Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to control of a data processing device that converts print data from an application into data that can be printed by a printing device.
[0002]
[Prior art]
In a printing system including a conventional data processing device and a printing device, when printing is performed based on a specification from an application or the like, PDL print data that can be processed by a printing device at an output destination is generated on a host device, and the printing device generates the PDL print data. By transmitting, desired print processing is performed.
[0003]
In recent years, improvements have been made to the PDL data format between a host device and a printing device in order to speed up printing time for printing data that is becoming more complicated and to reduce the cost of the printing device. In particular, by dividing the PDL data into bands, the time required for one processing is reduced, and the processing is optimally distributed as a whole printing system.
[0004]
At this time, the printing apparatus secures a memory for holding data input from the host apparatus as internal intermediate data and an image buffer for each band data corresponding to the band size, and sequentially performs drawing processing in the buffer. .
[0005]
In order to minimize the memory size while increasing the speed, the image buffer is used to output color components, usually YMCK, and the number of bits per color pixel, usually 1 or 2 or 4 bits. , The image buffer is reserved.
[0006]
In the host device, the print data from the application is converted into a print code obtained by dividing the print device into bands, and each band data is converted into an 8-bit gradation of RGB or a gradation matching the output gradation of the YMCK printing device. The print data was sequentially transmitted to the printing device.
[0007]
[Problems to be solved by the invention]
In the above conventional example, if the page is relatively simple, data processing can be performed by the controller unit in the printer in time for the printing speed of the printer. However, the controller processing for the band has become a bottleneck, leading to a reduction in printing time.
[0008]
Further, in a band where a large amount of drawing is performed, the internal intermediate data for one band cannot be held due to the limitation of the memory mounted on the printer, and complicated internal error processing is performed. In some cases.
[0009]
Also, if there is data in a certain band that requires logical operation processing such as combining processing and drawing with a base, it is converted to YMCK in the image buffer, or converted to an image with the gradation dropped according to the printing device. Therefore, the logical operation cannot be performed accurately.
[0010]
For this reason, processing that takes a long time, such as restoring the RGB high gradation from the YMCK low gradation data, performing logical operation processing in that state, and returning to the YMCK low gradation again, has been performed.
[0011]
Also, in the process of restoring to RGB, since a color conversion process from device YMCK to RGB and a conversion process from a state where the number of gradation bits is reduced to a full color gradation are required, complete restoration is impossible. In addition, there is a problem that a result of logical operation in RGB cannot be obtained with good quality.
[0012]
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to analyze each page of print data from an application for each of a plurality of predetermined band-shaped areas. According to the analysis result, when the print code for drawing the area is divided for each of the first area and the second area by dividing the area into further strip-shaped areas. Adding, to the generated print code, segmentation information indicating that the segmentation has been performed, and transmitting the print code generated by adding the segmentation information to a printing apparatus, thereby allowing any one of the pages to be printed. Even if the print data is generated so that the logical operation drawing output overlaps in a complicated manner on the belt-like area, the necessary resources can be adapted to the existing system resources without expanding the system resources on the printing device side. Strip Because frequency can drawing process as strip-like regions which are further subdivided to provide a data processing apparatus which makes it possible to perform high-quality logic operation draw output without compromising performance in any printing device.
[0013]
[Means for Solving the Problems]
The data processing device of the present invention that achieves the above object has the following configuration.
[0014]

[0032]
Here, an example is shown in which the basic band is further divided into four subbands.
As is apparent from this example, the band that was complicated in (B) is subdivided, so that the data amount of the band is reduced.
[0033]
Further, by making the band size smaller than the bandwidth shown in (B) as shown in (C), the band buffer memory can be allocated as the internal intermediate data storage area.
[0034]
FIG. 3 is a flowchart showing an example of a first data processing procedure in the printing system according to the present invention, and corresponds to the data processing procedure of the host device 1 shown in FIG. S301 to S315 indicate each step.
[0035]
First, when the printing process in the host device 1, which is a data processing device, is started, in step S301, the host device 1 is initialized, and the printing capability information of the printing device 11 is obtained from the printing device 11, Preparations for printing processing by the printing apparatus 11 are made.
[0036]
Further, with respect to the printing apparatus to be output, the band size information held in advance is extracted, and the basic band size is determined. Alternatively, information relating to the basic band size is received from the printing apparatus, and the basic band size is determined.
