Description

  The present invention relates to a printer such as a label printer that loads setting data stored in a portable storage medium such as a memory card.

In printers that can perform initial setting of functions according to the application, they are conventionally stored in initial setting information stored in a memory in the printer main body when the power is turned on, and in an initial setting storage device such as a card or a cartridge. There is already known a technique for comparing different information and assigning the information to a memory if there is different information (see, for example, Patent Document 1).
JP-A-3-279

  However, in the prior art as described above, the initial setting information stored in the memory in the printer main body and the information stored in the initial setting storage device are individually compared to determine whether there is different information. Therefore, as the number of setting information items increases, a longer processing time is required for comparison, and a longer time is required from power-on to completion of printer startup.

  The present invention has been made based on such circumstances, and an object of the present invention is to provide a printer that can shorten the time required for startup even when setting data stored in a portable storage medium needs to be loaded. It is something to try.

The present invention provides a printer for printing operation according to the setting of the setting data, and setting data storage unit that stores setting data, and identification data storage unit for storing identification data of the printer, setting data stored in the setting data storage unit portable storage medium such as a memory card for storing a table holding the identification data of the updated configuration data and configuration data storage unit a printer configuration data has finished updating the updated setting data for updating the connection It is possible, and a medium access means for performing data specification inclusive to the connected serial included data read from憶媒body and those 該記憶媒body. When the power is turned on, it is determined whether or not a storage medium is connected to the medium access means. If it is determined that the storage medium is connected, whether or not the storage medium stores a table is determined. When it is determined that the storage medium stores the table, it is determined whether the identification data stored in the identification data storage unit is stored in the table. When it is determined that the identification data stored in the identification data storage unit is not stored in the table of the storage medium, the updated setting data stored in the storage medium is loaded into the setting data storage unit. When the loading is completed correctly, the identification data stored in the identification data storage unit is written into the table stored in the storage medium. Start when the identification data has been written to the table, it is determined that the identification data is stored in the table, it is determined that the storage medium does not store the table, or the storage medium is not connected Transition to processing.

  According to the present invention in which such a measure is taken, it is possible to provide a printer that can shorten the time required for startup even when setting data stored in a portable storage medium needs to be loaded.

The best mode for carrying out the present invention will be described below with reference to the drawings.
In this embodiment, the printer to which the present invention is applied is a label printer. A portable storage medium in which setting data is stored is a USB (Universal Serial Bus) memory.

  FIG. 1 is a perspective view showing an external configuration of a label printer according to the present embodiment. Reference numeral 10 in the figure denotes a label printer main body, and a display 11 with a touch panel and a keyboard 12 are provided on the label printer main body. The label printer body 10 includes a printer unit 13 (see FIG. 3) as a label printing mechanism. The label printed by the printer unit 13 is discharged from a label issuing port 14 formed on the front surface of the label printer main body 10.

  As shown in FIG. 2, the keyboard 12 has a part number key 22, an erase key 23, a confirmation key 24, an issue key 25, a cursor key, in addition to a numeric key 21 for placing numbers “0” to “9”. Various keys such as 26 and menu key 27 are arranged.

  FIG. 3 is a block diagram showing a control circuit configuration of the label printer. The label printer is equipped with a CPU (Central Processing Unit) 30 as a control unit main body. In addition, a ROM (Read Only Memory) 31 in which fixed data such as a program is stored in advance, a RAM (Random Access Memory) 32 in which various memory areas such as a print buffer in which label print data is developed, and label printing are provided. A flash memory 33 as a setting data storage unit for storing various setting data necessary for the network, a network card 34 for connecting the label printer to a local area network (LAN), and peripheral devices conforming to the USB standard are electrically connected. USB controller 35, key controller 36 that receives a key signal corresponding to an operation key from keyboard 12 and a key controller 36 that receives a signal corresponding to a screen touch position from touch panel sensor 11A of display 11 with a touch panel, touch panel The screen of the attached display 11 A display controller 37 for controlling the data display of the liquid crystal display 11B, a printer engine 38 for controlling the label printing operation of the printer unit 13, and signals from various sensors 15 such as a label edge sensor and a label end sensor are input. An O port 39 and the like are provided. The CPU 30, ROM 31, RAM 32, flash memory 33, network card 34, USB interface 35, key controller 36, display controller 37, printer engine 38, and I / O port 39 are connected via a bus line 40 such as an address bus or a data bus. It is connected.

  The USB interface 35 is detachably connectable to a USB memory (flash memory) that is a portable storage medium conforming to the USB standard, and reads data from the connected USB memory and transfers data to the USB memory. Functions as medium access means for writing.

  The network card 34 is called a LAN card, a LAN board, or the like, and a MAC (Media Access Control) address 41 that functions as a hardware-specific address for a network device is set in advance.

  The flash memory 33 stores various setting data files such as a product number file, a label format file, a message file, a key assignment file, and an option file, and the CPU 30 performs a label printing operation according to the settings of these setting data files. .

  The label printer having such a configuration saves the latest versions of the various setting data files in the USB memory 50 functioning as a setting data storage medium, and connects the USB memory 50 to the USB interface 35 as necessary. Various setting data files in the flash memory 33 are updated by loading various setting data files in the USB memory 50.

  That is, when the power of the label printer is turned on, the CPU 30 is configured to start up in accordance with the procedure shown in the flowchart of FIG.

  First, the CPU 30 initializes each part of the RAM 32, the network card 34, the USB interface 35, the key controller 36, the display controller 37, the printer engine 38, and the like as ST (step) 1.

