This Nonprovisional application claims priority under 35 U.S.C. §119(a) on Patent Application No. 2009-194047 filed in Japan on Aug. 25, 2009, the entire contents of which are hereby incorporated by reference.
The present invention relates to a printing system for controlling a printing process performed by an image forming apparatus.
In printing using an image forming apparatus such as a printer, a copier or a facsimile apparatus, an information processing device connected to the image forming apparatus prepares a printing data item for forming an image and then issues a printing instruction to the image forming apparatus. In response to the printing instruction, the image forming apparatus performs printing according to settings related to the type of printing sheets to be used, a printing mode and the like which are designated by the user on a screen provided by a printer driver installed in the information processing device.
From the viewpoint of global environmental protection focused in recent years, there is an increasing demand for saving resources including printing media indicative of printing paper, printing toner and ink when printing is performed using image forming apparatuses. The functions of image forming apparatuses include those functions which can foster the resources saving by reducing the number of printing sheets to be used, such as a double-sided printing function for printing images on both sides of a printing sheet, and an aggregate printing function for printing a plurality of images on one printing sheet by scaling the images down. An image forming apparatus of the type having a color printing function can reduce the amount of consumption of coloring material, such as color ink and color toner, by printing a color image data item of less importance as an achromatic image, thereby making it possible to save resources.
In recent offices, an unspecified number of users connected to a network use image forming apparatuses connected to the network. These image forming apparatuses are managed by a specific manager. However, it is difficult for the manager to check the state of use on a user-by-user basis and urge each user to save resources as intended by the manager.
In view of this difficulty, an apparatus is disclosed which is configured such that when an image forming condition preset on the image forming apparatus side is different from an image forming condition transmitted from the information processing device, the image forming apparatus compares the two image forming conditions to each other, transmits a message corresponding to an inconsistent condition to the information processing device, and automatically informs the user of an image forming condition recommended by the image forming apparatus, thereby making it possible to urge the user to save resources as intended by the manager (see Japanese Patent Laid-Open Publication No. 2005-217878 for example).
The apparatus disclosed in Japanese Patent Laid-Open Publication No. 2005-217878 involves a problem that a user who uses printing data items unsuited for printing using a resources saving function is imparted with a sensation of troublesomeness because such a user is informed of a recommended condition every time the user gives a printing instruction.
In view of the foregoing problem, a feature of the present invention is to provide a printing system which is capable of urging users to save resources without imparting a sensation of troublesomeness to a user who uses printing data items unsuited for printing using the resources saving function.
A printing system according to the present invention has a plurality of ECO modes each provided for printing with a reduced amount of usage of at least one of printing media indicative of printing sheet, printing toner and ink. The “ECO modes” are ecological modes indicative of printing sheet saving modes, including N-up printing (N is an integer of not less than 2) and double-sided printing for example, and coloring material saving modes, including a mode for switching color printing to achromatic printing. The “N-up printing” is a mode for printing data in an amount of N pages on one side of a printing sheet.
The printing system according to the present invention comprises a display section, a storage section, a determination section, and a control section. The display section is capable of displaying an ECO mode recommending screen which recommends the plurality of ECO modes for selection. The storage section is configured to store therein a characteristic of a printing data item unsuited for ECO mode printing. The determination section is configured to determine whether or not a printing data item is suited for the ECO mode printing based on information stored in the storage section. The control section is configured to control the printing system based on a result of determination made by the determination section. The control section causes the display section to display the ECO mode recommending screen in response to a determination made by the determination section that the printing data item is suited for the ECO mode printing and then starts a printing process in response to a printing instruction given by a user, while, in response to a determination made by the determination section that the printing data item is unsuited for the ECO mode printing, starting the printing process without the display section displaying the ECO mode recommending screen.
The foregoing and other features and attendant advantages of the present invention will become more apparent from the reading of the following detailed description of the invention in conjunction with the accompanying drawings.
Hereinafter, a printing system according to an embodiment of the present invention will be described in detail with reference to the drawings.
