Description

  The present invention relates to a printer driver drawing control technique.

In the Microsoft printing system, a graphics engine called GDI (Graphic Device Interface) has been used. A conventional print processing flow using GDI is as follows.
1) In response to a print instruction from a user, a GDI application (hereinafter referred to as “GDI application”) calls a GDI service function group to issue a drawing command.
2) The issued GDI drawing command is spooled as drawing data and passed to a printer driver for GDI (hereinafter referred to as “GDI driver”).
3) The GDI driver converts drawing data composed of GDI drawing commands (hereinafter referred to as “GDI format drawing data”) into print data (so-called PDL data) that can be interpreted by the printing apparatus. Output.

  Such a processing flow for printing from the GDI application via the GDI driver is referred to as a “GDI print pass”. In recent years, a new print processing flow called an XPS print path has been added to the GDI print path. XPS is an XML-based electronic document format and is an abbreviation for XML Paper Specification. In the XPS print path, drawing data in the XPS format is generated by an application that handles XPS (hereinafter referred to as “XPS application”), and the print data is generated by an XPS printer driver (hereinafter referred to as “XPS driver”). It is converted and output to the printing device.

  The GDI print path and the XPS print path are not in an exclusive relationship. For example, the GDI format drawing data generated by the GDI application using GDI is converted into the XPS format drawing data, and the XPS driver converts the drawing data to the print data. Is possible. Conversely, it is also possible to convert the drawing data in the XPS format by the XPS application into drawing data in the GDI format and use the GDI driver as print data. That is, there is a print processing flow for printing from the GDI application via the XPS driver and a print processing flow for printing from the XPS application via the GDI driver. For example, when printing is performed from an GDI application using an XPS driver, GDI format drawing data is converted into XPS format drawing data by the conversion module. This conversion module is called MXDW (Microsoft XPS Document Writer). The drawing data converted into the XPS format is stored in the XPS spool file, and then converted into print data by the XPS driver.

  As described above, four print processing flows can be used in the OS after Windows (registered trademark) Vista. Accordingly, if either the GDI driver or the XPS driver is prepared, it is possible to cope with the printing process of the drawing data generated by both the GDI application and the XPS application.

  However, since the specifications differ between the XPS format and the GDI format, there are various problems in the format conversion of drawing data. As an example, there is a problem that a print request in which a print image is allocated to a portion that protrudes from the printable area is issued from the GDI application to the XPS driver. To solve this problem, a technique for controlling whether drawing data in the XPS format input to the XPS driver is derived from the GDI application or from the XPS application and is printed in the printable area. Has been proposed (Patent Document 1).

JP 2008-276745 A

  As a problem in drawing data format conversion, in addition to the problems described above, it has become clear that there is a problem related to drawing of objects having graphic attributes. For example, when an object width = 0 is specified by a drawing command for an object with a graphic attribute, there is a problem that an object (for example, a line) is not drawn by a printer driver. This problem is caused by the fact that object width = 0 in the GDI format means the smallest width that can be displayed on the device, whereas object width = 0 in the XPS format means that the object is not drawn at all. . In other words, if the drawing data that the GDI application generates via GDI includes a drawing command that specifies drawing of a line with object width = 0, the line is drawn if printing is performed with the GDI driver, whereas XPS Lines are not drawn when printing with the driver. That is, even if the same drawing command is issued from the same GDI application, if the print result differs depending on the type of printer driver to be used for a predetermined graphic drawing command, the print quality is greatly affected. It will be.

  An information processing apparatus according to the present invention is an information processing apparatus including a printer driver that generates print data corresponding to a printing apparatus from input drawing data in an XPS format, and the printer driver It is determined whether the drawing data in the XPS format is the drawing data in the XPS format converted by the conversion module from the drawing data in the GDI format generated based on the printing process of the GDI application, and the input drawing in the XPS format is performed. It is determined whether the data includes a predetermined graphic rendering command, and as a result of the determination, the input XPS format rendering data is obtained from the GDI format rendering data generated based on the printing process of the GDI application. Drawing data in XPS format converted by the conversion module, and the predetermined group If it is determined that the graphic drawing command is included, the predetermined graphic drawing command is changed to a graphic drawing command that designates drawing that can be expressed by the printing apparatus, and based on the drawing data including the changed graphic drawing command. The print data is generated.

