And a first detection unit that detects deletion of a file associated with an instruction to cancel the printing process from a connected external device, and the control unit includes a first detection unit. by means, if the deletion of files correspondence to the instruction for stopping the printing process is detected, this to stop the printing process of the print target file by printing means It is accomplished by a printing apparatus according to claim.

In addition, the above-described object is an area that can be referred to by a connection unit for connecting to an external device, and an external device connected through the connection unit, and a file associated with an instruction to stop the printing process. A method for controlling a printing apparatus having a storage unit having an area and a printing unit that prints a file to be printed according to print settings, and when a file is written to the area from a connected external device, control means, have a higher control engineering to be printed by the printing means the write file as the file to be printed, the control means in the control step, deleting files correspondence to the instruction for stopping the printing process is detected In this case, the printing apparatus control method is characterized in that the printing process of the file to be printed by the printing unit is stopped .

  With such a configuration, according to the present invention, it is possible to realize a printing apparatus capable of printing from an external apparatus and its control method without installing device driver software in the external apparatus.

Hereinafter, preferred and exemplary embodiments of the present invention will be described in detail with reference to the drawings.
(First embodiment)

  In the figure, a control unit 109 is a CPU, for example, and controls the overall operation of the printer 1. The RAM 105 is a memory that reads various data and a program executed by the control unit 109 and is used as a work area of the control unit 109. The ROM 103 is a non-volatile memory that stores a program executed by the control unit 109. The communication I / F 104 is an interface for communicating with an external device such as a PC 2 to be described later. In this embodiment, the communication I / F 104 is a USB interface, but is not limited thereto. Specifically, the communication I / F 104 may include one or more interfaces that support a protocol that allows the printer 1 to behave as a storage device when viewed from the connected external device (PC 2 in this embodiment).

  The storage device 106 may be a semiconductor memory or a hard disk drive. The storage device 106 includes, as at least a part thereof, an externally referable area 4 that is readable and writable from an external device that is communicably connected via the communication I / F 104. As will be described later, the printer 1 of this embodiment can behave as an external storage device having this externally referable area 4 when connected to an external device (PC 2 in this embodiment). The storage device 106 is managed by a file system 107 using, for example, FAT (File Allocation Table). The data file stored in the storage device 106 is accessed through the file system 107.

  The access monitoring unit 110 monitors the file system 107 and grasps the situation when there is an access (read request, write request) from an external device to a folder or file in the storage device 106.

  The printing unit 108 is a so-called print engine, and forms an image on a recording medium such as paper based on the control of the control unit 109 and the print data. The recording method used by the printing unit 108 is not limited, and any method such as an electrophotographic method, an ink jet recording method, or a thermal transfer method can be adopted. In the present embodiment, the ink jet recording method is used.

  The display unit 111 includes a color LCD, for example, and displays a GUI screen such as print data and operation guidance based on the control of the control unit 109.

  The operation unit 112 includes a group of input devices for receiving various instructions and settings for the printer 1 from the user, such as keys, buttons, and a touch panel provided on the display unit 111. The operation content of the operation unit 112 is transmitted to the control unit 109, and the control unit 109 performs control according to the operation content.

The control unit 109 is a CPU, for example, and controls the overall operation of the printer 1 by executing a program stored in the ROM 103.
The bus 102 connects the above-described units to each other.

(Configuration of PC2)
FIG. 2 is a block diagram illustrating a configuration example of a PC (general-purpose computer apparatus) 2 as an example of the external apparatus in the present embodiment.
In the figure, a display 201 is composed of a CRT (Cathode Ray Tube), an LCD (Liquid Crystal Display), etc., and displays various GUIs (Graphical User Interfaces), data, and the like. The keyboard 203 and the pointing device 204 are used for inputting characters and pointing to icons and buttons in the GUI. The CPU 205 controls the entire PC 2.

  A ROM 206 (Read Only Memory) stores a program (mainly a boot program) executed by the CPU 205, parameters, and the like. A RAM (Random Access Memory) 207 is used as a work area when the CPU 205 executes various programs, a temporary save area during error processing, and the like.

