1. Field of the General Inventive Concept
Apparatuses and methods consistent with the present general inventive concept relate to a method of controlling printing and a printing control apparatus thereof, and more particularly, to a method of controlling printing using a single universal printer driver for a plurality of image forming apparatuses which are operated in different printing languages and a printing control apparatus thereof.
2. Description of the Related Art
In general, in order to print a document written in an application program of a computer using an image forming apparatus such as a printer or a multi-function printer (MFP), the printing control apparatus such as a computer should be equipped with a printer driver provided by a manufacturer of the image forming apparatus to control printing function of the image forming apparatus.
Recently, a user is able to use a plurality of image forming apparatuses by connecting them to a terminal device via a local or a local area network (LAN), and control printing function of the plurality of image forming apparatuses using a single universal printer driver.
However, a conventional universal printer driver could not control printing function of all image forming apparatuses. Specifically, since the conventional universal printer driver supported only one printing language for a driver, it was not able to control printing function of other image forming apparatuses which were operated in other printing languages.
For instance, if the image forming apparatuses 20a and 20b are operated in a PS printing language, the image forming apparatus 20c is operated in a SPL printing language, and the image forming apparatus 20d is operated in a PCL printing language, a universal printer driver supporting only the PS printing language is able to perform printing jobs of the image forming apparatus 20a and 20b. If a user desires to perform printing jobs of the image forming apparatus 20c and the image forming apparatus 20d, the user has to additionally install a SPL driver or and PCL driver for each image forming apparatus, or a universal printer driver supporting the SPL printing language and the PCL printing language, and this causes inconvenience to the user.

Exemplary embodiments of the present general inventive concept will now be described in greater detail with reference to the accompanying drawings.
Reference will now be made in detail to the embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.
In the following description, the same drawing reference numerals are used for the same elements even in different drawings. The matters defined in the description, such as detailed construction and elements, are provided to assist in a comprehensive understanding of the present general inventive concept. Thus, it is apparent that the present general inventive concept can be carried out without those specifically defined matters. Also, well-known functions or constructions are not described in detail since they would obscure the present general inventive concept with unnecessary detail.
The user interface unit 110 may include a plurality of function keys with which a user may set up or select various functions supported by the printing control apparatus 100, and may display diverse information provided by the printing control apparatus. The user interface unit 110 may be configured as a device to realize input and output simultaneously such as a touch pad, or a device combining a mouse and a monitor.
The user interface unit 110 may display a representation of at least one image forming apparatus connectable to the printing control apparatus 100, and may receive a selection of at least one image forming apparatus from among the displayed image forming apparatuses. Specifically, the user interface unit 110 may generate a user interface (UI) which displays one or more representations of a plurality of image forming apparatuses currently connected to the printing control apparatus 100 in a list, pictorial, or other form. In this case, the user interface unit 110 may also display different printing languages supported by the connected image forming apparatuses, and may display each printing language supported by the connected image forming apparatuses distinctively. Accordingly, a user may select at least one of a plurality of image forming apparatuses to perform a printing job or an image forming apparatus to set as a default image forming apparatus via the displayed user interface window. Detailed description regarding the user interface window will be provided later.
The communication interface unit 120 can be wired or wirelessly connected to a plurality of image forming apparatuses 200, and may provide converted printing data with regard to a printing job to an image forming apparatus. Specifically, the communication interface unit 120 may be configured to connect the printing control apparatus 100 to an external apparatus, and may be formed as a parallel port, a universal serial bus (USB) port, a wireless module, etc.
In addition, the communication interface unit 120 may receive and analyze information regarding an image forming apparatus from each connected image forming apparatus. Specifically, the communication interface unit 120 may analyze information regarding an image forming apparatus such as the title, name, or identifier of an image forming apparatus, an available printing language, an address of the image forming apparatus and port information by communicating with each connected image forming apparatus. The communication interface unit 120 may inform the user how many image forming apparatuses are connected at one time and how many more connections are available at a given time. According to an exemplary embodiment of the present general inventive concept, the communication interface unit 120 may communicate with a connected image forming apparatus periodically and store information regarding each of the connected plurality of image forming apparatuses in the storage unit 130. The information regarding an image forming apparatus means information necessary for print settings including the type of image forming apparatus, a port, and an available printing language.
The storage unit 130 may store information regarding one or a plurality of image forming apparatuses received from the communication interface unit 120. The storage unit 130 may also temporarily store printing data generated from the universal printer driver unit 140 which will be explained later, and may pre-store a script to store information regarding one or more printing options supported by each model type of image forming apparatus, an available printing language, etc.
The universal printer driver unit 140 may include a plurality of printer drivers corresponding to a plurality of languages, and may perform printing jobs for a plurality of image forming apparatuses operated in different languages. Specifically, if a user wishes to print a document written in an application program, the universal printer driver unit 140 may generate printing data in a language which can be recognized in an image forming apparatus that a user wishes to use to perform the printing job. The universal printer driver 140 may include a search unit 141, a setting unit 142, and a driver unit 143.
