Printing data processing method and system

Abstract

The invention relates to the technical field of printing, and provides a printing data processing method and system. The method comprises the following steps: applying for a buffer area between every two processing threads, controlling the first processing thread to carry out color processing on a printing data file, storing the processed printing data into a storage unit of the first buffer area through an inlet pointer of the first buffer area, controlling the second processing thread to read the printing data in the storage unit through an outlet pointer of the first buffer area, and meanwhile, controlling the second processing thread to perform the same processing operation as the first processing thread on the read printing data until the (N+1)th processing thread, wherein the (N+1)th processing thread carries out color data processing on the printing data and outputs the processed printing data. The running thread processing mode solves the problem of non-synchronization due to different processing speeds of parallel threads, accelerates the printing data processing speed, and is also suitable for transmission of mass multipage data.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a printing data processing method and system. Background technique [0002] At present, color printing data processing generally adopts a single-thread or multi-thread parallel processing method. The single-thread processing method is relatively simple, which is to process the printing color data according to the set order; while multi-threading is to process each color data of the same page at the same time. After each page is processed, a thread synchronization is required, that is, after each thread has processed the data, after the thread synchronization operation is performed, the printing data of this page is output, and then each parallel thread starts processing at the same time One page of printed data such as figure 1 Shown: [0003] Assuming that there are three types of printing color data on the current page, three processing threads are required to pr...

Problems solved by technology

[0005] The purpose of the embodiments of the present invention is to provide a printing data processing method, aiming at solving the problem that the printing data processing method provided by the prior art is single-threaded or multi-threaded parallel processing. The difference in speed leads to the phenomenon that the processing of printing data is not synchronized, that is, the thread that has completed processing needs to wait for the thread that has not completed processing, and the printing data of the current page will not be output until the multiple parallel threads are processed, and the synchronization is completed. As a result, it affects the overall transmission speed of printing data and becomes the bottleneck of printing data transmission.
