1. Field of the Invention
The present invention relates to a printer and a print control method and more particularly relates to a method for controlling a printer at the time of creating a print profile.
2. Description of the Related Art
With the development of color output devices typified by printers and the like, it has become possible to print and output data from printers on various kinds of media (e.g., a sheet of paper or film). Recently, the number of media that are printable with printers is increasing, and in response to the demands of the market, many media manufacturers have begun to introduce a wide variety of media onto the market. Under such circumstances, printer drivers that can support a considerably wide variety of media from the beginning of installation are becoming popular; users are capable of freely replacing media with what they want to use and printing data thereon. When a user replaces a medium, the printer is controlled by a printer control parameter that is suitable for a replacement medium.
For media replacement, together with the operation of replacing a medium, a user also needs to provide a printer control parameter suitable for a replacement medium. If the printer control parameter provided is not suitable for the medium, the printer may not work properly. Thus, a method is known in which a user who replaced a medium must without fail change settings so that the printer control parameter is suitable for a replacement medium (see Japanese Patent Laid-Open No. 11-349150).
Since the number of media that are printable with printers is increasing and printer drivers that can support a considerably wide variety of media from the beginning of installation are becoming popular, users have become capable of freely replacing media with what they want to use and printing data thereon. However, there are still many new released media and many media that were not originally supported by any printer drivers in the world, in spite of the fact that using such media for printing is desired by many users.
In order to respond to such needs, creation systems have been devised, by which users are capable of creating color profiles that are to be added to printer drivers. Such creation systems enable users to add new media profiles (color profiles) created by special-purpose profile creation software to their driver software. A method that is popularly known for such later creation of additional media profiles is as follows: a user loads an arbitrary medium for which a profile is to be created, on a printer; then, patch image data that is necessary to create a profile is transferred from an external computer (hereinafter referred to as a PC) via special-purpose profile creation software to the printer, where the data is printed; and after a predetermined period of drying and subsequent color measurement, a profile is created using the obtained color measurement data.
In recent network environments, however, if a printer is connected to a network system, a user who is creating a media profile cannot always monitor the printer or have sole possession of the printer. Examples of such situations include the case where a printer is located some distance from a user; or the case where a user needs to leave a printer for a color measurement operation or any other operations. In such cases, the problem is that other users may replace the print medium without noticing that media-profile creation is being executed, because of the fact, as described above, that users are capable of selecting a wide variety of print media as well as freely replacing them at any time.
According to one aspect of the present invention, there is provided a printer including a print unit comprising: an execution unit that executes a profile creation mode of creating profile data that is used for color conversion processing performed on image data that is to be printed by the print unit; and a prohibition unit that prohibits print-media replacement or an operation of the printer, in response to execution of the profile creation mode.
According to the present invention, when a printer has been set to the profile creation mode, print-media replacement is prohibited during the course of profile creation. This brings about the effect of preventing such profile creation from ending in failure.
Further features of the present invention will become apparent from the following description of exemplary embodiments (with reference to the attached drawings).
First Embodiment
Now, a first embodiment according to the present invention will be described in detail with reference to the drawings.
Next, the first embodiment of the present invention will be described. A printer and an information processor according to the present invention and their operations will be described below with reference to
The operations of the printer will be described with reference to
The flow of data for profile creation will be described in further detail with reference to
When information about a print medium, for which a profile is to be created, has been received from the profile creation client PC 202, job IDs that uniquely define profile creation jobs are created so that later profile creation steps are managed using the job IDs. Print patch data and information about the print mode of the printer that are necessary for each step are transmitted to the profile creation client PC 202 in the form of a print setup file described in XML format. In the profile creation client PC 202, the profile creation software creates appropriate patch image data based on the XML print setup file received from the profile creation server 201.
The created patch image data is transferred to and printed by the profile creation printer 203. After a set period of time during which ink is dried and solidified, the printed patch image data is subjected to color measurement by a color measuring device. Color measurement data obtained from the color-measured patch image is transmitted to the profile creation server 201 via the profile creation software in the profile creation client PC 202. The profile creation server 201 manages such received color measurement data with job IDs and uses the data to create a media profile. Following the operation steps through some repetitions of the above-described operations eventually completes the creation of a media profile for a new medium.
Next, the procedure of processing will be described in further detail with reference to
Conventional printers generally offer free print-media replacement. However, if a print medium is replaced during the course of creating a print-media profile, proper color measurement data may not be obtained and the creation of the media profile may end in failure. In addition, if the creation of a media profile failed, it is difficult to determine at what point in time the profile creation has failed, so that the media-profile creation operation must be restarted from the very beginning. It is thus desirable for a user who is creating a media profile to prevent other users from heedlessly replacing the print medium placed on the profile creation printer 203.
