TECHNICAL FIELD OF THE INVENTION
The present invention relates to a document processing method and apparatus for printing out a created document.
[0002]
[Prior art]
2. Description of the Related Art In a conventional document processing apparatus, a method of executing document editing by using font data in the document processing apparatus and executing printing of a document by using font data in a printer during printing may be used. By using such a method, the transfer efficiency of data from the document processing apparatus to the printer at the time of printing is improved, and the advantage that the best output is obtained with font data having a resolution suitable for each printer is obtained.
[0003]
On the other hand, a document processing apparatus for creating a high-quality document has been requesting an enormous amount of font data, and the font data provided in a printer has become unable to cope with it. As a countermeasure, if there is a request to print with a font that the printer does not have, print using a font that is similar to the requested font among the fonts that the printer has as a substitute font. I have.
[0004]
[Problems to be solved by the invention]
By the way, when creating a high-quality document, a proportional font is often used to balance the size of characters. In this proportional font, each character has a different character width even with the same font and size. Such a proportional font is generally used particularly for European characters and the like, but is also being used for Japanese character fonts.
[0005]
When performing printing using the above-described proportional font, if another font provided in the printer is used, characters are developed with the character width of the substitute font. For this reason, the number of lines and the number of pages of the entire document may change, and the appearance of the entire document may change. Further, in order to maintain the appearance of the entire document, image data may be generated on the document processing apparatus side and transferred to the printer side, but a great deal of time is required for data transfer.
[0006]
Further, as described above, when the corresponding font is provided in the printer, the transfer efficiency is improved by executing the expansion of the font data on the printer side, and the time required for the printing process is shortened. However, since the processing speed of the printer is generally slower than that of the document processing device, if the font data to be processed is enormous, if the font data is expanded on the printer side, it takes much time for the processing. Become. In such a case, it is advantageous in terms of processing time to develop the font image on the document processing apparatus side and transfer the bitmap data to the printer.
[0007]
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is possible to appropriately select whether to execute expansion of a font image on a document processing apparatus side or on a printer side, and to efficiently execute printing.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0013]
<First embodiment>
FIG. 1 is a block diagram illustrating a schematic configuration of the document processing apparatus according to the present embodiment. Reference numeral 1 denotes a main controller (CPU), which controls the entire document processing apparatus. Reference numeral 2 denotes a ROM (Read Only Memory), which stores various control programs executed by the CPU 1. The ROM 2 stores, for example, a document editing program including communication with a printer shown in FIGS. 2, 5, and 7 described below. Reference numeral 3 denotes a RAM (Random Access Memory), which temporarily stores various data and file data obtained via the system bus 4.
[0014]
Reference numeral 4 denotes a system bus, which is connected to each unit in the document processing apparatus so that data can be exchanged between the units. A printer interface 5 connects the printer 6 to the document processing apparatus. A printer 6 forms an image based on print data input via the printer interface 5 and executes printing on a recording medium. Here, the CPU 1 can communicate with the printer 6 via the printer interface 5 connected by the system bus 4, and exchanges data with the printer 6, creates documents, and prints according to the algorithms shown in FIGS. Perform processing. A disk interface 7 connects an external storage device such as a hard disk and the system bus 4. Reference numeral 8 denotes a hard disk connected by the disk interface 7, which stores a large amount of various file data such as document data and font data. Although the hard disk 8 is connected as an external storage device in this example, a floppy (registered trademark) disk or the like may be used.
[0015]
Next, the editing and printing processes of the document processing apparatus configured as described above will be described with reference to the flowcharts of FIGS.
[0016]
When the document processing device creates a document to be output using the printer 6, the document processing device classifies font data specified at the time of editing according to the flowchart of FIG. Here, the classification of the font data means that the font data provided in the document processing apparatus is classified into font data provided in the printer 6 and non-font data provided in the printer 6.
[0017]
FIG. 2 is a flowchart showing a procedure for classifying font data. In step S10, the font name and the point size (referred to as the main body font) of the font data existing in the hard disk 8 are read, and a main body font list is created. FIG. 3 is a diagram showing a data configuration of the font list 31 in the main body. As shown in FIG. 3, a font name 31a and a point size 31b are registered in the in-body font list. Further, ownership information 31c indicating whether or not the corresponding font exists in the connected printer 6 is registered. The registration of the possession information 31c is executed in step S15 described later.