  According to the present invention, in a printer driver (XPS driver) that generates print data corresponding to a printing apparatus from input drawing data in XPS format, the input drawing data in XPS format is subjected to printing processing of a GDI application. When the generated GDI format drawing data is converted into XPS format drawing data by a predetermined conversion module and includes a predetermined graphic drawing command, the predetermined graphic drawing command is received by the printing apparatus. Change to a graphic drawing command that designates a specific drawing that can be expressed, and generate print data based on the drawing data including the changed graphic drawing command, so that the same drawing command from the GDI application is used. Printer driver type is XPS driver Depending whether the GDI driver can be prevented from difference in print results occurs.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following embodiments do not limit the invention according to the claims, and all combinations of features described in the embodiments are not necessarily essential to the solution means of the invention.

[Example 1]
FIG. 1 is a functional block diagram illustrating an example of a configuration of an information processing apparatus that generates print data according to the present embodiment. An operating system (hereinafter referred to as OS) (not shown) is installed in the information processing apparatus 100. In this embodiment, Windows (registered trademark) is assumed as the OS. In the information processing apparatus 100, two types of drawing software, a GDI application 110 and an XPS application 120, operate on the OS as software for generating drawing data. The GDI application 110 receives a print instruction from the user, calls a GDI function, and uses the GDI 111 to generate drawing data in GDI format according to the object attributes (characters, graphics, images, etc.). The GDI 111 is generally called a graphics engine. The drawing data in the GDI format is sent to the MXDW 112 because the XPS driver 130 cannot accept the input as it is. The MXDW 112 is a GDI-XPS conversion means, and is a module that converts drawing data in the GDI format into drawing data in the XPS format, and is provided by the OS. The drawing data converted into the XPS format by the MXDW 112 is input to the XPS driver 130. The XPS application 120 directly generates drawing data in the XPS format. The drawing data in the XPS format may be generated via a graphic engine called WPF (Windows Presentation Foundation), but this is not relevant to the features of the present invention, and will not be described. The drawing data in the XPS format generated by the XPS application 120 is input to the XPS driver 130 as it is.

  The XPS driver 130 is a printer driver that accepts only XPS format drawing data as input drawing data. The XPS driver 130 manages print settings such as the number of copies to be printed and the paper size, and generates print data (PDL data) that can be interpreted by the printing apparatus from the input drawing data. The print data generated by the XPS driver 130 is transmitted to the printing apparatus via the spooler 140. The XPS driver 130 includes a UI driver 131, a graphics driver 132, and a setting data holding unit 133. The UI driver 131 displays a user interface screen (hereinafter referred to as a UI screen) of the XPS driver 130 and stores information related to print settings input by the user. The graphics driver 132 generates print data from the drawing data in the XPS format based on the print setting information set by the user with the UI driver 131. Details of the UI driver 131 and the graphics driver 132 will be described later. The setting data holding unit 133 holds various setting data related to printing, which the XPS driver 130 refers to when generating print data. This setting data is described in the XML format and includes information related to operation settings of the UI driver 131 and the graphics driver 132. In this embodiment, information related to a search character string for determining the type of application is held as part of setting data, and is referred to when print data is generated.