As shown in
The printer 10 includes a sheet feeding section 11 and an image forming section 12. The printer 10 feeds a printing sheet, such as a plain paper sheet or a developing paper sheet, from the sheet feeding section 11 to the image forming section 12 and then performs printing based on a printing data item at the image forming section 12 to form a color or achromatic image on the printing sheet. For instance, the printer 10 is a multi-functional apparatus configured to perform electrophotographic printing. The printer 10 has a plurality of ECO modes each provided for printing with a reduced amount of usage of at least one of printing media indicative of printing sheet, printing toner and ink. The “ECO modes” are printing modes for N-up printing (N is an integer of not less than 2) and achromatic printing for example. The “N-up printing” is printing of data in an amount of N pages on one side of a printing sheet. The type of printing to be performed by the printer 10 may be selected from a plurality of types irrespective of the electrophotographic printing, ink jet printing or other type of printing.
The information processing device 20, which is a personal computer for example, includes a main body 21, a display 22, a keyboard 23, and a mouse 24. The display 22 is equivalent to the display section defined by the present invention. The main body includes a control section 211, a storage section 212, a program storage section 213, a determination section 214, and a management section 215.
The control section 211 is connected to the display 22, keyboard 23 and mouse 24. The printer 10 is connected to the control section 211 either via a network or directly.
The storage section 212 is configured to store therein a characteristic of a printing data item unsuited for ECO mode printing. The characteristic of a printing data item unsuited for ECO mode printing indicates, for example, a watermark or a stamp as seen in
The determination section 214 is configured to determine whether or not a printing data item is suited for ECO mode printing in response to a. printing instruction given to print that printing data item. The determination section 214 searches the printing data item for a specified key word stored in the storage section 212 to determine whether or not the specified key work is present in the printing data item, thereby determining whether or not the printing data item is suited for ECO mode printing.
The management section 215 is configured to manage an ECO contribution degree indicative of a rate of reduction in the amount of usage of printing media at a printing occasion on a user-by-user basis. The management section 215 increases the ECO contribution degree when a printing data item is printed by ECO mode printing in response to a printing instruction to print that printing data item while decreasing the ECO contribution degree when the printing data item is printed by normal printing (1-up single-sided color printing).
The program storage section 213 has installed therein an application program 213A for data preparation, a printer driver 213B for controlling the operation of the printer 10 during printing, and a printing control program 213C, together with an operating system.
The control section 211 operates according to the programs stored in the program storage section 213. The control section 211 prepares image data containing document data based on operation data on the keyboard 23 and the mouse 24 during execution of the application program 213A for data preparation stored in the program storage section 213. The image data thus prepared is converted to display data and then displayed on the display 22 and stored in the storage section 212.
The control section 211 prepares printing data from the image data stored in the storage section 212 based on the operation data on the keyboard 23 and the mouse 24 during execution of the printer driver 213B stored in the program storage section 213. The printing data thus prepared is outputted to the printer 10 via a non-illustrated interface.
When a request for printing is made by a user operating the keyboard 23 or the mouse 24 during execution of the application program 213A, the printer driver 213B starts up to cause the display 22 to display a print window 31 illustrated as an example in
As shown in
The print range zone 312 receives entry of designation of a print range in the image data prepared by an application program.
The copies zone 313 receives entry of a specified number of copies of image data in the print range set at the print range zone 312.
The scale up/down zone 314 shows particulars of settings established or calculation results with respect to the number of pages per sheet and a sheet size which form necessary information for determining a magnifying power for an image to be formed on the sheet.
The printer setting zone 311 presents the name of the printer 10 to be used for printing and receives entry of a change of printer when a plurality of printers are present that can be handled by the information processing device 20. The printer setting zone 311 is provided with a properties button 316 for checking the details of setting. When the user selects the properties button 316 by using the mouse 24, the display 22 displays a main setting window 32 shown as an example in
As shown in
In the main setting window 32 there are provided an OK button 328 and a cancel button 329. The OK button 328 receives entry of a definitive changed setting. The cancel button 329 receives entry of cancellation of a changed setting. The OK button 328 and the cancel button 329 are setting completion buttons which are operated when confirmation of a setting and a change of setting have been completed.
The control section 211 waits for entry of a printing instruction (in the case of NO in step S10). If the control section 211 determines that the entry of the printing instruction has been made (in the case of YES in step S10), the control section 211 causes the determination section 214 to determine whether or not a printing data item specified by the printing instruction is suited for ECO mode printing (step S20).
The control section 211 determines whether or not the printing data item of concern is provided with a watermark (step S21). If it is determined that the printing data item of concern is provided with the watermark (in the case of YES in step S21), the control section 211 causes the storage section 212 to store A=1 (step S22). If it is not determined that the printing data item of concern is provided with the watermark (in the case of NO in step S21), the control section 211 causes the storage section 212 to store A=0 (step S23).