[0018]
Next, in step S11, connection processing with the printer 6 is performed via the printer interface 5, and connection is confirmed in step S12. When the connection state is confirmed, the process proceeds to step S13, where the font name and the point size of the font data existing in the printer 6 are read, and a font list in the printer is created. FIG. 4 is a diagram showing the data configuration of the font list 41 in the printer. As shown in FIG. 4, a font name 41a and a point size 41b are registered in the font list 41 in the printer.
[0019]
In step S14, one font name and one size are read from the in-body font list 31, and it is determined whether or not the font name and size also exist in the in-printer font list 41. If the font and the point size are present in the font list in the printer, the font and the point size are marked in step S15. That is, information (“旨” in FIG. 3) indicating that fact is registered in the column of the proprietary information 31c of the in-body font list 31. In step S16, it is determined whether the classification has been completed for all of the font lists in the main body. If there is an unprocessed font, the process returns to step S14. In this way, the processes of steps S14 and S15 are performed until all the fonts in the in-body font list are classified.
[0020]
Next, a description will be given of the designation of the font type / size and the character width priority when editing a document in the document processing apparatus of the first embodiment. FIG. 5 shows a procedure for specifying a font when editing a document in the document processing apparatus according to the present embodiment. The user specifies the font / size for each character being edited by this processing. At this time, when a typeface that does not exist in the printer is specified, another font in the printer is used as a substitute font and printed. Further, when the substitute font is used, it is set whether or not the character width priority mode is set at the time of printout. Here, in the character width priority mode, the character arrangement information is preserved even if an alternative font is used by transferring the character width information when expanded with the font provided in the document processing apparatus main body to the printer side. It keeps the appearance. If the mode is not the character width priority mode, expansion to image data is performed using the character width of the substitute font (hereinafter, referred to as character quality priority mode).
[0021]
In step S20, a character or a character string to be set is specified in order to set a font and a point size for the character or the character string of the document being edited. Next, in step S21, the font and size of the character or character string specified in step S20 are set. As an example of this setting method, in the first embodiment, a font setting list as shown in FIG. 4 is displayed, and a desired font and point size are selected from this list. Note that the font setting list in FIG. 6 is generated from the above-described font list in the main body and the font list in the printer. In the font setting list, fonts existing in the printer are marked with “」 ”.
[0022]
Next, in step S22, it is determined whether or not the font specified in step S21 exists in the printer. If a font that does not exist in the printer is specified, the process proceeds to step S23, where the operator determines whether the character or character string in which the font is set is output in the character width priority mode or the character quality priority mode. Specify. In step S24, it is determined whether or not the font designation has been completed. If not, the process returns to step S20 to repeat the above-described processing. If the font designation has been completed, this processing is terminated.
[0023]
A procedure for printing a document in which a font and an output mode are designated as described above will be described with reference to FIG. FIG. 7 is a flowchart illustrating a procedure of a printing process of the document processing apparatus according to the first embodiment.
[0024]
In step S30, it is determined whether the font set for the character to be printed is a font existing in the printer 6 (referred to as a font in the printer). If the font is within the printer, the process proceeds to step S31, where data for designating the font and point size (designation data for the font type) and the character code are transmitted to the printer 6. The printer 6 develops the transferred character code into a dot pattern of the designated font and point size.
[0025]
On the other hand, if it is determined in step S30 that the font is not a printer font, the process proceeds to step S32, and a font (alternative font) to be used as a substitute is determined from the fonts of the printer 6. In the first embodiment, an alternative font correspondence table as shown in FIG. 8 is used as an example of a method for determining an alternative font. The substitute font correspondence table is created in advance by an operator.
[0026]
Next, in step S33, referring to the output mode (character width priority / character quality priority) specified in the previous step S23, it is determined whether the alternative font is output in the character width priority mode or the character quality priority mode. I do. In the character width priority mode, as described above, in order to maintain the character arrangement of the originally specified main body font, printing is performed by matching the character width of the specified main body font with the character width (character position) of the substitute font Is what you do. On the other hand, the character quality priority mode gives priority to the quality of each character and performs printing with the original character width of the substitute font in the printer. Therefore, in the character quality priority mode, the number of characters per line of the document may be different.
[0027]
If the character quality priority mode has been specified in step S33, the process proceeds to step S34, where data specifying the type of the substitute font and the character code are transmitted to the printer 6. The printer 6 develops the transferred character code into a dot pattern using the font designated as the substitute font. At this time, development into a dot pattern is executed according to the character width of the substitute font.
