    Printer's Power Save Mode Control
    The present invention relates to an apparatus for controlling a power saving mode of a printer, and more particularly, an apparatus for controlling a power saving mode of a printer to control setting and releasing of a power saving mode of a printer by operating a separate power saving mode setting / release switch mounted on the printer. It is about.
    Generally, a printer is a device for printing document or image data created by an application program in a computer. The printer receives the document or image data from the computer and executes a print job according to a program set in the firmware (Firm Ware).
    In particular, the printer employs a power saving mode to reduce power consumption when the standby state is maintained for a predetermined time or more. In a conventional printer, a method of setting or canceling a power saving mode is as follows.
    First, the power saving mode setting method will be described. As the user sets the power saving mode starting time, the printer controller compares the current time with the power saving mode starting time, and if the current time is the same as the power saving mode starting time, the engine controller. Control the controller to leave the minimum power to the engine and shut off the rest of the power.
    Next, the power saving mode canceling method will be described. When the user opens or closes the printer cover or receives image data to be printed from the computer, the printer controller controls the engine controller so that power is normally supplied to the engine.
    By the way, according to the conventional method for setting the power saving mode by the printer, the following problems occur.
    (1) In order for the printer to enter the power saving mode, the printer should wait until the start time of the power saving mode set by the user. Therefore, even if the printer is not used, unnecessary power is wasted until the power-up mode start time.
    (2) In order for the printer to switch from the power saving mode to the operation start mode, data must be transmitted from the computer or the user must open and close the cover of the printer. Therefore, the user has to wait from the time of printing to the warming up time, which is inconvenient.
    Accordingly, an object of the present invention is to solve the above problems, and an object of the present invention is to add a power saving mode setting / release key to a predetermined position of a printer which a user can operate, so that the user can arbitrarily control the power saving mode of the printer. To provide a power saving mode control device for a printer.
    1 is a schematic block diagram showing an apparatus for controlling a power saving mode of a printer according to the present invention;
    Figure 2 is a detailed view of the operation panel shown in FIG.
    3 is a flowchart illustrating the operation of the CPU shown in FIG. 1.

    Features of the present invention for achieving the above object, the parallel port for receiving the image data to be printed; A memory in which the image data, the program data, and various data transmitted through the parallel port are stored; A printer engine for printing image data stored in the memory; An engine controller controlling a driving state of the printer engine; An operation panel including a display window for displaying an operation state of the printer engine and a power saving mode setting / release key for setting and releasing the power saving mode of the printer engine; And when the power saving mode setting / release key in the operation panel is input, checks the current state of the printer engine, and controls the engine controller to cancel the power saving mode when the current state of the printer engine is the power saving mode setting state. And a central processing unit for controlling the engine controller to set the power saving mode when the current state of the printer engine is in the power saving mode release state.
    Preferably, the central processing unit displays any one of the setting or the release of the power saving mode selected by the user on the display window of the operation panel as the user operates the power saving mode setting / release key.
    Hereinafter, a preferred embodiment of a power saving mode control apparatus for a printer according to the present invention will be described in detail with reference to the accompanying drawings.
    1 shows a schematic block diagram of a printer applied to the present invention.
    The printer as shown in Fig. 1 has a central processing unit (CPU) 1 for a printer which generally controls each component in the printer according to a predetermined program, and a plurality of function keys so that a user can select various functions. An operation panel (OPE) 2 arranged in an array and having a display window for displaying an operation state of the printer; a memory 3 storing program data and image data and other various data created by an application program of a computer; A printer engine 4 for printing image data transmitted from a computer, an engine controller 5 for controlling a driving state of the printer engine 4 under the control of the central processing unit 1, and a computer. It is composed of a parallel port (6) connected to receive the image data created by the application of the computer.
    In addition, the operation panel 2, as shown in Figure 2, the display window 7 for displaying the operating state of the printer, a plurality of function keys for selecting various functions of the printer, and in particular, set the power saving mode And an operation unit 9 including a power saving mode setting / release key 8 that can be released.
    Here, the power saving mode setting / release key 8 may be set as a toggle method in which the power saving mode setting function and the power saving mode canceling function are alternately performed as the user operates the power saving mode setting / release key 8. The power saving mode setting key and the power saving mode cancel key can be configured separately. However, in the present invention, the above-described toggle method will be used for the convenience of understanding.
    Referring to Figure 3 with respect to the operation of the present invention having such a configuration as follows.
    When a document created in an application program of a computer is converted into image data and then transferred to the central processing unit 1 through the parallel port 6 of the printer, the central processing unit 1 transfers the transferred image data to the memory 3. Store sequentially. Subsequently, when the transfer operation of the image data from the computer is completed, the central processing unit 1 converts the image data stored in the memory 3 into an image in the form of a bit map and transmits it to the engine controller 5. The engine controller 5 drives the printer engine 4 and then transmits the image in the form of a bitmap to the printer engine 4. Accordingly, the image in the form of a bitmap is printed by the printer engine 4, and the user can check the document created in the application program through the output.
    At this time, the operating state of the printer engine 4 is transmitted to the engine controller 5, the engine controller 5 transmits the operation information of the printer engine 4 to the central processing unit (1). The central processing unit 1 displays operation information of the printer engine 4 transmitted from the engine controller 5 on the display window 7 of the operation panel 2.
    On the other hand, the central processing unit 1 checks the key input state of the operation panel 2 to determine whether the power saving mode setting / release key 8 has been input (S1), and the power saving mode setting / release key 8 If it is determined that the input, the current state of the printer engine 4 is checked (S2). Here, when the printer engine 4 is currently set to the power saving mode (S3), the central processing unit 1 releases the power saving mode of the printer engine 4 through the engine controller 5 (S4).
    If it is determined in step 3 (S3) that the printer engine 4 is not currently set to the power saving mode, the central processing unit 1 puts the printer engine 4 into the power saving mode through the engine controller 5. It is set (S5).
    Therefore, the printer engine 4 can be set to the power saving mode or released from the power saving mode at the time desired by the user.
    As a result, according to the power saving mode control apparatus of the printer according to the present invention, there are the following advantages.
    That is, by additionally installing a power saving mode on / off key for setting or canceling the power saving mode of the printer engine, the printer engine is immediately set to the power saving mode or the power saving mode as the user operates the power saving mode setting / release key. By releasing the power supply, a separate standby state is unnecessary, so that the power consumption can be reduced, and it is convenient because the user can use it immediately at the time of using the printer.
