Description

  The present invention relates to a recording system, a control apparatus, an image forming apparatus, and a display method that perform recording on a single recording medium using a plurality of recording apparatuses.

  In recent years, as a use application of a recording apparatus, a demand for recording on a cardboard box for delivery is increasing. When recording on a cardboard box, it is necessary to record in a different area according to the crease with the cardboard box unfolded.

  Patent Document 1 proposes a recording system that divides one page into a plurality of recording areas and performs individual recording settings for each of the divided recording areas.

JP 2012-203647 A

  When the developed cardboard box is one page, the size per page is larger than the size that can be recorded by a general consumer recording device. In such a case, it is conceivable to perform recording by arranging a plurality of recording means for one developed cardboard box. However, when a plurality of recording means are arranged, the area that can be recorded by the plurality of recording means does not necessarily cover the entire recording area of one page. That is, an area that cannot be recorded by the recording means (non-recordable area) may occur.

  In this case, in the conventional recording system, it is possible to clearly indicate to the user the recording area that can be recorded by each recording apparatus. However, it is assumed that the entire surface of one page can be recorded, and it is clearly indicated which portion of one page corresponds to a portion that cannot be covered by the recording area that can be recorded by the recording apparatus (non-recordable region). I can't. In other words, the user must perform recording without clearly indicating the completed design including the arrangement of the non-recordable area after recording. If the adjustment of the recording contents is inappropriate, the user needs to perform recording again after recording. In some cases, cardboard and ink were consumed in vain.

  Therefore, the present invention provides a recording system, a control apparatus, an image forming apparatus, and a display method capable of displaying appropriate recording contents to a user when recording is performed using a recording system in which a plurality of recording units are arranged. The purpose is to provide.

  For this reason, the recording system of the present invention includes a plurality of recording means capable of recording on the same recording medium, and a display means for displaying the position of a non-recordable area generated between the areas on which the plurality of recording means can record in the recording medium. It is characterized by having.

  According to the present invention, when recording is performed using a recording system in which a plurality of recording devices are arranged, appropriate recording contents can be displayed to the user.

The recording system includes a host PC 101 that is an information processing apparatus that generates recording data, recording apparatuses 102A and 102B that record recording data according to an instruction from the host PC 101, and a connection cable that connects the host PC 101 and the recording apparatuses 102A and 102B. 103. In the present embodiment, each of the recording devices 102A and 102B is provided so as to be movable, and is arranged at a predetermined position so that recording can be performed on a predetermined area of the cardboard recording medium 104 to be conveyed. Of the recording area 105 on the recording medium 104, the recording area 105A is an area that can be recorded by the recording apparatus 102A, and the recording area 105B is an area that can be recorded by the recording apparatus 102B. The recording apparatuses 102 </ b> A and 102 </ b> B of this embodiment are liquid discharge recording apparatuses that include a recording head and perform recording by discharging liquid from the recording head to the recording medium 104. During recording, liquid is ejected from the recording head as the recording medium 104 is conveyed.

  FIG. 2 is a block diagram showing a recording system in which the host PC 101 and the recording apparatus 102 are connected to each other. In the host PC 101 as an information processing apparatus, the main CPU 220 executes various programs under the control of an operating system (OS). The system bus of the main CPU 220 has a hierarchical bus via a PCI bus and an ISA bus as local buses, and a host / PCI bridge 221 and a PCI / ISA bridge 228, respectively, and is connected to each hardware. Note that the system bus of the main CPU 220 has a high-speed memory (not shown) called an L2 cache, and stores codes and data that the main CPU 220 always accesses.

  The main memory 222 is also used as a temporary storage area for execution programs such as an operating system (OS), application programs, printer drivers (hereinafter also simply referred to as drivers), and a working memory area for executing each program. The main memory 222 then converts the RGB image data drawn by the application program and the RGB image data into color signals (cyan, magenta, yellow, and black in this embodiment) corresponding to each recording head of the recording apparatus 102. Signals etc. are also memorized. All the recording data and the like are expanded on the main memory 222 and transferred to the recording apparatus 102 via the communication interface 223.

  A communication interface 223 with the recording apparatus 102 is connected to a PCI bus, and the interface used is, for example, a USB or a network. The CRTC 224 is a video controller and continuously reads display bitmap data written in the VRAM 225 by the CPU 220 and continuously transfers it to a display 226 such as a CRT, LCD, PDP or the like.

