internal storage controller; the printing data which is required to read through the internal storage controller is temporally stored in second level buffering FIFOs of the nozzles; finally the printing data is sent to the nozzle through driving modules of the nozzles
