As an example of the analysis of the resource data by the host computer 100, for example, the printer 150
The time data required for rasterizing an outline font having a predetermined size of 0 is stored in advance as table data. If the size of the outline font of the recorded data matches the stored size, the table data is stored. Is to determine the rasterization processing load on the host computer 100 and the printer 1500 by correcting the outline font table data of the recording data and integrating the rasterization processing time of each character.

Further, when calculating the rasterization processing time, if the number of interpolation points for interpolating each point (for example, interpolation using a Bezier curve) is taken into account, a more accurate processing time can be calculated.

Further, when calculating the rasterization processing time, when the printer 1500 has a plurality of languages that can be processed or when the recording processing can be performed at a plurality of resolutions, a plurality of tables for calculating the rasterization processing time are provided.

According to the above embodiment, the host computer obtains the resource data of the printer, analyzes the print job based on the resource data, and determines the ratio of the rasterization processing load of the printer and the host computer to the rasterization information of the print job. Since the rasterization information extracted from the print job according to the determined rasterization processing load ratio is configured to be rasterized by the host computer and / or the printer in parallel, the rasterization information processing between the printer and the host computer is performed. The burden can be equalized.

Further, since the rasterizing information including the font data and the vector graphics data is divided and processed in parallel, the print job can be efficiently processed while equalizing the data processing load between the printer and the host computer. Can be.

Further, in the printer control system according to the embodiment of the present invention, the host computer acquires the resource data of the printer, and when the print job occurs,
The print job is analyzed based on the resource data of the printer to dynamically determine the parallel processing sharing ratio between the first rasterizer and the second rasterizer, and the second rasterizer or the second rasterizer is determined according to the determined parallel processing sharing ratio. Since the first rasterizer is configured to process the rasterized information in the print job in parallel, the print job can be efficiently processed while equalizing the data processing load on the printer and the host computer.

Furthermore, since rasterization information including font data and vector graphics data is shared and processed in parallel, a print job can be efficiently processed while equalizing the data processing load on the printer and the host computer. It is possible to easily construct a system capable of performing the above.

The determining means is configured to analyze the font size in the print job based on the resource data of the printer and to dynamically determine the parallel processing sharing ratio between the first rasterizer and the second rasterizer. Therefore, the rasterizing process corresponding to the font type can be shared between the host computer and the printer.

Further, the determination means analyzes the amount of outline interpolation information in the print job based on the resource data of the printer, and dynamically determines the parallel processing share ratio between the first rasterizer and the second rasterizer. Therefore, the rasterizing process corresponding to the number of interpolations in the outline information can be shared between the host computer and the printer.