[0037]
Next, in step S302, it is determined whether or not print data is input from the application. If the print data is input, in step S303, the data analysis unit 5 analyzes the print data based on the print data from the application. The processing is performed to check which part of the page is to be subjected to logical drawing and which part of the page is to be subjected to complicated printing processing.
[0038]
It should be noted that complicated print processing is determined based on whether the number of print elements exceeds the number assumed in advance.
[0039]
Next, in step S304, it is determined whether or not the page is completed. If it is determined that the page is not completed, the process returns to step S302. If it is determined that the page is completed, in step S305, the band division processing unit 6 Divides the print data into basic bands. Next, in step S306, it is determined whether or not the band needs to be re-divided based on the analysis result of the data analysis unit 5.
[0040]
It is assumed that the processing from step S306 to step S313 is sequentially performed on all bands of the page currently being processed. If it is determined in step S306 that re-division is not necessary, the print code generation unit 8 performs band data generation processing in accordance with the basic band size in step S307, and proceeds to step S313.
[0041]
In step S307, the color / tone conversion unit 7 converts the color space input from the application into YMCK or YMC according to the printing apparatus 11, and performs conversion in accordance with the output tone number of the printing apparatus 11. Do.
[0042]
On the other hand, if it is determined in step S306 that re-division is necessary, the band division processing unit 6 determines the number of re-divisions in step S308.
[0043]
When re-division is performed for logical drawing reasons, the band size in RGB full color is calculated so as to be within the band buffer memory size determined from the output gradation of YMCK or YMC and the basic band size.
[0044]
For example, if YMCK output is 2 bits per pixel and the basic band height is 768 pixels, the band height after re-division is 256 pixels for RGB 24 bits, which is further divided into three.
[0045]
In the case of subdivision due to the complexity of the band, a predetermined optimal subdivision number is used. The example shown in FIG. 2C as an example of the present embodiment is an example in which the optimal division number is “4”.
[0046]
Next, in step S309, the band division processing unit 6 performs re-division processing of the basic band. Specifically, the band division processing unit 6 performs the division processing of the basic band according to the division number determined in step S308.
[0047]
Next, in step S310, the print code generation unit 8 performs band data generation processing according to the band size at the time of re-division. It is assumed that the processes from step S310 to step S311 are sequentially performed on all the subdivided bands in the basic band currently being processed.
[0048]
Further, in step S310, if the image is re-divided for the reason of the logical drawing, the color / tone conversion unit 7 converts the color space input from the application into RGB 24-bit gradations, which is because the data is complicated. For example, the color / tone conversion unit 7 simply converts the color space input from the application into YMCK or YMC according to the printing device according to the re-determined band size, and matches the output device with the number of output gradations of the printing device. Perform the conversion.
[0049]
Next, in step S311, it is determined whether or not the final band at the time of re-division has been processed. If the final band has not been processed, the process returns to step S310. If the final band has been processed, the process returns to step S312. The print code generation unit 8 adds information indicating that the band has been subdivided into band data, the band size at the time of subdivision, color space information, the number of gradations, and the like. In step S313, the basic band currently being processed is added. , It is determined whether it is the last band of the page. If the determination is NO, the process returns to step S306. If the determination is YES, in step S314, the data transmission / reception unit 10 transmits data to the printing device 11, and returns to step S302.
[0050]
On the other hand, if it is determined in step S302 that the input from the application is another process designation, a process according to the designation is performed in step S315, and the process returns to step S302. The above is the operation of the printing process in the host device 1 in the present embodiment.
[0051]
Next, processing of the printing apparatus 11 in the printing system will be described with reference to FIG.
[0052]
FIG. 4 is a flowchart showing an example of the second data processing procedure in the printing system according to the present invention, and corresponds to the data processing procedure of the printing apparatus 11 shown in FIG. S401 to S405 indicate each step.
[0053]
First, when the printing process in the printing device 11 is started, the printing device 11 is initialized in step S401 to prepare for the printing process. Then, in step S402, the print code data is received from the host device by the data transmitting / receiving unit 12, and in step S403, the information code is processed by the print code data processing unit 14, and the print code can be imaged and printed in step S404. Then, in step S405, a printing process is performed by the output unit 16, and the process returns to step S402. The above is the operation of the printing process in the printing apparatus 11 according to the present embodiment.