  Next, the CPU 30 determines whether or not a USB memory is connected to the USB interface 35 in ST2. When the USB memory is not connected, the process proceeds to a normal startup process.

  On the other hand, if a USB memory is connected to the USB interface 35, the CPU 30 determines in ST3 whether the USB memory is a USB memory 50 that functions as a setting data storage medium. Here, in the USB memory 50 functioning as a setting data storage medium, as shown in FIG. 3, in addition to the latest version of various setting data files 51, an identification data table 52 for holding identification data unique to each printer. Is remembered. Therefore, the CPU 30 checks whether or not the USB memory connected to the USB interface 35 stores the identification data table 52. If the USB memory 50 stores the USB memory 50, the USB memory 50 functions as a setting data storage medium. (Medium presence / absence judging means).

  If it is determined in ST3 that the USB memory is not the USB memory 50 functioning as a setting data storage medium, the CPU 30 shifts to a normal startup process.

  On the other hand, if it is determined that the USB memory is the USB memory 50 that functions as the setting data storage medium, the CPU 30 reads the MAC address set in the network card 34 as ST4, and the first work area of the RAM 32 is read. Store in A. In ST5, the data stored in the identification data table 52 is read from the USB memory 50 and stored in the second work area B of the RAM 32. Then, in ST6, it is determined whether or not data matching the data (MAC address) in the first work area A is stored in the second work area B (identification data determination means). Here, if it has been stored, the routine proceeds to normal startup processing.

  On the other hand, when the data that matches the data in the first work area A is not stored in the second work area B, the CPU 30 sets the offset file set in the option file in the flash memory 33. Among the information, check the option information that sets whether to load the setting data automatically or manually.

As a result, if the option information is automatically set, the CPU 30 proceeds to the process of ST10.

  On the other hand, if the option information is manually set, the CPU 30 displays a message screen on the touch panel-equipped display 11 for allowing the user to select whether or not to load the setting data in ST8. And it waits for selection operation of whether to load as ST9 performed. Here, when a selection operation not to load is performed by a key operation of the keyboard 12 or a touch operation on the touch panel, the process proceeds to a normal startup process.

  On the other hand, if the selection to load is performed, the CPU 30 proceeds to the process of ST10.

  In ST10, various setting data files 51 stored in the USB memory 50 are read, loaded into the flash memory 33, and the setting data file at the time of power-on is updated to the setting data file 51 stored in the USB memory 50. Processing is performed (setting data loading means).

  Thereafter, the CPU 30 determines whether or not the loading of the setting data file 51 has been correctly completed in ST11. Here, if the loading is not completed correctly, an error is notified and this process is terminated.

  On the other hand, when the loading is correctly completed, the CPU 30 writes the data in the first work area A, that is, the MAC address stored in the network card 34 in the identification data table 52 of the USB memory 50 as ST12. (Identification data writing means).

  Thereafter, the process proceeds to normal startup processing.

  As described above, in the present embodiment, when various setting data files stored in the flash memory 33 of the label printer are updated, the USB memory 50 storing the latest version of the setting data file is used as the USB of the label printer. With the interface 35 connected, the power is turned on. If the option information is automatically set on condition that the MAC address preset in the network card 34 of the label printer is not held in the identification data table 52 in the USB memory 50. The various setting data files in the USB memory 50 are automatically loaded, and the various setting data files in the flash memory 33 are updated to the latest version. If the option information is set manually, a selection screen for loading / unloading setting data is displayed. If loading is selected, various setting data files in the USB memory 50 are stored. The load is executed. Then, after loading the various setting data files, the MAC address of the label printer is written in the identification data table 52 of the USB memory 50.

  Therefore, when the USB memory 50 in which the already loaded setting data file is stored is connected to the USB interface 35 and the power of the label printer is turned on, the MAC address of the label printer is the identification data table 52 of the USB memory 50. Thus, the same setting data file is not loaded twice.

  This is very effective for a user who uses a plurality of label printers of the same model. That is, even if the USB memory 50 in which the setting data file already loaded is stored is mistakenly connected to the USB interface 35 and the power of the label printer is turned on, the setting data file is not loaded and the normal startup is immediately performed. Since processing is started, there is no need for wasted time for startup. For this reason, the user can start up a large number of label printers by connecting the USB memory 50 to the USB interface 35 without being aware of whether or not the label printer has already been loaded, which is efficient.

  Moreover, according to the present embodiment, the various setting data files stored in the USB memory 50 and the setting data file stored in the flash memory 33 are checked for each file to check whether they are different. Since it is not necessary, the time required for loading can be shortened even if the number of setting data files is large compared to the conventional method that has been individually checked, which is efficient.

  The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.

  For example, in the above embodiment, the MAC address is written in the identification data table 52 of the USB memory 50 as the identification data unique to the label printer. However, the user assigns a unique ID to each of the plurality of label printers in advance, and the flash memory 33 Even if this ID is stored in the identification data table 52 of the USB memory 50, the same effects as those of the above-described embodiment can be obtained. Incidentally, since the MAC address is preset for the network card 34, according to the embodiment, there is an advantage that the user does not need to set a unique ID.

  In the above-described embodiment, the USB memory 50 is used as the portable storage medium. However, it goes without saying that the portable storage medium is not limited to this. The present invention is not limited to a label printer, but can be applied to all printers that perform printing operations in accordance with setting data settings.

  In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, the constituent elements over different embodiments may be combined.
