It is determined whether or not it is (step S211). If it is determined that N = 1, the process proceeds to step S310. If it is determined that N is not 1, the process proceeds to step S212.

If N = 1 is not satisfied, the control unit 11 creates an object list, for example, as shown in FIG.

age Description Language, page description language), a PDL flag indicating whether or not the object can be converted, a duplication number indicating the presence or absence of duplication of the object, and a group thereof. Next, the control unit 11 sets ON the PDL flag of the object number 1 in the object list as an initial value (step S213).

First, for example, Obj-A and Obj-A shown in FIG.
Analysis is performed on B. The control unit 11 sets 1 as an initial value of n indicating an object number to be analyzed, and sets 0 as an initial value of k indicating a duplicate number (step S21).
4). k = 0 means that there is no overlapping object. The control unit 11 determines whether or not N = n (step S215). If it is determined that N = n, the control unit 11 proceeds to step S31.
0, and when it is determined that N = n is not satisfied, step S is executed.

Since k = 10 and n = 1, the control unit 11 determines that N = n and determines the number of the object whose duplication is to be analyzed with the n-th object (hereinafter abbreviated as object n). M = m as the initial value
n + 1 is set (step S216). This allows
m = 2 is set. Hereinafter, the m-th object is referred to as an object m.

The control unit 11 analyzes the overlap of the object n and the object m with the spooled print data (step S217), and determines whether or not the print data overlaps (step S218). In this case, since the objects Obj-A and Obj-B are in the state as shown in FIG.
(Obj-A: n = 1) and object m (Obj-B: m =

The control unit 11 sets the object n (Obj-A:
Based on the determination that n = 1) and the object m (Obj-C: m = 3) do not overlap, ON is set in the column of the PDL flag of the object m in the object list (step S229). This means that the object m (Obj-C) is converted to PDL and output.

After the processing in step S229, the control unit 11 determines whether N = m (step S226).
m (N = 10, m = 3), it is determined that m =
m + 1 (4 = 3 + 1) is set (step S230),

OFF is set in the flag column (step S225).
This means that the object m is processed in the host 10 in association with the object n instead of being converted to PDL and output.

After the processing in step S225, the control unit 11 determines whether N = m (step S226).
m (N = 10, m = 4), it is determined that m =
m + 1 (5 = 4 + 1) is set (step S230),

As described above, according to the first embodiment, it is determined whether or not an object and another object overlap with the spooled print data. Is determined to be necessary, and the PDL flag indicating whether or not the object can be converted into the page description language is turned off. If there is no overlap, it is determined that the logical rendering process in the host 10 is not necessary. At the same time, the PDL flag is set to ON. If the PDL flag is OFF, the object data is converted into an image format of a page description language by performing rasterization processing in consideration of logical drawing, and if the PDL flag is ON, the object data is converted to a page. The printer 20 converts the description data into descriptive language data and transfers the converted data to the printer 20 for printing.

(2) Second Embodiment As a second embodiment, a logical rendering process is performed based on information of a plurality of objects described in the first embodiment, and all objects are rasterized. Step S
It is possible to improve 316.

In the first embodiment, as shown in FIG. 9, a rectangular area encompassing all objects requiring a logical drawing process is targeted. In this case, efficiency is insufficient because the processing is also performed on a part that does not need to perform the logical drawing processing and the rasterization processing.

Therefore, in the second embodiment, all objects requiring a logical drawing process are converted to PDL data. On the other hand, a rectangular area where objects overlap each other and logical drawing processing is required is extracted. Only the extracted area is subjected to logical drawing processing and rasterizing processing to create bitmap data. Then, after transferring the PDL data of the overlapping object to the printer 20, the bitmap data is transferred to the printer 20 and printed.

For example, if the processing is performed as shown in FIG. 9, after transferring the PDL data of Obj-A, Obj-B, Obj-D, and Obj-F to the printer 20, two PDL data as shown in FIG. The bitmap data is transferred to the printer 20. Also,

After the PDL data is transferred to the printer 20, the bitmap data as shown in FIG.

As described above, according to the second embodiment, all objects requiring logical drawing processing are
On the other hand, while converting the data into data, the object and the object are overlapped to extract a rectangular area that requires the logical drawing processing, and only the extracted area is subjected to the logical drawing processing and the rasterizing processing to create the bitmap data and to be overlapped. After the PDL data of the object is transferred to the printer 20, the bitmap data is transferred to the printer 20 for printing. Therefore, the data amount can be further reduced, and the data transfer speed and the processing speed can be increased.

(3) Third Embodiment As a third embodiment, improvement may be made by adding a new step after the creation of the object list described in the first embodiment.

In the first embodiment, after the processing from step S210 in FIG. 2 to step S230 in FIG. 3 is repeated to analyze all the objects and create an object list, the objects whose PDL flag is ON are converted into PDL. The object whose PDL flag is OFF has been output by subjecting a plurality of objects to bitmap processing (including logical drawing processing). In this case, the object to be converted to the PDL and the object to be converted to the bitmap are in a mixed form, and the mixed processing form may lower the conversion efficiency in the host 10 and the processing efficiency in the printer 20.

Therefore, in the third embodiment, before step S310 in FIG. 4, a step is provided for comparing the case where the processing forms are mixed and the case where all of the processing forms are converted into bitmaps. If it is determined in this step that conversion to all bitmaps is more efficient, objects with the PDL flag ON in the object list are simply converted to bitmaps, and objects with the PDL flag OFF are logical. Convert to bitmap considering drawing. When converting an object whose PDL flag is ON to a bitmap, it analyzes whether it is more efficient to perform bitmap conversion by combining objects whose other PDL flags are ON.

As described above, according to the third embodiment, if it is determined that the conversion to all bitmaps is more efficient, the PD in the object list is used.
When the object whose L flag is ON is simply converted into a bitmap, the object whose PDL flag is OFF is converted into a bitmap in consideration of logical drawing, and when the object whose PDL flag is ON is converted into a bitmap, Since it is analyzed whether it is more efficient to perform bitmap conversion by combining objects with other PDL flags ON, the printing process in the printer 20 can be made more efficient.

(4) Fourth Embodiment As a fourth embodiment, improvement may be made by adding a new step after the creation of the object list described in the first embodiment.

In the first embodiment, it is assumed that output is made to a printer that cannot perform logical drawing processing.

Therefore, in the fourth embodiment, for example, the host 10 shown in FIG. 1 is connected to a network, and can be output to a printer other than the printer 20. In this configuration, when the object list is analyzed, it is determined whether or not there is a logical drawing process on the print data. If logical drawing processing is necessary, information of another printer on the network is acquired, and a printer capable of logical drawing processing is searched. If a printer capable of logical drawing processing is found, all PDL flags in the object list are changed to ON, and the subsequent processing is performed. Then, only the generated PDL data is output to a printer capable of performing a logical drawing process.

As described above, according to the fourth embodiment, when the object list is analyzed, it is determined whether or not there is a logical drawing process on the print data. Information on other printers is obtained, a printer capable of logical drawing processing is searched, and if a printer capable of logical drawing processing is found, all PDL flags in the object list are changed to ON, and subsequent processing is performed. Since only the generated PDL data is output to a printer capable of performing a logical drawing process, it is possible to automatically select an optimal print processing mode, and it is possible to perform print processing in the printer 20 at high speed and efficiently.
