In this example, it is assumed that the print data is hyperlink data. In addition, (301)-(314) shows each step.
[0052]
First, a print request is made from the host computer 201 to the printer driver 202 (S301). Next, the printer driver 202 downloads the entire print range excluding the image data of the data requested to be printed (S302). Then, the data is analyzed to extract a link to the image data (S303).
[0053]
Next, a link to the same address is searched, and the number of links is counted for each image (S304).
[0054]
Then, information indicating that it is linked a plurality of times is added to the print data for each corresponding image data (S305), and the print data to which the information indicating that it is linked is added is transferred to the printing apparatus 203. (S306).
[0055]
Next, in the transfer of image data, it is checked whether it has already been transferred (S307). If it is determined that it has already been transferred, the process proceeds to step 310, and if it is determined that the image has not been transferred yet. In step S308, the image transmission check is performed, and then the image is transmitted to the printing apparatus 203 (S309).
[0056]
On the other hand, the printing apparatus receives the data transmitted from the printer driver 202 (S310). That is, when the image data has been transferred, the controller unit 206 determines whether the image data is image data linked a plurality of times based on information added to the print data (S311). If it is determined that the image data is not linked, the process proceeds to step (313). If it is determined that the image data is an image linked a plurality of times, the image data is stored on the RAM in the controller unit 206. (S312).

First, a print request is made from the host computer 201 to the printer driver 202 (S401). Next, the printer driver 202 downloads the entire print range excluding the image data of the data requested to be printed (S402). Next, the data is analyzed to extract a link to the image data (S403). Then, a link to the same address is searched, and the number of links is counted for each image data (S404).
[0060]
Next, information indicating that the image is linked a plurality of times is added to the print data for each corresponding image (S405). Next, the printer driver 202 transfers the print data to the printing apparatus 203 (S406).
[0061]
Then, in the transfer of image data, it is checked whether it has been transferred (S407). If it is determined that it has already been transferred, the process proceeds to step (410), where the printer driver 202 uses an untransferred image. If it is determined that there is an image, a transmission completion check of the image is performed (S408), and after the check, image data is transmitted to the printing apparatus 203 (S409).
[0062]
On the other hand, when the printing apparatus receives the data transmitted from the printer driver 202 (S410), that is, when the image data is transferred, the image is linked multiple times based on the information added to the print data. If the controller unit 206 determines that the image is not linked to multiple times (S411), the controller unit 206 proceeds to step (413), and if it is determined that the image is linked multiple times, The image data is cached in a cache area (memory area) secured on the RAM of the controller unit 206 (S412).
[0063]
Then, the printing apparatus 203 develops an image on a page buffer that secures print data on the RAM in the controller unit 206 (S413). Next, it is determined whether the memory area for caching the image data has run out of capacity, that is, whether the memory is full (S414). If it is determined that the memory is not full, the process proceeds to step (416). If it is determined that the memory is full, the cached image data is deleted from the cache memory area (S415).

It goes without saying that a case where the function of the above-described embodiment is realized by performing part or all of the actual processing and the processing is included.
[0122]
Further, after the program code read from the storage medium is written to a memory provided in a function expansion board inserted into the computer or a function expansion unit connected to the computer, the function expansion is performed based on the instruction of the program code. It goes without saying that the case where the CPU or the like provided in the board or the function expansion unit performs part or all of the actual processing and the functions of the above-described embodiments are realized by the processing.
[0123]
【The invention's effect】
As described above, according to the present invention, the number of transfers of the same image data to be transferred from the information processing device side to the image processing device side can be reduced, and an output result including the intended image data can be obtained in a short time. Can do.
[0124]
In addition, the number of times of transfer of the same image data to be transferred from the information processing apparatus side to the image processing apparatus side can be reduced, and an output result including intended image data can be obtained in a short time.
[0125]
In addition, a convenient image processing system environment that can efficiently process output data based on the hyperlink format by effectively utilizing the limited memory on the image processing device without caching the image data There are effects such as being able to construct freely.
