## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority under 35 USC 119 from Japanese Patent Application No. 2002-368199, the disclosure of which is incorporated by reference herein.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a printing device and, more particularly, to a printing device, which sends notification of its status.
2. Description of the Related Art
In many of today's offices, personal computers are connected to a network and to peripheral devices such as printers, which are shared by multiple computers through the network. In such a networked environment, it is often difficult for a user, including an administrator such as a system manager, to know the status of the peripheral device at any given time, because the user is not necessarily near the peripheral device at all times.
In order to solve the above-described problem, a printer that allows the user to assess the status of the printer, even when the user is not physically next to the printer itself, has been proposed. This printer notifies the user of errors, such as when the printer cover is open or when the printer is jammed, by sending a message to the user via e-mail or the like (see: JP-A No. 6-320845).
However, when a user other than the system manager changes the settings on the printer, either deliberately or unintentionally, the system manager is not notified of the changes. When the changes are the source of system trouble, the system manager must first surmise that a user has changed the settings, and then based on the current settings, speculate what kind of changes were made thereto. Accordingly, solving such problems requires a lot of experience and man-hours.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a first embodiment according to the present invention will be explained, referring to drawings.
As shown in FIG. 1, a printing device 10 according to the first embodiment comprises a display device 152, such as an LCD, which functions as a display component; an operation circuit 154, which has keys, buttons and the like and functions as an inputting component that is operated by selecting a menu item displayed on the display device 152, in order to refer to and change settings in the printing device 10; a communication circuit 156, which is connected to a network and functions as a notifying component for communicating with external devices such as an administrator terminal; a storage device 158, which acts as a recording component, in which the settings and the like are recorded; a control circuit 160, which is connected to the display device 152, the operation circuit 154, the communication circuit 156 and the storage device 158 through a bus and controls them by functioning as an access component and a determination component; and a print processing section 162, which executes print processing. An information changing component comprises the operation circuit 154, the storage device 158, and the control circuit 160.
Next, the operation of the first embodiment will be explained, while referring to FIG. 2.
The user operates the operation circuit 154 in the printing device 10, and a change setting screen is displayed on the display device 152 to start the processing in FIG. 2. At STEP 102, in accordance with instructions displayed on the change setting screen, the user inputs setting changes and a password by operating the operation circuit 154 of the printing device 10. At STEP 104, the inputted password is transmitted to the control circuit 160 and, if it is determined that the inputted password is right for changing the settings to the inputting settings, the settings are changed by the control circuit 160 at STEP 106 by recording the settings to be changed in the storage device 158.
At STEP 108, the control circuit 160 determines whether the administrator needs to be notified of changes to the settings based on notification-necessary settings that have been prerecorded in the storage device 158. When it has been determined that notification of the changes to the setting should be sent, the changed setting data is transmitted at STEP 110 via the communication circuit 156 to the administrator terminal, which has an address prerecorded in the storage device 158, and the processing is terminated.
Processing is terminated when the password entered at STEP 104 is determined to be incorrect, and when it is determined that the administrator does not need to be notified of the changed setting.
In other words, the printing device 10 is configured to send setting changes to a predetermined administrator terminal, hence, the administrator can easily know of setting changes made in the printing device 10.
Therefore, when the administrator encounters trouble in the printing device 10, the trouble can be dealt with by referring to the notification of the setting data sent to the administrator terminal. This reduces the time the administrator has to spend solving the problem, and eliminates the need for an experienced administrator who can, based on that experience, surmise the source of the trouble.
The following items are listed as changeable settings: for example, a setting for a network connection such as an IP (Internet Protocol) address; a setting for printing conditions such as the size of printing paper and a type of an ink color; and a setting for printing on a piece of special printing paper. Certain settings, when changed, can cause fatal errors to occur. This is especially true in cases where the IP address is erroneously changed and the printing device 10 is no longer recognized by the network, making printing impossible.
The terminal for the administrator may be a server or a client for the administrator, a PDA (personal digital assistant), a cellular telephone and the like. Notification at STEP 110 may be transmitted, for example, by e-mail or may be an MIB (Management Information Base). Moreover, a control signal, which controls the terminal for the administrator according to the characteristic thereof, for example, by which a specific sound is output from the terminal for the administrator and by which the terminal for the administrator is vibrated, may be transmitted.
Furthermore, when the setting is changed, it has been determined at STEP 108 in the embodiment whether the changed setting is required to be notified or not. But the invention is not limited to the above embodiment. For example, at STEP 102, at which requirement for change of the setting is input, that is, at which the setting is required to be changed, it may be determined, as executed at STEP 108, whether the setting is required to be notified or not, and the setting may be notified when it is determined that the setting is required to be notified.
Though, when the setting is changed, it has been determined at STEP 108 in the embodiment whether the setting is required to be notified or not, the invention is not limited to the above embodiment. When the setting is accessed, for example, when the setting is required to be referred to, or when referring to the setting is executed, it may be determined as executed at STEP 108 whether the setting is required to be notified or not, and the setting may be notified when it is determined that the setting is required to be notified.
Though input of requirement for change of a setting and a password has been configured to be executed through the operation circuit 154 in the printing device 10 at STEP 102 in the embodiment, the invention is not limited to the above embodiment. For example, the input may be executed through a personal computer connected to the printing device 10 through the network.
Next, the operation of a second embodiment will be explained while referring to FIG. 3. Since the configuration of the second embodiment is similar to that of the first embodiment, the explanation regarding the same will be omitted. Moreover, with regard to the operation, components similar to those previously described in the first embodiment are denoted by the same reference numbers as those in FIG. 2, and the explanation will be eliminated.