Subsequently, the control section 211 determines whether or not the clause “The ECO recommending screen is not displayed when a watermark is present.” appearing on the ECO display setting screen 80 is checked (step S24). If it is determined that the clause is checked (in the case of YES in step S24), the control section 211 causes the storage section 212 to store B=1 (step S25). On the other hand, if it is not determined that the clause of concern is checked, the control section 211 causes the storage section 212 to store B=0 (step S26).
Subsequently, the control section 211 causes the determination section 214 to determine whether or not the printing data item of concern is suited for ECO mode printing (steps S27 to S29). Specifically, the determination section 214 determines whether or not the storage section 212 has stored A=1 and B=1 therein (step S27). If it is determined that the storage section 212 has stored A=1 and B=1 therein (in the case of YES in step S27), the determination section 214 determines that the printing data item of concern is unsuited for ECO mode printing (step S28). On the other hand, if it is not determined that the storage section 212 has stored A=1 and B=1 therein (in the case of NO in step S27), the determination section 214 determines that the printing data item of concern is suited for ECO mode printing (step S29).
Though the determination process in step S20 is directed to the exemplary process flow performed when the clause related to the watermark appearing on the ECO display setting screen 80 is checked, the determination process is not limited to the case where the clause related to the watermark is checked. A process flow similar to the process flow S21 to S29 is applicable to any other clause appearing on the ECO display setting screen 80. The details of the determination process in step S20 are similar to those of a determination process performed in any one of steps S110, S210, S310 and S510 to be described later.
If the control section 211 determines that the determination section 214 has determined in step S20 that the printing data item of concern is unsuited for ECO mode printing (in the case of NO in step S30), the process proceeds to step S60 without displaying an ECO mode recommending screen 40. On the other hand, if the control section 211 determines that the determination section 214 has determined in step S20 that the printing data item of concern is suited for ECO mode printing (in the case of YES in step S30), the control section 211 causes the display 22 to display the ECO mode recommending screen 40 as shown in
The ECO mode recommending screen 40 is a screen for urging the user to save resources. The ECO mode recommending screen 40 recommends the function of saving printing sheets and the function of saving color toner. The user can contribute to resources saving by selecting these functions. Further, the ECO mode recommending screen 40 presents data on the degree of contribution to ecology (ECO contribution degree) managed by the management section 215. The data on the ECO contribution degree allows the user to start being strongly conscious of resources saving.
After step S40, the control section 211 waits until the user enters a printing instruction (in the case of NO in step S50). If the control section 211 determines that the printing instruction has been entered (in the case of YES in step S50), the control section 211 starts printing the printing data item (step S60). Here, printing is performed under initial setting conditions when the print setting conditions have not been changed during displaying of the ECO mode recommending screen 40. On the other hand, when the print setting conditions have been changed during displaying of the ECO mode recommending screen 40, printing is performed under the changed print setting conditions. Thereafter, the control section 211 waits until the printing of the printing data item is completed (in the case of NO in step S70). If the control section 211 determines that the printing of the printing data item has been completed (in the case of YES in step S70), the control section 211 terminates the control process according to the present embodiment.
The present embodiment is configured to determine whether or not the printing data item specified by the printing instruction is suited for ECO mode printing and then determine whether or not to display the ECO mode recommending screen 40. For this reason, the present embodiment is capable of urging the user to save resources without imparting a sensation of troublesomeness to the user handling a printing data item unsuited for printing using the resources saving function.
The following description is directed to the determination criteria “The ECO mode recommending screen is not displayed if a watermark is present.” and “The ECO mode recommending screen is not displayed if a stamp is present.”. The “watermark”, as used herein, is meant by a printing character or the like which is not present in a printing data item having been just prepared by an application and which is added to that printing data item by a printer driver. Specific examples of such watermarks include letters, such as “secret”, “duplication strictly forbidden”, “absolutely confidential”, “important”, “circulation”, and “urgent”, and characters such as a company's logo. A printing data item provided with such a watermark or a stamp is often an official printing data item rather than a printing data item to be printed personally by the user and hence is unsuited for ECO mode printing in most cases. Therefore, by checking the check box for each of these determination criteria, the user can avoid feeling the troublesomeness that the ECO mode recommending screen 40 is undesirably displayed when printing a printing data item provided with the watermark or stamp.