  A hard disk drive (HDD) 208 stores programs executed by the CPU 205 such as an OS and application programs, and stores user data. It is also used as a virtual storage area. It is assumed that programs that realize various functions of the PC 2 described in the present embodiment are stored in the HDD 208.

  A removable media drive (RMD) 209 is a device that reads / writes or reads a removable recording medium. Specific examples of the RMD 209 include a flexible disk drive, an optical disk drive, a magneto-optical disk drive, a memory card reader, and a removable HDD.

  The USB / IEEE 1394 interface 210 is an example of an interface for connecting various peripheral devices such as a printing apparatus. More specifically, the USB / IEEE 1394 interface 210 is an example of an interface that supports a protocol that the connected printing apparatus can handle as a storage device from the PC 2. Thus, it may be any one or more types of interfaces that support similar protocols. The following description will be made assuming that the interface is a USB interface for ease of explanation and understanding.

  A network interface (I / F) 211 is an interface for connecting the PC 2 to a computer network. The bus 212 includes an address bus, a data bus, and a control bus, and connects the above-described units.

(File structure of printer 1)
FIG. 3 is a diagram illustrating an example of a file configuration formed in a storage area (externally referable area) 4 that can be read and written from an external apparatus, among the storage apparatuses 106 included in the printer 1 of the present embodiment. This file structure is formed and managed by the file system 107.

As shown in FIG. 3A, in this embodiment, a printer folder 301 is formed at the highest level, and a print start folder 302, a print waiting folder 303, a printing folder 304, a printed folder 305, and a print stop are included therein. A command file 306 is provided. The printing folder 304 is provided with print cancellation files 308 and 309.
FIG. 3B shows an example of a screen in a state where the file configuration of FIG. Details of the folder shown in FIG. 3 will be described later.

(Operation when connected)
FIG. 4 is a diagram schematically illustrating an outline of a printing process using a printing system including the printer 1 and the PC 2 according to the present embodiment.
When the USB interface 210 of the PC 2 and the communication I / F 104 of the printer 1 are connected by the USB cable 3, the descriptor information is acquired with the PC 2 as the USB host and the printer 1 as the USB device.

  The printer 1 notifies the PC 2 of the USB mass storage class in the descriptor information. As a result, the PC 2 recognizes the printer 1 as a USB mass storage class device.

Thereby, in the PC 2, the printer 1 is mounted as a removable disk, and the corresponding disk icon 6 is displayed on the display 201. The OS that is currently used generally includes a USB or IEEE 1394 protocol driver as a standard. Therefore, this series of operations in the PC 2 is normally provided as an OS function, and driver installation is unnecessary.
Thus, the user of the PC 2 can handle the printer 1 as a general storage device.

  Accordingly, when the disk icon 6 is double-clicked by the pointing device 204, the printer folder 301 is displayed. When the printer folder 301 is further double-clicked, a display as shown in the upper part of FIG.

  The user drags and drops an icon of a data file (image data file 10) desired to be printed, which exists in a volume (such as HDD 208 or RMD 209) accessible from the PC 2, to the print start folder 302. The OS executed by the CPU 205 recognizes this operation as a file copy operation, reads the image data file 10 and writes it to the printer 1 acting as a removable disk.

  When the control unit 109 of the printer 1 receives the image data file 10 through the communication I / F 104, the control unit 109 writes and stores it in the print start folder 302 of the storage device 106 through the file system 107.

  The access monitoring unit 110 detects that the image data file 10 has been written in the print start folder 302 associated with the print start instruction. The access monitoring unit 110 determines whether the written file can be printed as a file to be printed based on, for example, the extension of the file.

  When the access monitoring unit 110 determines that the image data file 10 can be printed, the control unit 109 reads the image data file 10 from the print start folder 302 and print preview based on print setting information prepared in advance. Generate an image.

  Then, the control unit 109 generates a GUI screen including the generated print preview image 7 and the print setting information 8 and causes the display unit 111 to display the GUI screen. In the example of FIG. 4, the print setting information 8 is a borderless / presence setting and a print size setting, but the type and number of information are not limited to this example. The GUI screen also includes a button 113 for allowing the user to select whether to execute or cancel printing. When a touch panel is used as the operation unit 112, the button 113 itself functions as the operation unit 112. When the operation unit 112 does not include a touch panel, the user can operate the buttons and keys included in the operation unit 112 to select and execute an execution (OK) or stop button.