  The ROM 229 stores a basic input output system (BIOS) program for controlling input / output devices such as a keyboard, mouse 232, and FDD 231, initialization at power-on, a self-diagnosis program, and the like. The EEPROM 230 is a rewritable nonvolatile memory for storing various parameters used permanently, and is also used for storing recording characteristic data of the recording head, which is characteristic data of the present invention.

  An operating system (OS), various application programs, and a driver that implements the present invention are read from an HDD (Hard Disc Drive) 227 to the main memory 222 and executed.

  The recording device 102 constituting the recording system is controlled by the CPU 201 executing a control program stored in the ROM 203, and includes a RAM 202 for storing recording data and a communication device 204 for communicating with the host PC 101. Further, the recording apparatus 102 performs writing from the recording head control unit 205 that controls the driving of the recording head, the apparatus driving unit 206 that controls the driving of the actuator that transports the recording medium, and the memory 208, 209, 210, and 211 in the recording head. A memory R / W circuit 207 is provided. In this embodiment, for example, an EEPROM that is a rewritable nonvolatile memory is used as the memories 208, 209, 210, and 211 in each recording head.

  The recording apparatus 102 used in this embodiment includes a recording head corresponding to four colors of cyan, magenta, yellow, and black.

  FIG. 3 is a diagram showing a recording sequence using the recording system of the present embodiment. Hereinafter, main processing when recording is performed using the recording system of the present embodiment will be described with reference to FIG. Note that the subject in the processing here is the user (U), the application (A), the driver (D), and the recording device (P), and the initial of the processing number indicates the subject of each processing.

  In step U001, the user starts an application. The application here is a general-purpose application such as Microsoft Office of Adobe or Photoshop of Adobe, and can lay out desired image data and text data and can instruct recording to the printer driver. Therefore, the application may be activated by opening a file associated with the application by the OS at the time of activation, or a new layout file may be designed after the application is activated. Note that the present invention can be applied even if the application is uniquely created as long as a recording instruction can be given to the driver. Thereafter, in step U002, when the user completes the design for the layout file, the user instructs the application to start recording settings. Generally, a button such as “print” or “record setting” on the menu of the application is pressed. Here, the recording setting in the present embodiment is a setting for changing the recording direction, the recording medium size, and the like.

  Next, in step A001, the application receives the instruction in step U002 and instructs the driver to display a recording setting dialog in order to make the user perform recording settings. In step D001, the driver acquires device information (acquisition information and boundary information acquisition) from the connected recording device as information for displaying the recording setting dialog in support of step A001. This device information includes arrangement information and boundary information for configuring the recording area. In addition, when there are a plurality of recording apparatuses constituting the recording system, device information for the number of connected devices is acquired. In the present embodiment, as shown in FIG. 1, information is acquired from two connected recording apparatuses 102A and 102B, respectively. The acquisition of the device information may be automatically performed when the recording apparatus 102 is newly connected, or may be manually performed by the user at an arbitrary timing. If the recording device does not have a device information return capability, the user may set the corresponding information in the driver in advance.

  Thereafter, in step P001, the recording apparatus receives the instruction in step D001 and returns device information to the driver. In step D002, the driver receives the device information acquired in step D001, and displays a recording setting dialog for setting various recording conditions. Here, the information that can be set for the user is the individual recording that is displayed based on the common recording settings applied to the entire recording target page such as the number of recordings and the entire size of the recording medium, and the boundary information There are individual recording settings such as recording medium type and color adjustment applied to the area. Further, if there is an area other than the individual recording area, that is, an area that cannot be recorded based on the arrangement of the recording apparatus, the area is clearly designated as a non-recordable area. Note that the setting items included in the common recording setting and the individual recording setting may change the number and contents of the setting items according to the characteristics of the device connected to the recording system.

  Next, in step U003, the user operates the recording setting dialog displayed in step D002, and changes the setting of recording conditions as necessary. Further, by confirming the positions and sizes of the individual recording area and the non-recordable area in the entire recording medium, it is possible to confirm whether the layout file design of the application is appropriately arranged with respect to the recording area. In general, after changing the parameters of each recording setting item to an arbitrary value, pressing the buttons such as “Apply” and “OK” prepared on the recording setting dialog will change the recording settings to the driver. Reflect.

  Next, in step D003, the driver saves the parameters of each recording setting item set by the user in step U003 as recording setting information. Thereafter, in step U004, when the user finishes setting the recording condition in step U003, the user instructs the driver to end the recording setting. In general, a button such as “×”, “OK”, or “Cancel” prepared on the recording setting dialog is pressed to close the dialog. The “OK” button here is the same as the “OK” button in step U003. In step D004, the driver receives an instruction from the user in step U004 and ends the display of the recording dialog.