  FIG. 2 is a block diagram illustrating an example of a hardware configuration of the information processing apparatus 100. The configuration illustrated in FIG. 2 is an example, and the information processing apparatus 100 may be a single device or a system including a plurality of devices connected via a network such as a LAN or a WAN. The information processing apparatus 100 implements various processes when the CPU 201 executes a processing program stored in the ROM 206 or the hard disk 203, and comprehensively controls each unit connected to the system bus 210. Further, the CPU 201 executes various processes such as opening a pre-registered window based on a command instructed with a mouse cursor or the like. For example, when the user gives an instruction to execute printing, a print setting window is opened and various settings for the XPS driver 130 are performed. The RAM 202 functions as a main memory, work area, and the like for the CPU 201. The hard disk 203 stores an OS, a boot program, various applications, font data, user files, edit files, and the like. The XPS driver 130 is also stored in the hard disk 203. The display controller 204 controls display on a display (not shown). The printer controller 205 is connected to the printing apparatus via a predetermined bidirectional interface (not shown) and is responsible for communication control with the printing apparatus. Note that the CPU 201 executes, for example, outline font development (rasterization) processing on the display information RAM set on the RAM 202 to enable WYSIWYG on the display. The external storage drive 207 controls access to a storage medium such as a CD or a DVD. A keyboard controller 209 controls key input from a keyboard or pointing device.

  Next, details of the UI driver 131 will be described. FIG. 3 is a diagram illustrating an example of an internal configuration of the UI driver 131. The UI driver 131 includes a UI display unit 301, a UI setting unit 302, a driver initialization unit 303, and a driver handle return unit 304.

  The UI display unit 301 displays a UI screen for the user to make print settings on the display. The UI setting unit 302 stores print settings set or changed by the user via the UI display unit 301. The driver initialization unit 303 initializes the UI driver 131. When a driver initialization instruction is received from the application or GDI 111, the driver handle generated by the initialization process is passed to the application or GDI 111. The driver handle is an identification name for uniquely identifying the driver. The driver handle generated by the initialization process is returned to the application that issued the initialization instruction by the driver handle return unit 304. The application that has received the driver handle permits the user to input print settings and outputs drawing data to the XPS driver 130. Note that a UI screen display instruction may be passed to the UI driver 131 together with a driver initialization instruction in order for the user to perform print settings. In that case, a UI dialog is displayed on the UI display unit 301.

  Next, details of the graphics driver 132 will be described. FIG. 4 is a diagram illustrating an example of the internal configuration of the graphics driver 132. As described above, the graphics driver 132 receives drawing data in XPS format (hereinafter referred to as “XPS data”), generates print data corresponding to the print setting information, and sends it to the printing apparatus via the spooler 140. It has a function to transmit. The graphics driver 132 includes an XPS analysis unit 401 and a print data generation unit 402.

  In the XPS data input from the MXDW 112 or the XPS application 120, all document information is described in XML, and a plurality of files for each description content are combined into one by ZIP compression. The input XPS data is analyzed after being decompressed by the XPS analysis unit 401. The contents of the analysis include, for example, a determination process of whether the input XPS data is derived from the GDI application 110. Details of the analysis processing will be described later. The XPS analysis unit 401 also generates intermediate data that is data at the previous stage of the print data. The print data generation unit 402 generates print data (PDL data) based on the intermediate data and the print setting information. The generated print data is output to the spooler 140.

  Next, the print data generation process in the XPS driver 130 according to the present embodiment will be described in detail. FIG. 5 is a flowchart showing the flow of print data generation processing. This print data generation process starts in response to a print instruction to the XPS driver 130. Specifically, a predetermined program stored in the ROM 206 is developed in the RAM 202 in accordance with a user's print instruction, and is realized by the CPU 201 executing it.

  In step 501, XPS data is input to the XPS driver 130 from the MXDW 112 or the XPS application 120. The input XPS data is sent to the XPS analysis unit 401 in the graphics driver 132. At this point, the XPS data is in the ZIP format. When the XPS driver 130 accepts the input of XPS data, it was input directly from the XPS application 120, or the drawing data that was originally in the EMF format was input after being converted into the XPS format by the MXDW 112 I don't know if it's something. Therefore, in order to identify whether the input XPS data is derived from the GDI application 110 or the XPS application 120, an application determination process is performed in step 503 described later.

  In step 502, the XPS analysis unit 402 decompresses the ZIP format XPS data. FIG. 6 shows the data structure of XPS data. The XPS data has a tree structure, and a plurality of folders such as “Metadata”, “_rels”, and “Documents” exist in the first hierarchy under the root folder.