The determination criterion “The ECO mode recommending screen is not displayed when a registered key word is present.” is described below. As shown in
The determination criterion “The ECO mode recommending screen is not displayed when printing a printing data item with a special setting.” is as follows. The “printing data item with a special setting” is meant to include, for example, a printing data item with a header or footer entered, a printing data item containing a logo, a printing data item to be printed on a printing sheet in a specified format, and a printing data item designating a specified sheet cassette. In most cases, these printing data items are unsuited for ECO mode printing (especially N-up printing). Therefore, by checking the check box for this determination criterion, the user can avoid feeling the troublesomeness that the ECO mode recommending screen 40 is undesirably displayed when printing a printing data item with a special setting. It is possible that the registration screen as shown in
The determination criterion “The ECO mode recommending screen is not displayed when printing a printing data item prepared by a specified application.” is as follows. Such specified applications include, for example, CAD, Photoshop, Paintshop, and Autosketch. In most cases, printing data items prepared by such applications are unsuited for ECO mode printing because the aesthetical appearance of resulting prints depends upon the image quality. Therefore, by checking the check box for this determination criterion, the user can avoid feeling the troublesomeness that the ECO mode recommending screen 40 is undesirably displayed when printing a printing data item prepared by such a specified application. It is possible that the registration screen as shown in
The determination criterion “The ECO mode recommending screen is not displayed when a ruled line is present.” is as follows. A method of extracting a ruled line present in a printing data item includes, for example, scanning the printing data item for a certain line in a primary scanning direction and then determining a length of contiguous black pixels that is not less than a threshold value, if it is detected, as a ruled line. Such a ruled line in a printing data item frequently forms part of a table. Because a printing data item containing a table is often a repetitive document or a document having a large number of numerals written small, almost all such cases are unsuited for ECO mode printing. Therefore, by checking the check box for this determination criterion, the user can avoid feeling the troublesomeness that the ECO mode recommending screen 40 is undesirably displayed when printing a printing data item having a ruled line.
The determination criterion “The above settings are applied to other printer drivers.” is as follows. Usually, the determination criteria described above are established for each printer driver. However, it is expected that a small number of users want to change the determination criteria for each printer driver. Therefore, by checking the check box for this determination criterion, the user can avoid feeling the troublesomeness that the determination criteria need to be established for each printer driver because the determination criteria established for one printer driver can be applied to other printer drivers.
For each of individual user accounts, the storage section 212 stores therein determination criteria checked on the ECO display setting screen 80, key words registered on the key word registration screen 90, and other registration items. Therefore, even in cases where a plurality of users share a single information processing device 20, the settings of concern can be customized on a user-by-user basis and, hence, the determination section 214 is allowed to make determination under settings suited for each user. Alternatively, it is possible to cause the storage section 212 to store therein settings established in a guest account to be shared by a plurality of users.
Description of control steps in this flowchart that are similar to the corresponding steps in the first embodiment will be omitted. According to the present embodiment, if the control section 211 determines that a printing data item specified by a printing instruction is suited for ECO mode printing (in the case of YES in step S120), an ECO mode recommending screen 50 as shown in
The ECO mode recommending screen 50 has a check box for preventing the ECO mode recommending screen from being displayed at the next-time printing occasion or its succeeding printing occasions. When a printing instruction is entered with this check box checked, the ECO mode recommending screen is not displayed at the next-time printing occasion or its succeeding printing occasions for a printing data item that is the same as or similar to the printing data item of concern.
Specifically, if the control section 211 determines that the check box on the ECO mode recommending screen 50 has been checked (in the case of YES in step S150) when a printing instruction is given, the control section 211 causes the storage section 212 to store therein a characteristic of the printing data item of concern (step S160). In printing a printing data item having the characteristic stored in the storage section 212 at the next-time printing occasion or its succeeding printing occasions, the determination section 214 determines that the printing data item of concern is unsuited for ECO mode printing.
Thus, even if a printing data item unsuited for ECO mode printing is erroneously determined to be suited for ECO mode printing, erroneous determination can be prevented thereafter by using the characteristic stored in the storage section 212 as a basis for determination in printing a printing data item that is the same as or similar to the printing data item for which the check box has been checked to prevent the ECO mode recommending screen 50 from being displayed at the next-time printing occasion or its succeeding printing occasions.