  Thereafter, in step A002, the application requests acquisition of OS standard recording setting information in order to confirm the recording setting of the driver updated by the user in step U004. The OS standard recording setting information here refers to information that can be obtained and recognized equally by a general-purpose application using common means. For example, there are recording medium size, recording direction, resolution, and number of copies included in the basic Devmode. Information that is not an OS standard such as arrangement information and boundary information handled by the driver of the present invention cannot be recognized from a general-purpose application. In step D005, the driver returns the OS standard recording setting information to the application in response to the request from the application in step A002. Thereafter, in step A003, the application updates the design file information and the UI display information on the application in accordance with the OS standard recording setting information acquired from the driver.

  Next, in step U005, the user confirms the layout of the design file updated by the application in step A003, and adjusts the layout as necessary. In general, the layout is greatly affected when the recording direction or the recording medium size information is changed. Therefore, the drawing object is resized and arranged. Further, here, since the user confirms the position and size of the individual recording area in step U003, the resize and arrangement of the drawing object can be adjusted accordingly. Thereafter, in step U006, when the user finishes the layout adjustment of the design file in step U005, the user instructs the application to execute recording. In general, this process is instructed to execute recording by pressing a “print” button prepared on the application menu.

  Next, in step A004, the application executes a recording command to the driver according to the recording execution instructed by the user in step U006. Here, the recording command refers to a general method in Windows OS in which image data composed of RGB values is drawn by the Windows API using the design file as original data. Thereafter, in step D006, the driver converts the RGB value image data transmitted by the application in step A004 into recording data interpretable by the recording apparatus, and transmits the recording data to the recording apparatus. At this time, the image data is processed for each recording area in accordance with the recording setting stored in step D003, and the recording data is divided and transmitted to the recording apparatus corresponding to the area. The process in which the application executes the recording command will be described in detail with reference to FIG.

  Next, in step P002, the recording apparatus receives the recording data transmitted in step D006 and outputs it to the recording surface.

  In the sequence of FIG. 3, the operation related to the Windows OS uses a known general method, and thus the description of the processing is omitted.

  4A and 4B are diagrams showing the configuration of the arrangement information and boundary information acquired by the driver from the recording apparatus, and FIG. 4A shows the arrangement information and boundary information. 4 (b) is a diagram showing arrangement information and boundary information in a data format stored in advance in a memory area of the recording apparatus. The recording head A is a recording head mounted on the recording apparatus 102A, and the recording head B is a recording head mounted on the recording apparatus 102B. The recording area corresponding to the recording head A is the recording area PA400, and the recording area corresponding to the recording head B is the recording area PA410. In the present embodiment, the recording apparatuses 102A and 102B are arranged in a direction that intersects the conveyance direction in which the recording medium is conveyed.

  As a parameter of the boundary information, an ID indicating an order of arrangement from the reference point is ID400 as the arrangement information acquired from the recording apparatus 102A. As boundary information, the recording medium size width corresponding to the recording head A is PA401, the recording medium size height is PA402, the recording medium size left margin is PA403, the recording medium size right margin is PA404, and the recordable area Is set to PA405. Further, as boundary information, the upper margin is PA406, the lower margin is PA407, and the height of the recordable area is PA408.

  Similarly, as the arrangement information acquired from the recording apparatus 102 </ b> B, ID 410 indicating the number of arrangement from the reference point is ID410. Also, as boundary information, the recording medium size width corresponding to the recording head B is PA411, the recording medium size height is PA412, the recording medium size left margin is PA413, the recording medium size right margin is PA414, and the recordable area Is set to PA415. Further, as boundary information, the upper margin is PA416, the lower margin is PA417, and the height of the recordable area is PA418. Each parameter of such arrangement information and boundary information is stored in advance in a memory area of each recording apparatus in a data format such as PA 409 for recording head A and PA 419 for recording head B.

  In this embodiment, the ID that is the arrangement information is defined by a static value starting from 1, and the other parameters that are the boundary information are defined by an integer value in units of 0.1 mm of 0.1 mm. The driver then sets the width of the entire recording medium as PA 431 and the height as PA 402 from the acquired arrangement information and boundary information, and the area PA 400 in which the recording head A can record, the area PA 410 in which the recording head B can record, and the recording Impossible areas can be calculated. In FIG. 4A, the hatched portion corresponds to the non-recordable area, and is an area obtained by combining the areas of the respective recording media corresponding to the recording head A and the recording head B. The recording areas PA400, PA410 The area other than is an unrecordable area.