  In step 503, the XPS analysis unit 402 performs an application determination process. This application determination process is a process for determining whether the application that generated the input XPS data is the GDI application 110 or the XPS application 120. Details of the application determination process will be described later. As a result of the determination, if the generation source application is the GDI application 110, the process proceeds to step 505. On the other hand, if the generation source application is the XPS application 120, the intermediate data is generated as it is without changing the drawing command, and the process proceeds to step 507.

In step 505, the XPS analysis unit 401 determines whether or not a drawing command in which 0 is specified as the width of the graphic attribute object exists in the page unit file in the “Documents” folder obtained by decompression. To do. “1.fpage” and “2.fpage” shown in FIG. 6 are files in page units, and include, for example, a “Path” drawing command shown below.
<Path Data = "F1 M 19.2,19.2 L 96,19.2" Stroke = "# ffff0000" StrokeThickness = "0" StrokeLineJoin = "Round" StrokeStartLineCap = "Round" StrokeEndLineCap = "Round" Clip = "M 0,0 L 0 , 1083.84 755.2,1083.84 755.2,0 z "/>

  The “Path” is a command for designating line drawing, and each element represents the setting contents of line drawing. For example, the Data element represents moving (M) to the coordinates (19.2, 19.2) and drawing the line (L) with respect to (96, 19.2). The element related to the line width as the object width is “StrokeThickness”, which means that the element value is “0”, that is, the XPS specifications do not draw a line.

  As a result of the determination, if there is a graphic drawing command with an object width of 0, the process proceeds to step 506. On the other hand, if there is no graphic drawing command with an object width of 0, intermediate data is generated without changing the drawing command in the file, and the process proceeds to step 507.

In step 506, the XPS analysis unit 401 performs a process of changing a graphic drawing command having an object width of 0 to a graphic drawing command for designating drawing of an object (for example, a line object) with the minimum width. For example, in the case of the above-mentioned “Path” drawing command, the following changes are made.
<Path Data = "F1 M 19.2,19.2 L 96,19.2" Stroke = "# ffff0000" StrokeThickness = "0.16" StrokeLineJoin = "Round" StrokeStartLineCap = "Round" StrokeEndLineCap = "Round" Clip = "M 0,0 L 0 , 1083.84 755.2,1083.84 755.2,0 z "/>

In the case of the above specific example, the element value “0” of “StrokeThickness” is changed to “0.16”, which means that a line is drawn with a width of 0.16 (unit is point).
In this way, the graphic drawing command with the object width of 0 is not interpreted as not being drawn as it is according to the XPS specification, but is re-interpreted as the content of drawing in the minimum unit of the device according to the GDI specification. Be changed. The specific flow of this drawing command change process will be described later. Then, based on the result of the rendering command change process or in the course of the rendering command change process, intermediate data is generated and sent to the print data generation unit 402.

  In step 507, the print data generation unit 402 generates print data based on the intermediate data and the print setting information. The generated print data is sent to the spooler.

  The above is the content of the print data generation process in the XPS driver 130. As described above, EMF (GDI) and XPS have different specifications, and print data is generated according to the type of generation application for graphic drawing with an object width = 0. Printing can be performed.

  Next, details of the application determination process (step 503) in the flowchart of FIG. 5 described above will be described. In the application determination process of the present embodiment, generation of XPS data input to the XPS driver is performed by searching for a specific character string from a predetermined file in drawing data in XPS format in accordance with information on a preset search condition. Identify the original app. FIG. 7 is a flowchart illustrating details of the application determination process according to the present embodiment.

  In step 701, setting information related to a search character string for specifying a generation source application is acquired from the setting data holding unit 133. FIG. 8A shows an example of search character string setting information acquired in this step, which specifies which part (file) in the XPS data is to be searched for. In the search character string setting information shown in FIG. 8A, the Setting element 801 which is a unit of the search condition further includes three elements “SearchString”, “SearchPath”, and “Mode”. “SearchString” is an element that designates a character string to be searched, and here, “microsoftxpsdocumentwriter”, which is a character string representing MXDW 112, is set as its value. This character string indicating the MXDW 112 is described in the job level print ticket in the MXDW 112 when converting from the EMF format to the XPS format. Therefore, the XPS data having the print ticket including this character string can be determined to be generated by the GDI application 110. Note that it is not limited to “microsoftxpsdocumentwriter” as long as it is a character string representing MXDW112.