A user who is creating a profile starts up a printer control panel in S302. The printer control panel serves as a control interface panel that controls printer operations: it receives instructions as to printer operations and enables printer control and a variety of settings. The user sets the printer to the profile creation mode via the printer control panel in S303. In S304, the printer that has been set to the profile creation mode operates so as to prevent heedless print-media replacement in the printer.
One concrete example of such a method for prohibiting print-media replacement is as follows: first, it is determined whether or not a printer is in profile creation mode; and if the printer is in profile creation mode and if other users who attempt to replace a print medium operate the printer control panel, a notification that the printer is in profile creation mode is given to the other users in order to prohibit heedless print-media replacement. Other examples that could be considered include a method in which a printer does not accept a print-media replacement operation via the control panel; and a method in which, if a printer has been set to the profile creation mode, a storage unit in which a print medium has been placed is mechanically locked. It is also possible to use all the above-described methods. The first embodiment of the present invention may use any method(s) as long as it is possible to prohibit other users from heedlessly replacing a print medium; the units and methods used therein are not intended to be limited. In either method, the status control unit 803 serves as a prohibition unit that exercises control in prohibiting print-media replacement or in prohibiting user operations via the control panel (operation unit). Note that, to release the printer from the profile creation mode, the printer control panel is started up in the same way as in setting up the profile creation mode so that the printer can be released from the profile creation mode via the printer control panel.
As described above, in the first embodiment of the present invention, a user who creates a profile is able to set a printer to the profile creation mode via the printer control panel after placing on the printer a print medium for which the profile is created. This prevents easy print-media replacement, thus preventing the use of an unintended print medium in the media-profile creation operation.
Second Embodiment
Now, another exemplary embodiment according to the present invention will be described in detail with reference to the drawings.
Referring to
Next, the second embodiment of the present invention will be described, taking processing as a concrete example. The printer and the print control system according to the second embodiment of the present invention and their operations will be described below with reference to
Hence, in the second embodiment of the present invention, if the profile creation printer 203 has received print data in S401, it is determined in S402 whether or not a normal print operation is possible, that is, whether or not the printer is in profile creation mode. If the printer is not in profile creation mode, normal print processing is performed on the print data received by the printer in S403. If the printer is in profile creation mode (i.e., if a user has created the settings from S301 to S303 in
As described above, the second embodiment of the present invention has a normal-print prevention function of preventing other users from performing normal printing on a printer in which a user is creating a profile, thus preventing the waste of time, resources, and media.
Variations in Second Embodiment
In the operations described in
If the profile creation printer 203 has received print data in S401, processing is performed using the procedure described in
In the processing method in
As described above, the second embodiment of the present invention has a normal-print prevention function of preventing other users from performing normal printing on a printer in which a user is creating a profile, thus preventing the waste of time, resources, and media. Moreover, even if normal print data is transmitted suddenly from other users during the course of profile creation, it is possible to hold print data without the profile creation operation being affected.
Third Embodiment
Now, another exemplary embodiment according to the present invention will be described in detail with reference to the drawings.
Referring to
Next, the third embodiment of the present invention will be described, illustrating the contents of concrete processing. The printer and the print control system according to the third embodiment of the present invention and their operations will be described below with reference to
First, the case of implementing printer calibration is described. For the implementation of printer calibration, a user other than the user who is creating a profile starts up a printer control panel in S601. In S602, the implementation of printer calibration is selected via the started control panel. Prior to the implementation of printer calibration, it is determined in S603 whether or not the printer has been set to the profile creation mode. If the printer is not in profile creation mode, printer calibration is implemented and the process is ended in S604. If it has been determined in S603 that the printer is in profile creation mode, the user who attempted to implement printer calibration is notified in S605 that printer calibration is impossible due to the fact that the printer has been set by another user to the profile creation mode. Then, the user instruction to implement printer calibration is cancelled in S606. Through the above steps, it is possible to prevent other users from implementing printer calibration on a printer in which one user is creating a profile.
Next, the case of print-head replacement is described. A user starts up a printer control panel in S701. In S702, the implementation of print-head replacement is selected via the started control panel. Prior to the implementation of print-head replacement, it is determined in S703 whether or not the printer has been set to the profile creation mode. If the printer is not in profile creation mode, the user implements print-head replacement and the process is ended in S704. If it has been determined in S703 that the printer is in profile creation mode, the user who attempted to implement print-head replacement is notified in S705 that print-head replacement is impossible due to the fact that the printer has been set by other users to the profile creation mode. Thereafter, the user instruction to implement print-head replacement is cancelled in S706. Through the above steps, it is possible to prevent other users from implementing print-head replacement on a printer in which one user is creating a profile.
In the above-described third embodiment, users give instructions to implement printer calibration or print-head replacement via a printer control panel; however, the present invention is not limited thereto and any other units may be used to issue instructions to a printer.
Although the implementation of printer calibration and print-head replacement have been described by way of examples of the cases where the status of a printer may change, the present invention is not limited thereto; it is obvious that the present invention is effective in any other process that can cause a change in the printing status of a printer.