  FIG. 4C is a diagram showing a recording area that can be explicitly shown based on OS standard recording setting information acquired from a driver by a conventional general-purpose application using Windows API or the like. The recordable area is the recordable area PA420, and the area that cannot be recorded is a hatched portion excluding the recordable area PA420. In such OS standard recording setting information, the non-recordable area including the right margin PA 404 and the left margin PA 413 shown in FIG. That is, the non-recordable area cannot be clearly indicated only by the information on the recording area that can be acquired from the driver by a general-purpose application as in the past. However, according to the arrangement information and boundary information acquired by the driver from the recording apparatus in the present embodiment, the recording area and the non-recordable area can be clearly shown in the arrangement state after recording as shown in FIG. The user can recognize the exact finished design.

  In the present embodiment, the parameters of the boundary information when two recording apparatuses are arranged in parallel are illustrated, but the present invention is not limited to this. In other words, it is possible to set and specify more complicated recordable area and non-recordable area information by changing and adding parameter units and types as appropriate according to the arrangement and number of recording devices in the recording system. is there.

  Further, the area in which the arrangement information and the boundary information are stored is not limited to the memory area of the recording devices 102A and 102B, but is stored as a file in a predetermined location on the HDD of the host PC. The storage area and its format are not limited as long as it can be referred to.

  FIG. 5 is a diagram showing an example of a recording setting dialog displayed by the driver. Hereinafter, each item of the recording setting dialog will be described.

(Common record setting D501)
The common recording setting D501 makes it possible to set recording setting items that apply to the entire recording page, such as the entire recording medium size, recording direction, number of copies, and resolution of the recording medium.

(Individual record setting D502)
The individual recording setting D502 makes it possible to set recording setting items that are applied to individual recording areas such as the type of recording medium, color adjustment, and halftone. Also, the arrangement of the individual recording areas and the boundary information are clearly shown.

(Region A D503)
The area AD503 is a tab sheet for performing individual recording settings for the area A. Region A shows the PA 400 in FIG.

(Region B D504)
The area B D504 is a tab sheet for performing individual recording settings for the area B. Region B indicates the PA 410 in FIG.

  In this embodiment, as shown in FIGS. 5A and 5B, the user switches the tab sheet between D503 and D504, so that the type and color adjustment of the recording medium and halftone are individually performed for each region. Recording settings such as settings can be made.

(Recordable area D505)
A recordable area D505 clearly indicates areas A and B that are recordable areas and a non-recordable area. The area indicated by the checkered pattern in FIG. 5 indicates a non-recordable area indicated by PA404 and PA413 in FIG. In the conventional general-purpose application, since the driver does not acquire the position information from the recording apparatus, it is possible to determine only the non-recordable area based on the top, bottom, left, and right margins. For this reason, it is impossible to clearly indicate a non-recordable area that exists between a plurality of recording means, such as the area indicated by the checker pattern in FIG.

  On the other hand, in the recording setting dialog according to the present embodiment, the arrangement information and the boundary information can be acquired from the recording device, and can be visually specified as shown in FIG. 5 based on the information.

(Region size D506)
The area size D506 specifies the sizes of the area A, the area B, and the non-recordable area. The non-recordable area is an area that cannot be specified by a conventional general-purpose application. In the configuration of the present embodiment, the non-recordable area occurs between area A and area B, that is, at a position adjacent to the recordable area in the horizontal direction. For this reason, the width information is shown in the order of arrangement for each of the recordable area and the non-recordable area.

  In this way, the user can perform desired recording settings for each of the individual recording areas. Further, in this embodiment, since the arrangement of the individual recording area and the non-recordable area that are not clearly specified in the conventional general-purpose application can be confirmed, the user can accurately recognize the completed design after recording, and the layout data Relocation can be performed.

  It should be noted that the setting items included in the common recording setting and the individual recording setting can be changed in type, number of items, and contents according to the characteristics of the device connected to the recording system. Further, a UI control method or the like may take a method other than that shown in the present embodiment.

  FIG. 6 is a flowchart showing a recording command generation process in the driver accompanying the recording process when a recording command is received. Hereinafter, the recording process in the present embodiment will be described using this follow chart. The recording command generation process is a process in which the driver converts RGB value image data transmitted from the application via the Windows OS into recording data that can be interpreted by the recording apparatus, and transmits the recording data to the recording apparatus.