  “SearchPath” is an element for designating a path for identifying a file from which to search for a character string in XPS data. Here, “/MeaData/*_PT.xml” is set as the value. As described above, since the XPS data has a data format in which a plurality of files are ZIP-compressed, the search destination path is specified by “SearchPath” to specify which file is to be searched. As in this embodiment, by using regular expressions, a plurality of files (for example, files with file names such as “A_PT.xml” and “B_PT.xml”) can be searched. Since the file name of the job level print ticket is “JOB_PT.xml”, the character string “JOB_PT.xml” may be set as a setting value without using a regular expression. “Mode” indicates which type of application the XPS data is derived from when the search string specified by “SearchString” exists in the file corresponding to the path specified by “SearchPath”. The element to identify. Here, “cpk: GDI” is set as the value. That is, in this case, if there is a character string “microsoftxpsdocumentwriter” in the file name including “_PT.xml” in the metadata folder, it is determined that the XPS data is derived from the GDI application 110. If “cpk: XPS” is entered as the setting value of the “Mode” element, it is determined that the attribute is derived from the XPS application 120. In the example of FIG. 8 (a), only one search condition (only one Setting element) is set, but a plurality of search conditions are set and one of the search conditions (Setting element) is satisfied. In this case, the type of application may be specified. In this way, the setting information defines the content of which character string is searched from which file of XPS data and which type of application is determined when it is found. Thereby, the search condition can be changed by changing the definition in the setting information without changing the program itself.

  In step 702, it is determined whether the search character string specified by “SearchString” exists in the file indicated by the path specified by “SearchPath” according to the setting information of the search character string. FIG. 8B is a diagram illustrating an example of a print ticket as a search target file. In the example shown in FIG. 8B, the search character string “microsoftxpsdocumentwriter” is included in the “xmlns: ns0000” element of the “psf: PrintTicket” element. As a result of the determination, if a search character string exists in the target file, the process proceeds to step 703. On the other hand, if the search character string does not exist in the target file, the process proceeds to step 704.

  In step 703, it is determined that the GDI application 110 that has passed through the MXDW 112 is the generation source for the input XPS data, and this processing is finished.

In step 704, it is determined that the XPS application 120 is the generation source for the input XPS data, and the present process ends.
The above is the content of the application determination process according to the present embodiment.

  Next, details of the drawing command change process (step 506) in the flowchart of FIG. 5 described above will be described. FIG. 9 is a flowchart showing details of the drawing command change process.

  In step 901, information about the print resolution and print paper size is acquired from the print setting information set by the user. This print setting information is described in the part called the above-mentioned print ticket in the XPS data. The XPS analysis unit 401 analyzes the print ticket and acquires information about the print resolution and the print paper size. In the example of FIG. 8B, the print resolution is 100 (dpi) in the “psk: PageResolution” element, and the print paper size is a size corresponding to A4 in the “psk: PageMediaSize” element (210 mm long × 297 mm wide). Are set respectively.

  In step 902, the width of 1 pixel, which is the minimum width that can be expressed by the device, is derived from the acquired information about the print resolution and the print paper size. For example, when the print resolution is set to 100 (dpi) and the print paper size is set to A4 as described above, the number of pixels of the image is 827 pixels × 1169 pixels. In this case, about 0.25 mm is derived as the width of one pixel.

  In step 903, a graphic drawing command specifying object width = 0 (meaning “not drawing” in the XPS format) is used to specify drawing of an object with an object width corresponding to one pixel width (here, 0.25 mm). Change to instruction.

  The above is the content of the drawing command change process. With this change processing, if the generation application of the input XPS data is a GDI application, a drawing command with a content that is not drawn as it is is drawn with the minimum object width as in the GDI (EMF) specification. Changed to a drawing command.