  Note that printing may be started immediately for a file determined to be printable by the access monitoring unit 110 without receiving user confirmation. However, when a print instruction is given by a file copy operation as in this embodiment, there is no opportunity to display a preview of the print result. Therefore, by displaying the print preview image on the display unit 111 of the printer 1 before starting printing, it is possible to prevent an erroneous file from being printed and to check print settings.

  In response to a print execution instruction from the user via the operation unit 112 of the printer 1, the control unit 109 transfers the image data file 10 that is a print target file and print setting information to the printing unit 108. The printing unit 108 generates print data based on the image data file 10 and print setting information, and executes print processing. Note that the control unit 109 may perform the generation of print data, and the printing unit 108 may perform printing based on the print data.

(Printing operation)
FIG. 5 is a flowchart for explaining the operation of the printer 1 that implements the printing process described in FIG.
The access monitoring unit 110 monitors access to the externally referable area 4 of the storage device 106 (S501). When it is detected that a file has been written in the folder associated with the print start instruction (the print start folder 302 in this embodiment) (S502, Yes), the access monitoring unit 110 can print the written file. It is determined whether the file is a valid file (S503). This determination can be performed, for example, by determining whether or not the extension of the stored file is included in the extension stored in advance as the extension of the printable file.

  Note that FIG. 5 illustrates the processing at the start of printing. Therefore, if it is not detected in S502 that a file has been written in the printing start folder 302, the processing returns to S501. For example, when a folder associated with another instruction is provided and access to the folder is detected, the processing can be appropriately branched according to the associated instruction.

  In step S <b> 503, when the access monitoring unit 110 determines that the written file is a printable file, the control unit 109 checks the paper type, ink cartridge type, and image processing settings that are loaded in the printing unit 108. (S504). Then, the control unit 109 uses the written file as a file to be printed, generates a print preview image that matches the print conditions (S505), and displays the print preview image on the display unit 111 together with the current print condition setting (S506).

  Next, the control unit 109 waits for an instruction input from the user through the operation unit 112. When the setting of the printing condition is changed (S507, Yes), the control unit 109 returns the process to S504, confirms the printing condition, and updates the display including the print preview.

  When an instruction to stop the printing process is input (S508, Yes), the control unit 109 ends the current print preparation process, returns the process to S501, and detects that a new file is stored in the print start folder 302. Wait to be done.

  When a print start instruction is input (S509, Yes), in response to this, the control unit 109 transfers the file to be printed to the printing unit 108 together with the setting contents of the printing conditions. The printing unit 108 generates print data according to the file and the printing conditions, and executes printing by controlling the inkjet recording head, the medium transport mechanism, and the like (S510). Note that, as described above, the control unit 109 may generate print data according to the print condition setting, and supply the print data to the print unit 108.

  When the normal end of the printing process is received from the printing unit 108, the control unit 109 returns the process to S501. It should be noted that a file that has been successfully printed may be deleted, or moved to a dedicated folder provided in the printer folder 301. For example, in the example of FIG. 3, the printed folder 305 can be used as the destination of a file for which printing processing has been completed. Therefore, when the control unit 109 receives a normal print end notification from the printing unit 108, the control unit 109 moves the printed file (IMG_0025.JPG) from the print start folder 302 to the printed folder 305.

  In the above description, only the case where the print start folder 302 and the printed folder 305 are used among the subfolders 302 to 305 in the printer folder 301 has been described for ease of explanation and understanding. However, other subfolders associated with the print processing status can be provided.

  For example, as shown in FIG. 3, a print waiting folder 303 and a printing folder 304 can be provided. In this case, when the file is confirmed to be printable in S503, the control unit 109 moves the file from the print start folder 302 to the print waiting folder 303. The control unit 109 moves one of the files stored in the print waiting folder 303 to the printing folder 304 and then executes the printing process. In addition, the control unit 109 moves (or deletes) a file whose printing processing has been normally completed from the printing folder 304 to the printed folder 305.