When a setting is changed at STEP 106, it is determined at STEP 109 in a control circuit 160, based on settings, which are required to be recorded and have been recorded in a storage device 158 in advance, whether the changed setting is required to be recorded in the storage device 158 or not. When it is determined that the changed setting is required to be recorded, information on the changed setting is recorded in the storage device 158 at STEP 112 and the information on the changed setting is displayed on a display device 152 at STEP 114.
That is, the user can easily find that the setting in a printing device 10 has been changed because the information on the changed setting is configured to be recorded in the storage device 158 of the printing device 10.
Therefore, when the user including an administrator finds any troubles in the printing device 10, the troubles can be eliminated, referring to the information on the settings which have been recorded in the storage device 158. Thereby, the labor, which the user is required to spend for eliminating the troubles, is reduced. Moreover, the user will not be required to have experience-base knowledge, which is necessary for supposing the causes of the troubles.
Furthermore, when the setting is executed, it has been determined at STEP 109 in the embodiment whether the changed setting is required to be recorded or not. But the invention is not limited to the above embodiment. For example, at STEP 102 at which requirement for change of the setting is input, that is, at which the setting is required to be changed, it may be determined, as executed at STEP 109, whether the setting is required to be recorded or not, and the setting may be recorded when it is determined that the content is required to be recorded.
Though, when the setting is changed, it has been determined at STEP 109 in the embodiment whether the changed content is required to be recorded or not, the invention is not limited to the above embodiment. For example, when the setting is required to be referred to or when referring to the setting is executed, it maybe determined as executed at STEP 109 whether the referred setting is required to be recorded or not, and the referred setting may be recorded when it is determined that the setting is required to be recorded.
In STEP 102 of the embodiment of the present invention, the changing of settings and the inputting of a password are performed on the operation circuit 154 of the printing device 10, however, the present invention is not limited to such a configuration only. For example, inputting may be executed through a personal computer connected to the printing device 10 via the network. Moreover, the information has been configured to be displayed on the display device 152 of the printing device 10 at STEP 114, however, the invention is not limited to the above embodiment. For example, the information may be displayed on a personal computer that is connected to the printing device 10 via the network.
It has been determined in the embodiment, as described in the first embodiment, whether the setting is required to be notified or not and, when it is determined that the setting is required to be notified, processing by which the setting is notified to a terminal for the administrator may be further executed.
Next, the operation of a third embodiment will be explained while referring to FIG. 4. Since the configuration of the third embodiment is similar to those of the first and the second embodiments, explanations of the same will be omitted. Furthermore, with regard to the operation, steps similar to those previously described with reference to the first and the second embodiments are denoted by the same reference numbers as those in FIGS. 2 and 3, and explanations regarding the same will be omitted.
The user operates an operation circuit 154 in the printing device 10 and a setting on a change setting screen to be recorded is displayed on a display device 152 in order to start the processing in FIG. 4. At STEP 101, the user inputs the setting changes that should be recorded in the printing device 10 according to an instruction on the change setting screen, by operating the operation circuit 154. The inputted setting changes, which are to be recorded, are recorded in a storage device 158.
It is determined at STEP 109, based on the settings, which are required to be recorded and have been changed and recorded in the storage device 158, whether the changed setting is required to be recorded in the storage device 158.
That is, an administrator can change a setting in the printing device 10, which the administrator can easily find to be changed, because the printing device 10 is configured to change a setting to be recorded.
Accordingly, the user including the administrator can find only information on access to a desired setting among pieces of information on respective access which has been given to settings in the printing device 10, referring to the information on the settings which have been recorded in the printing device 10. This reduces the time and energy a user must spend looking for setting information, and furthermore, it conserves the recording capacity of the storage device 158.
Furthermore, when a setting is changed, it has been determined at STEP 109 in the embodiment whether the changed setting is required to be recorded or not. But the invention is not limited to the above embodiment. For example, at STEP 102 at which requirement for change of the setting is input, that is, at which the setting is required to be changed, it may be determined at STEP 109 whether the setting is required to be recorded or not, and the setting may be recorded when it is determined that the content is required to be recorded.
Though, when a setting is changed, it has been determined at STEP 109 in the embodiment whether the changed content is required to be recorded or not, the invention is not limited to the above embodiment. For example, when referring to the setting is required, or when referring to the setting is executed, it may be determined at STEP 109 whether the referred setting is required to be recorded or not, and the referred setting may be recorded when it is determined that the setting is required to be recorded.
Though input of requirement for change of a setting and a password at STEP 102, and change, at STEP 101, of the setting to be recorded are executed through the operation circuit 154 of the printing device 10 in the embodiment, the invention is not limited to the above embodiment. For example, the input and the change may be executed through a personal computer connected to the printing device 10 through a network. Moreover, the information has been configured to be displayed on the display device 152 of the printing device 10 at STEP 114. But the invention is not limited to the above embodiment, and, for example, the information may be displayed on a personal computer connected to the printing device 10 through the network.
It may be determined in the third embodiment, as described in the first embodiment, whether a setting is required to be notified or not and, when it is determined that the setting is required to be notified, processing by which the setting is notified to the terminal for the administrator may be further executed. In such a case, the setting to be notified may be configured to be changed. Moreover, the change and the recording of the setting have been explained for simplified explanation as one series of processing associated with change processing of settings to be recorded. But the invention is not limited to the above embodiments.