Description of control steps in this flowchart that are similar to the corresponding steps in the first embodiment will be omitted. According to the present embodiment, if the control section 211 determines that a printing data item specified by a printing instruction is unsuited for ECO mode printing (in the case of NO in step S220), a confirmation screen 60 as shown in
The confirmation screen 60 has options to display and not to display the ECO mode recommending screen. Therefore, even if the determination section 214 determines that the printing data item of concern is unsuited for ECO mode printing, the user himself or herself can again check whether or not the printing data item of concern is unsuited for ECO mode printing. If it is not determined by the control section 211 that the user wants to display the ECO mode recommending screen 40 (in the case of NO in step S260), the control section 211 starts a printing process immediately (step S270). On the other hand, if it is determined by the control section 211 that the user wants to display the ECO mode recommending screen 40 (in the case of YES in step S260), the control section 211 causes the ECO mode recommending screen 40 to be displayed (step S230).
Description of control steps in this flowchart that are similar to the corresponding steps in the third embodiment will be omitted. According to the present embodiment, if the control section 211 determines that a printing data item specified by a printing instruction is unsuited for ECO mode printing (in the case of NO in step S320), a confirmation screen 70 as shown in
The confirmation screen 70 has, in addition to the options to display and not to display the ECO mode recommending screen, a check box for preventing the confirmation screen 70 from being displayed at the next-time printing occasion or its succeeding printing occasions. When a printing instruction is entered with this check box checked, the confirmation screen 70 is not displayed at the next-time printing occasion or its succeeding printing occasions for a printing data item that is the same as or similar to the printing data item of concern.
Specifically, if the control section 211 determines that the check box on the confirmation screen 70 has been checked (in the case of YES in step S420), the control section 211 causes the storage section 212 to store therein a characteristic of the printing data item of concern as well as the setting established for preventing the confirmation screen 70 from being displayed in printing a printing data item having the characteristic stored in the storage section 212 at the next-time printing occasion or its succeeding printing occasions (step S430). Accordingly, the control section 211 fails to cause the display 22 to display the confirmation screen 70 in printing a printing data item having the characteristic stored in the storage section 212 which prevents the confirmation screen 70 from being displayed at the next-time printing occasion or its succeeding printing occasions.
Checking the check box on the confirmation screen 70 by the user means that the user wants normal printing of a corresponding printing data item. Therefore, the user can be relieved from the troublesomeness that the confirmation screen is displayed for every printing data item wanted to be printed normally.
Description of control steps in this flowchart that are similar to the corresponding control steps in the first embodiment will be omitted. According to the present embodiment, if it is determined by the control section 211 that a printing data item specified by a printing instruction is suited for ECO mode printing (in the case of YES in step S520), the management section 215 takes into account a rate of reduction in the amount of usage of printing media for the printing data item of concern in performing aggregate calculation of ECO contribution degrees (step S550). On the other hand, if it is determined by the control section 211 that the printing data item specified by the printing instruction is unsuited for ECO mode printing (in the case of NO in step S520), the printing process starts without the management section 215 taking into account a rate of reduction in the amount of usage of printing media for the printing data item of concern in performing aggregate calculation of ECO contribution degrees (step S560).
In managing the ECO contribution degrees on a user-by-user basis, if uniform management is done by which aggregate calculation of ECO contribution degrees is performed for all printing data items without taking the business circumstances of each user into consideration, users who often handle printing data items unsuited for ECO mode printing would be evaluated disadvantageously, thus resulting in unfair management.
By contrast, the present embodiment is capable of managing the ECO contribution degrees without imparting a sensation of unfairness to the users who often handle printing data items unsuited for ECO mode printing.
In any one of the first to fifth embodiments, it does not matter whether or not the printing system 100 forms a network. In cases where the printing system 100 does not form a network, the information processing device 20 is provided with the major components (i.e., control section 211, storage section 212, determination section 214, and management section 215) as shown in
In cases where the server 25 is provided with the major components, the storage section 212 of the server 25 stores therein the settings shown in
The foregoing embodiments are illustrative in all points and should not be construed to limit the present invention. The scope of the present invention is defined not by the foregoing embodiment but by the following claims. Further, the scope of the present invention is intended to include all modifications within the scopes of the claims and within the meanings and scopes of equivalents.