  Thus, by providing a folder according to the progress of the printing process and moving the file with the progress of the printing process, the user confirms the location of the file in the printer folder 301 on the PC 2. It is possible to check the status of the file for which printing has been instructed.

  As described above, when connected to an external device, the printing device of this embodiment behaves as a storage device accessible from the external device, and prints a transfer file by an operation of storing from the external device to the storage device. Therefore, it is possible to provide a printing apparatus that can perform printing from an external apparatus even if driver software is not installed in the external apparatus.

  In addition, by generating and displaying a print preview image of a file for which a print instruction has been received, even when printing is performed by a file storage operation, the print result can be confirmed before printing.

  Furthermore, if a folder corresponding to the status of the printing process is provided and the file is moved to a folder corresponding to the status of the printing process, by confirming in which folder the file instructed to be printed from the external device is located, The status of the printing process can be grasped.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
In the first embodiment, a file transferred by a file copy operation from an external device to a printing device is automatically printed (if it is a printable file). For this reason, in the first embodiment, in order to suppress erroneous printing, a procedure for displaying a print preview image and performing printing after confirmation by the user has been exemplified.

  However, there may be a case in which printing is performed without including such a confirmation procedure, or after the print preview image is confirmed and the execution of printing is permitted, it is desired to cancel the printing for some reason.

If the driver software is installed in the external device, it is possible to instruct to stop printing. However, in the method according to the first embodiment in which a file copy operation is interpreted as a print instruction, there is no mechanism for giving a stop instruction from an external apparatus to the printing apparatus.
This embodiment adds a mechanism for instructing to stop printing from an external device to the first embodiment. Therefore, the configurations of the printer 1 and the PC 2 may be the same as those in the first embodiment, and a description regarding the configurations is omitted.

(File structure of printer 1)
FIG. 6 is a diagram illustrating an example of a file configuration formed in an area (externally referable area) 4 that can be referred to from an external device in the storage device 106 included in the printer 1 of the present embodiment. This file structure is formed and managed by the file system 107.

  As shown in FIGS. 6A and 6B, in the present embodiment, a file for realizing print cancellation from an external device is added to the printer folder 301 shown in FIGS. 3A and 3B. Has been. Specifically, first and second print cancel files 308 and 309 are added to the printing folder 304, and a print cancel command file 306 is added immediately below the printer folder 301.

  Among these, the first print cancel file 308 is a file for an immediate cancel instruction corresponding to an instruction to immediately cancel the print process currently being executed.

  The second print cancel file 309 is a file for a next print cancel instruction corresponding to an instruction to cancel the print processing when the print processing of the file currently being printed ends.

Then, the access monitoring unit 110 monitors whether the first or second print cancellation file 308 or 309 has been deleted. Here, the deletion includes not only a case where the file is deleted on the file system 107 but also a case where the file is moved to a trash box provided by the OS operating on the PC 2. More simply, a state that does not exist in the printing folder 304 may be regarded as a deleted state.
When the deletion is detected, the control unit 109 performs a print cancel process on the assumption that an instruction corresponding to the deleted print cancel file has been input.

  The print cancel command file 306 is a command batch file that deletes the first and second print cancel files 308 and 309. Therefore, the file name of the print cancel command file 306 includes an extension “.BAT” indicating that it is a batch file.

  Therefore, the user can grasp that the print cancel command file 306 is a batch file. When an operation for executing the print cancel command file 306 by double-clicking the pointing device 204 of the PC 2 is performed, the first and second print cancel files 308 and 309 are deleted without opening the printing folder 304. Can do. When both the first and second print cancel files 308 and 309 are deleted, the control unit 109 gives priority to an instruction corresponding to the first print cancel file 308 whose stop timing is earlier, and immediately performs print processing. Discontinue. Accordingly, the print cancel command file 306 may delete only the first print cancel file 308.

  The print cancel command file 306 simplifies the procedure necessary for deleting the first and second print cancel files 308 and 309. Therefore, the print cancel command file 306 is not necessarily provided. .