When the driver receives a recording command from the OS in step S601, the recording process is started. Thereafter, in step S602, it is acquired how many pixels each of the width and height of the image data received from the OS as a recording target by the driver is. In step S603, based on the size of the image data acquired in step S602, the driver instructs the driver to receive the image data from the OS by dividing the band. As a band division unit, a plurality of rasters are divided into one or more bands with one raster as one band.
Note that step S603 is a process for saving memory consumption. If the host PC can secure a sufficient memory capacity, the image data may be received at one time without being divided into bands.

  In step S604, the driver acquires arrangement information and boundary information from the recording devices that constitute the recording system. In step S605, it is determined whether the placement information and the boundary information have been successfully acquired. If the acquisition has succeeded, the process proceeds to step S606. If the acquisition has failed, the process proceeds to step S618. If the acquisition is successful and the process proceeds to step S606, it is determined whether the existing arrangement information and boundary information previously acquired and stored by the driver are equivalent to the arrangement information and boundary information acquired in step S605. If it is determined that they are equivalent, the process proceeds to step S607, and if it is determined that they are different, the process proceeds to step S619. Note that it is determined that there is no difference between the existing arrangement information and the boundary information, and the process proceeds to step S619.

  If it is determined in step S606 that they are equivalent, and the process proceeds to step S607, the variable n is initialized to 0. This variable n is a variable for managing the number of bands acquired by band division. In step S608, 1 is added to the variable n to update the band to be processed. Thereafter, in step S609, band data of the nth band is acquired from the OS. In step S610, the acquired band data is divided by existing arrangement information and boundary information stored in the driver. In step S611, it is determined whether or not individual recording has been set for the individual recording area. When the individual recording setting is performed, the process proceeds to step S612. When the individual recording setting is not performed, the process proceeds to step S613.

  If it is determined in step S611 that the individual recording setting has been made, in step S612, image processing such as color adjustment and halftone is performed on the image data in the individual recording area based on the individual recording setting. If it is determined in step S611 that the individual recording setting has not been made, in step S613, image processing such as color adjustment and halftone is performed on the image data in the individual recording area based on the recording setting provided by the driver as a default. I do.

  Thereafter, in step S614, a recording command is generated based on the divided band data, and is transmitted to the recording apparatus corresponding to each recording area. In step S615, it is determined whether the currently processed band is the last band. If it is the final band, the process proceeds to step S616. If it is not the final band, the process returns to step S608, and the process is repeated with the next band as a processing target.

  If acquisition of arrangement information and boundary information fails in step S605 and the process proceeds to step S618, the recording process is canceled as an error in step S618.

  If it is determined in step S606 that they are different and the process proceeds to step S619, in step S619, the user is notified that the arrangement information and the boundary information have changed. As an example, FIG. 7 shows a message indicating that the arrangement information and the boundary information have changed.

  The confirmation of the recordable area in the recording setting dialog is synonymous with the process from step U002 to step U003 in FIG. 3, and in this process, the arrangement of the recording apparatus that is connecting the driver arrangement information and the boundary information. Information and boundary information are updated.

  The process moves from step S619 to step S620, and the result of instructing whether or not to continue recording by the user in the message dialog displayed in step S619 is determined. If it is instructed to continue recording, the process proceeds to step S621. If it is instructed to stop recording, the process proceeds to step S622. In step S621, the driver arrangement information and boundary information are updated to the arrangement information and boundary information of the connected recording apparatus. If the process proceeds from step S620 to step S622, an error occurs and the recording process is stopped. Further, when the process proceeds from step S615 to step S616, the recording process ends.

  FIG. 8 is a diagram schematically showing the form of image data in the image data generation of this embodiment. S700 is image data to be subjected to recording processing when the driver receives a recording instruction from the OS. When the image of S700 is received as 1000 raster band data per band as an image of 3000 rasters, the image data is divided into 3 bands. S701 indicates band data acquired by the driver from the OS, and is obtained by dividing the image data of S700 into three (n = 3). S702 shows an example in which the driver divides the band data acquired from the OS into individually recordable areas by arrangement information and boundary information. Here, the hatched portion becomes a non-recordable area and is not a target of the recording process in the subsequent processes. S703 shows an example in which the driver transmits the recording data generated to the recording apparatus. Here, it is assumed that the image data 1a, 2a, 3a is recorded by the recording device 102A, and the image data 1b, 2b, 3b is recorded by the recording device 102B. And send it as a command.

  Thus, in the recording setting, the recording area and the non-recordable area that cannot be recorded by the recording apparatus are clearly indicated. As a result, when recording is performed using a recording system in which a plurality of recording devices are arranged, it is possible to realize a recording system capable of displaying appropriate recording contents to the user.