[0028]
On the other hand, if the character width priority mode is specified in step S33, the process proceeds to step S35. In step S35, when the character width of the font in the body designated originally is used, it is calculated how much dot size each character to be printed requires. Then, a dot position at which each character is arranged is obtained, and a position at which each character starts, that is, a character start position is calculated. Next, in step S36, the data for designating the type of the substitute font, the starting position of each character, and the character code are transmitted to the printer 6. The printer 6 develops and prints the dot pattern of the font at each designated position. This is repeated until it is determined in step S37 that the characters of the entire document have been completed.
[0029]
As described above, according to the present embodiment, even when a font that does not exist in the printer is set in a state where the character width priority output mode is specified, the character width (character arrangement) of the main body is retained. This makes it possible to ensure the appearance of the entire document.
[0030]
<Embodiment 2>
According to the document processing apparatus of the first embodiment, one of the output modes of the character width priority and the character quality priority is selected, but an output mode that guarantees both the character width and the character quality is provided. Can also be configured. The document processing apparatus according to the second embodiment described below has three output modes: a character width priority mode, a character quality priority mode, and a character width / character quality priority mode.
[0031]
The general hardware configuration of the document processing apparatus according to the second embodiment is the same as that of the first embodiment, and a description thereof will not be repeated. The procedure for classifying the font data and the procedure for specifying the font are the same as those in FIGS. 2 and 5 of the first embodiment, and therefore the description is omitted here. However, in setting the output mode in step S23 in FIG. 5, the character width / character quality priority mode is added to the character width priority mode and the character quality priority mode, and the output mode is selected and set from three types of output modes. .
[0032]
Next, a procedure of a printing process according to the second embodiment will be described. FIG. 9 is a flowchart illustrating a print processing procedure of the document processing apparatus according to the second embodiment. Here, steps S40, S41, and steps S45 to S50 in FIG. 9 are the same as steps S30, S31, and steps S32 to S37 in the first embodiment (FIG. 7), respectively, and a description thereof will be omitted.
[0033]
In step S40, if the character to be printed is not a printer font, the process proceeds to step S42. In step S42, it is determined whether or not the output mode specified in step S23 is the character width / character quality priority mode. If the character width / character quality priority mode is designated, the process proceeds to step S43, where the document processing apparatus develops the font data into an image, and transfers the obtained bitmap data to the printer 6. By performing such processing, the data transfer amount is increased, and the speed of the printing process is reduced, but the output quality of the characters and the appearance of the entire document are maintained.
[0034]
First, in step S43, the document processing device develops a character code to be printed using the font data in the main body into a dot pattern using the designated font. In step S44, the bitmap data obtained in step S43 is transmitted to the printer 6. The printer 6 prints out the bitmap data as it is.
[0035]
On the other hand, if the character width / character quality priority mode is not specified in step S42, the process proceeds to step S45, and the subsequent processing (the same processing as steps S32 to S37 of the first embodiment) is executed. As described above, when the output mode is the character width priority mode or the character quality priority mode, an appropriate font in the printer 6 is used as a substitute font so as not to lower the printing speed.
[0036]
As described above, according to the document processing apparatuses according to the first and second embodiments, for each character or character string in a document to be printed, the appearance is given priority (character width priority mode) or individual character arrangement is performed. It is possible to specify whether to give priority to the appearance (character quality priority mode), and it is possible to prevent the output quality from lowering even in a printer having a small number of fonts. Further, in the second embodiment, the document processing device develops the dot pattern as necessary, so that it is possible to flexibly respond to a user's request.
[0037]
<Embodiment 3>
Next, a document processing apparatus according to a third embodiment will be described. In the document processing apparatus of the third embodiment, in order to maintain both character quality and character width, when a font that does not exist in the printer is specified, the data is expanded into image data using the font data of the document processing apparatus. In such a document processing apparatus, in order to efficiently execute the expansion processing on the image data, the setting of whether the expansion processing of the font data is performed on the document processing apparatus side or on the printer side is automatically performed. Note that the schematic configuration of the document processing apparatus according to the third embodiment is the same as that of the first embodiment (FIG. 1), and a description thereof will not be repeated.
[0038]
FIG. 10 is a flowchart illustrating interface information collection processing and font data classification processing in the document processing apparatus according to the third embodiment. In step S60, the data transfer rate with the connected printer is read from the printer interface 5. In step S61, a threshold value is determined which determines whether the transfer of the dot image to the printer is acceptable if the transfer speed is higher.