  Note that the print cancel files 308 and 309 and the print cancel command file 306 can be generated at any stage until the print process is executed, but may be generated immediately before the print process is executed, for example. For example, in the procedure of the first embodiment illustrated in FIG. 5, after the print start instruction is input in step S <b> 509, the control unit 109 generates through the file system 107 before starting the print process in step S <b> 510. Can do.

FIG. 7 is a flowchart for explaining the operation related to the print cancellation process of the printer 1 according to this embodiment.
In step S701, the control unit 109 determines whether printing processing is being performed.

  If the printing process is being performed in step S701, the control unit 109 checks whether the access monitoring unit 110 detects the deletion of the first print cancellation file 308. Alternatively, the control unit 109 may check through the file system 107 whether the first printing cancellation file 308 exists in the printing folder 304.

  If the deletion of the first print cancel file 308 is detected or the absence of the current printing folder 304 is confirmed, the control unit 109 determines that immediate print cancellation has been instructed, and in step S704, the control unit 109 Instruct to stop printing. When the print cancellation process is completed, the control unit 109 advances the process to step S706.

  If the deletion of the first print cancellation file 308 is not detected in S702 or the existence in the printing folder 304 is confirmed, the control unit 109 advances the process to S703. In step S <b> 703, the control unit 109 checks whether the access monitoring unit 110 detects the deletion of the second print cancellation file 309. Alternatively, the control unit 109 may check whether the second printing cancellation file 309 exists in the printing folder 304 through the file system 107.

  When the deletion of the second print cancel file 309 is detected or the existence in the printing folder 304 is confirmed, it is determined that the next print cancel is instructed, and the control unit 109 sends a print end notification from the print unit 108. wait. When the printing unit 108 is notified of the end of printing being processed, even if there is a file waiting to be printed at that time, the printing process is stopped (S705), and the process proceeds to S706.

  If the deletion of the second print cancellation file 309 is not detected in S703 or the existence in the printing folder 304 is confirmed, the control unit 109 returns the process to S701.

  In step S706, the control unit 109 deletes the first and second print cancel files 308 and 309 and the print cancel command file 306, and ends the process. Also, the files remaining in the print waiting folder 303 and the printing folder 304 are deleted.

  As described above, according to the present embodiment, by preparing the file corresponding to the print cancel instruction in the externally referable area, it is possible to instruct the print process to be stopped by the file operation in the external apparatus. In addition, by preparing a file according to the print cancel mode, the user can instruct various types of cancel, such as immediate cancel or next print cancel. Also, by providing a command file for executing a file operation corresponding to the print cancel instruction, the user can more easily instruct the print cancel.

(Other embodiments)
In the above-described embodiment, a general-purpose computer has been described as an example of an external device. However, any device that supports a protocol that allows a printing apparatus to behave as a storage device can be used as an external device. As described above, such a protocol includes, for example, the USB protocol and the IEEE 1394 protocol. Therefore, any device that supports one of these protocols can be used as an external device. Specifically, a digital still camera or a digital video camera may be used.

  In the above embodiment, only the example in which the printing apparatus behaves as a USB mass storage class device has been described. However, the external device may support the IEEE 1394 protocol, and the printing device may behave as a storage device (such as a camera storage subunit) that can be read and written by an AV / C command.

  In the above-described embodiment, the configuration in which the access monitoring unit 110 detects that a file has actually been written has been described. However, the communication I / F 104 may detect a file access (read, write) request to an area that can be referred to from an external device, and handle the file for which a write request has been made as a file to be printed. Since the file write request includes information that can specify a write destination such as a folder, the communication I / F 104 can detect to which folder the file write is requested. Therefore, instead of access detection by the access monitoring unit 110, control similar to the above-described embodiment can be performed based on detection of an access request in the communication I / F 104. Thus, in the case of a configuration that detects a file write request, the access monitoring unit 110 can be omitted.

The above-described embodiment can also be realized in software by a computer (or CPU, MPU, etc.) included in the printing apparatus.
Therefore, the computer program itself supplied to the computer in order to implement the above-described embodiment by the computer also realizes the present invention. That is, the computer program itself for realizing the functions of the above-described embodiments is also one aspect of the present invention.