  In the above example, the 1 pixel width is obtained by calculation. However, depending on the specifications of the printing apparatus and the print data to be generated, a dedicated drawing command for drawing a graphic attribute object such as a line with the minimum width is prepared in advance. Sometimes it is. In such a case, the derivation process in step 902 described above is omitted, and the graphic drawing command in which the object width is 0 in the print data generation (step 507) in the flow of FIG. The print data may be generated after the change. In this case, the object width is calculated on the printing apparatus side.

  In this embodiment, the printer driver installed in the information processing apparatus has only the XPS driver. However, a GDI driver may also be installed. By applying this embodiment, the same print result can be obtained regardless of which printer driver is used for the drawing data generated by the GDI application.

  According to the present embodiment, when the XPS data input to the XPS driver is derived from the GDI application, the graphic drawing command with the object width = 0 specifies drawing with the minimum width of the object in accordance with the GDI application specification. The graphic drawing command is changed. Thereby, the printing result of the content intended by the user with the GDI application can be obtained by printing via the XPS driver.

[Example 2]
In the first embodiment, a specific character string is searched from a predetermined file in XPS data in accordance with information on a preset search condition, thereby specifying an application that generates XPS data input to the XPS driver. The drawing command was changed as necessary. Next, an embodiment in which the XPS data generation source application is specified based on the settings made by the user on the user interface screen of the XPS driver used during printing will be described as a second embodiment. The basic configuration is the same as that of the first embodiment, and the following description will focus on the application determination process that is the difference from the first embodiment.

  First, a user interface screen (hereinafter, UI screen) of the XPS driver 130 used by the user during printing will be described. FIG. 10 is a diagram illustrating an example of a UI screen of the XPS driver 130. The UI screen 1000 is displayed on the display of the information processing apparatus 100 by the UI display unit 301 of the UI driver 131. At the time of printing, the user uses the UI screen 1000 as shown in FIG. 10 from a document creation application to make various print settings such as the output paper size and print orientation. In the UI screen 1000, “print (GDI-XPS compatible)” can be selected as an output mode in an “output method” item 1001 in the upper right part. This “printing (GDI-XPS compatible)” is used when the user who prints out the drawing data generated by the GDI application wants to obtain the same printing result as when printing with the GDI driver by printing via the XPS driver. This is the mode to select. When the user does not select “print (GDI-XPS compatible)” (for example, when “print (normal)” indicating normal printing is selected), the XPS specifications are all followed. That is, even if the drawing data is generated by the GDI application, in accordance with the XPS specification, the graphic drawing command with the object width = 0 is treated as a drawing command that does not draw the object.

FIG. 11 is a flowchart illustrating details of the application determination process according to the present embodiment.
In step 1201, a print ticket, which is a file in which print setting information is described, is acquired from the received XPS data, and the content is analyzed. At this time, the setting value of the output mode selected by the item 1001 of the above-described UI screen 1000 at the time of print setting is acquired. FIG. 12 is an example of a print ticket for XPS data according to the present embodiment. Here, the output method item 1001 on the UI screen 1000 is described by a “psk: OutputMode” element on the XPS data print ticket. In the example of FIG. 12, “GDI” is set as the element value of “psk: OutputMode”, which means that “print (GDI-XPS compatible)” is selected as the output method. The XPS analysis unit 401 can identify the type of application that is the generation source by reading the setting value of the “psk: OutputMode” element on the print ticket.

  In step 1102, it is determined whether or not the acquired output mode setting value (element value of “psk: OutputMode”) is “GDI”. If the result of determination is “GDI”, the processing proceeds to step 1103. On the other hand, if it is not “GDI”, the process proceeds to step 1104.

  In step 1103, it is determined that the input XPS data is the XPS data that is generated by the GDI application 110 via the MXDW 112, and this processing ends.

In step 1104, it is determined that the input XPS data is the XPS data generated by the XPS application 4, and the process ends.
The above is the content of the application determination process according to the present embodiment.

  Also in the present embodiment, as in the first embodiment, the print result of the contents intended by the user with the GDI application can be obtained by printing via the XPS driver.