[0039]
An example of a method for determining a threshold will be described. The threshold value can be determined based on the average data amount of one printing process, the speed of the image developing process by the main body of the document processing apparatus, and the speed of the image developing process by the printer. For example, in FIG. 11, reference numeral 110a denotes a relationship between the transfer speed and the print processing time when a predetermined amount of data is expanded on the main body side. Reference numeral 110b denotes a relationship between the transfer speed and the print processing time when a predetermined amount of data is expanded on the printer side. Then, the transfer speed at which the print processing time when the expansion processing is performed on the main body side is shorter than that when the expansion processing is performed on the printer side is determined as the threshold value. Note that the method of determining the threshold is not limited to the above-described method, and various modifications are possible, such as, for example, sequentially calculating according to the amount of data to be processed.
[0040]
In the following steps S62 to S68, a font list in the main body and a font list in the printer are created, and classification is performed based on whether each font in the font list in the main body is a font existing in the printer. These processes are the same as the processes in the flowchart of FIG. 2 of the first embodiment, and thus description thereof will be omitted.
[0041]
Next, a print processing procedure in the document processing apparatus according to the third embodiment will be described. In the document data to be printed, a font type is designated for each character. The font type specified here is the type and size of the font. FIG. 12 is a flowchart illustrating a procedure of a printing process of the document processing apparatus according to the third embodiment.
[0042]
First, in step S80, the transfer rate obtained in step S60 is compared with the threshold value determined in step S61. As a result of this comparison, if the transfer speed is smaller than the threshold value, it is more efficient to develop the font data into an image in the printer, so the process proceeds to step S81 to develop the font data in the printer. In step S81, it is determined whether or not the font type specified for the character to be printed exists in the printer, using the font list in the main body. If the font type exists in the printer 6, the process proceeds to step S83, where the font type designation data and the character code are transmitted to the printer 6. The printer 6 develops a character image corresponding to the specified character code using the font data of the specified font type.
[0043]
If the font of the character to be printed does not exist in the printer in step S81, the process proceeds to step S82. In step S82, it is determined whether the font data of the character has already been transferred to the printer. If it has already been transferred, the process proceeds to step S83 described above. If the font data has not been transferred to the printer in step S82, the process proceeds to step S84 to transfer (download) the font data of the character to the printer 6. Thereafter, the flow advances to step S85 to transmit the downloaded font type designation data and character code to the printer 6. The printer 6 develops a character image corresponding to the specified character code using the font data of the specified font type. The printer 6 stores the font data transferred in step S84, so that the font pattern of the character need not be downloaded to the printer 6 from the next time.
[0044]
On the other hand, if the transfer speed is higher than the threshold value, it is more efficient that the document processing device develops the image data, and the process proceeds from step S80 to step S86. In step S86, the document processing device executes a font pattern development process. Then, the generated bitmap data is transmitted to the printer 6.
[0045]
In step S88, it is determined whether or not the output process has been completed for all the characters. If not, the process returns to step S80 to repeat the above process. On the other hand, if the output processing has been completed for all the characters, this processing ends.
[0046]
As described above, according to the third embodiment, the threshold value is the transfer speed at which the processing time is reversed between the case where the image is developed by the printer and the case where the image is developed by the document processing device. . Then, it is determined whether the processing for developing the image data is performed on the document processing apparatus side or the printer side depending on whether or not the data transfer speed between the document processing apparatus and the printer is greater than the threshold value. Therefore, the processing time in the printing process is reduced, and the printing process can be performed efficiently.
[0047]
<Embodiment 4>
If the document processing device and the printer are connected by a parallel interface or the like and high-speed data transfer is possible, the transfer speed is not considered, and the data based on the processing capability of the document processing device and the data based on the processing capability of the printer , It may be configured to determine which of the font data expansion processing is to be performed. In a fourth embodiment, such a document processing apparatus will be described. The schematic configuration of the document processing apparatus according to the fourth embodiment is the same as that of the first embodiment, and a description thereof will not be repeated.
[0048]
FIG. 13 is a flowchart illustrating a main body performance value based on the processing capability of the document processing apparatus, a printer performance value calculation procedure based on the printer processing capability, and a font data classification procedure. Here, the processes shown in steps S102 to S104 and steps S107 to S110 represent the creation of the font list and the classification process of the font data, which are the same as those in FIG. 2 of the first embodiment. Is omitted.
