Data processing method and device for printing output equipment

Abstract

The invention discloses a data processing method and a data processing device for printing output equipment. The data processing method for the printing output equipment in the embodiment of the invention comprises the following steps of: receiving a file to be processed; acquiring the parameter of the file to be processed; allocating a memory which can be mutually shared for the process of the file to be processed according to the parameter of the file to be processed; and performing data processing on the file to be processed. By the embodiment of the invention, high-speed printing can be realized.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a data processing method and device for printing output equipment. Background technique [0002] At present, the entire process of high-speed digital printing output mainly includes: PDF generation process, RIP (Raster Image Processing, rasterized image processing) process and output process. Wherein, in the early PDF generation process related to printing, due to the output of more than one million variable data, the generated PDF file is very huge, so the temporary file storage and reading can only be carried out through the physical disk; During the RIP process, due to the variety of data formats and complex processing, a huge amount of intermediate data is generated, so in the traditional processing scheme, some intermediate data are usually used for physical disk buffering and reading; the dot matrix data generated after RIP is due to the data The amount is huge, generally...

Problems solved by technology

[0003] In this way, in the whole process of realizing the high-speed digital printing output, the inventor found the following problems in the prior art: in the way of using the physical disk for data storage and reading, due to the storage and reading of the physical disk Due to the limitation of speed, the actual data throughput rate of the output module of the high-speed printing system is not high. The data throughput requirement of the module has reached 336MByte / s, so it can be seen that the storage and reading speed of the physical disk limits the actual data throughput of the output module of the high-speed printing system

In the way of using the memory for data storage and reading, due to the limitations of many aspects of the operating system, for example: the memory addressing space can support a maximum of 4GByte, the memory space directly allowed to apply for a single process can only reach 50% of this value % or so, so that the available memory of a single process is limited