[0049]
In step S100, the operation speed (CPU speed) and memory size of the CPU of the main body are checked, and the performance value of the main body is calculated from these values (step S101). As an example of the method of calculating the main body performance value in step S101,
MIPS value of CPU x (10,000,000 + memory byte size)
Is used. Here, 10,000,000 is an appropriate constant determined depending on how the CPU speed and the amount of memory affect the development of the font pattern.
[0050]
In step S105, the CPU speed and memory size of the printer are obtained from the connected printer 6. Then, in step S106, a printer performance value is calculated. As an example of a method for calculating a printer performance value,
MIPS value of CPU in printer x 2.0 x (10,000,000 + memory byte size in printer)
Is used. Here, 2.0 is an appropriate constant for giving priority to the printer performance value over the main body performance value.
[0051]
Based on the main body performance value and the printer performance value obtained as described above, it is determined whether the processing for expanding the font data to the image data is performed by the main body or the printer. That is, if the performance value of the main body is larger than the performance value of the printer, the document processing apparatus performs the processing for developing the image data and transfers the bitmap data to the printer. On the other hand, when the printer performance value is equal to or larger than the main body performance value, the printer performs a process of developing the image data.
[0052]
FIG. 14 is a flowchart illustrating a print processing procedure of the document processing apparatus according to the fourth embodiment. First, in step S120, the main body performance value and the printer performance value are compared. As a result, when the printer performance value is smaller than or equal to the main body performance value, it is more efficient to execute the image development on the printer side, and the process proceeds to step S121. The processes in steps S121 to S125 are the same as those in steps S81 to S85 (FIG. 13) described above, and a description thereof will not be repeated.
[0053]
On the other hand, as a result of the comparison in step S120, when the main body performance value is larger than the printer performance value, it is more efficient to develop the image in the document processing apparatus main body, and the process proceeds to step S126. The processing from step S126 to step S128 is the same as the processing from step S86 to step S88 described above, and the description is omitted here.
[0054]
As described above, according to the fourth embodiment, when data transfer between the document processing apparatus and the printer is performed at high speed, the main body performance value based on the processing capacity of the document processing apparatus and the processing capacity of the printer Based on the printer performance value based on the selected device, a device for performing an image development process is selected. Therefore, the device is selected so that the time required for the printing process is reduced, and the printing process can be performed efficiently.
[0055]
<Embodiment 5>
The document processing apparatus according to the fifth embodiment calculates the size (bitmap size) of bitmap data to be expanded, and executes the processing to expand the image data based on the bitmap size and the transfer speed (document processing). Device or printer).
[0056]
FIG. 15 is a flowchart illustrating a procedure of a printing process in the document processing apparatus according to the fifth embodiment. In step S140, a bitmap size when the font data to be output is expanded in the main body is calculated. Then, in a step S141, it is determined whether or not the time for transferring this bitmap is larger than a certain threshold. The time to transfer the bitmap is obtained by (threshold / transfer speed). Here, the threshold is obtained, for example, as shown in FIG. FIG. 16 is a diagram illustrating a relationship between a transfer time and a print processing time when a predetermined amount of data is printed. In the figure, if the transfer time is smaller than a certain threshold value, it can be understood that the time required for the print processing is shorter when the processing is performed on the main body side. This threshold is used as the threshold used in step S141.
[0057]
Therefore, when the transfer time of the bitmap data is longer than a certain threshold, it is more advantageous to execute the rasterization to the image on the printer side in terms of the processing time. To expand to. The processing in steps S142 to S146 is the same as that in steps S81 to S85 in the third embodiment, and a description thereof will not be repeated.
[0058]
On the other hand, in step S141, if the transfer time of the bitmap data is smaller than or less than a certain threshold, it is more advantageous in terms of the processing time to execute the development into the image data on the document processing apparatus main body side. Therefore, the process proceeds to step S147, and the main body develops the image. The processes in steps S147 to S149 are the same as the processes in steps S86 to S88 of the third embodiment, and a description thereof will not be repeated.
[0059]
As described above, according to the third to fifth embodiments, a device for developing font data into image data is appropriately selected, and is required for printing a high-quality document requiring a large amount of font data. Processing time can be minimized.
[0060]
The present invention may be applied to a system including a plurality of devices or an apparatus including a single device. Needless to say, the present invention can also be applied to a case where the present invention is achieved by supplying a program for causing a system or an apparatus to execute a process defined by the present invention.
[0061]
【The invention's effect】
As described above, according to the present invention, it is possible to appropriately select whether to execute expansion of a font image on the document processing apparatus side or on the printer side, and it is possible to perform printing efficiently. It becomes.