The search unit 141 may search for at least one image forming apparatus 200 connectable to the printing control apparatus 100. Specifically, the search unit 141 may search for image forming apparatuses currently connected to the printing control apparatus 100 using the communication interface unit 120, and control the interface unit 110 so that the searched for image forming apparatuses are displayed in a list. In this case, the search unit 141 may control the user interface unit 110 so that the connected image forming apparatuses are arranged and displayed in at least an order of printing history and connection priority. For instance, the search unit 141 may arrange and display the connected image forming apparatuses according to printing history such as printing date, printing time, printing requester, department which requested printing, and printing type and printing priority including color, mono, fax, and printing quality.
The search unit 141 may also arrange and display the connected image forming apparatuses according to connection priority by determining which image forming apparatuses are busy or being queued by other printing control apparatuses to perform higher or lesser priority jobs. If a higher priority job is being queued at one image forming apparatus, then the search unit may search for another available image forming apparatus, or an image forming apparatus assigned a lower priority by the control unit. If no image forming apparatuses are available, the search unit can determine the estimated availability time for the next available image forming apparatus. If a lower priority job is being queued, the search unit may allow the image forming apparatus to pre-empt the lower priority print job, if the lower priority print job has not yet started.
If a user selects an image forming apparatus from among the displayed image forming apparatuses, the search unit 141 may search for information supported by the image forming apparatus regarding the selected image forming apparatus. If the information regarding the image forming apparatus selected by the user is searched for, the search unit 141 may control the user interface unit 110 so that the user may display a printing language supported by the selected image forming apparatus.
Specifically, since an image forming apparatus can support a plurality of printing languages, the search unit 141 may display printing languages supported by the image forming apparatus selected by a user, and one of the printing languages can be selected to print an image. If the image forming apparatus selected by the user supports only one printing language, an operation to display printing languages and select one of them may be omitted. Alternatively, a printing language may be selected automatically according to a predetermined order of setting printing languages. For instance, if a printing language is set to be selected in the order of PS printing language, PCL printing language, and XPS printing language, and the user selects an image forming apparatus which supports PS printing language and PCL printing language, PS printing language may be automatically selected.
The search unit 141 may search for information regarding an image forming apparatus before a user selects an image forming apparatus. For instance, the search unit 141 may search for a connected image forming apparatus via the communication interface unit 120 periodically, and pre-store information regarding a connected image forming apparatuses, including information regarding a printing language supported by each image forming apparatus, in the storage unit 130. Therefore, the search unit 141 may display via the display unit 110 at least one connectable image forming apparatus together with at least one printing language supported by the image forming apparatus, and may control the user interface unit 110 so that image forming apparatuses may be displayed by each printing language supported by each of the image forming apparatuses. Specifically, if information regarding a plurality of connected image forming apparatuses is pre-stored in the storage unit 130, the search unit 141 may display at least one connectable image forming apparatus along with at least one printing language supported by each image forming apparatus, and may control the user interface unit 110 so that image forming apparatuses may be displayed to correspond to the printing language supported by each of the image forming apparatuses. For instance, if an image forming apparatus (A) supports PS printing language and PCL printing language, the search unit 141 may control the user interface unit 110 so that the image forming apparatus (A) can be displayed distinctively, such as ‘PS printing language-image forming apparatus (A)’, and ‘PCL printing language-image forming apparatus (A)’.
The setting unit 142 may set the image forming apparatus selected by a user to be a printable image forming apparatus based on the searched printing language. Specifically, the setting unit 142 may change a driver and a port regarding printing environment information of the printing control apparatus 100 to correspond to the driver of the universal driver unit 140 and port of the image forming apparatus selected by the user based on information regarding a printing language supported by the selected image forming apparatus from among the information searched by the search unit 141.
The setting unit 142 may also set the image forming apparatus selected by the user to be a default image forming apparatus. Specifically, the setting unit 142 may add the image forming apparatus selected by the user to a printer queue, set the added image forming apparatus as a default image forming apparatus, and delete a previous default image forming apparatus from the printer queue. In such a case, the setting unit 142 may determine the title, name or description of the selected image forming apparatus using a pre-defined script for each model, and add the determined title to the printer queue as the title of the selected image forming apparatus. The default image forming apparatus may represent an image forming apparatus to perform a printing job when the user does not select a specific image forming apparatus. The printer queue may represent a group of printers registered in the OS environment of a printing control apparatus. For instance, if a printing control apparatus is operated in Window XP OS environment, the printer queue may be a group of printers present in a “Printer and Fax” selection screen or menu.
The order of operation of adding a selected image forming apparatus to a printer queue and an operation of deleting a previous default image forming apparatus from a printer queue may be changed. In addition, the process of setting the selected image forming apparatus as a default image forming apparatus may be performed automatically. In this case, a picture or a message indicating the change of a default image forming apparatus may be displayed for the user to allow the user to know which image forming apparatuses have been automatically selected to perform a print job.
The driver unit 143 can include a plurality of printer drivers corresponding to a plurality of printing languages. The driver unit 143 may generate printing data using a printer driver corresponding to a selected image forming apparatus. Specifically, the driver unit 143 can include a plurality of printer drivers such as a PS printer driver, a PCL 5 printer driver, PCL 6 printer driver, a SPL printer driver, and a XPS printer driver, and may generate printing data in a form recognizable in an image forming apparatus selected by a user, using a printer driver corresponding to a printer driver setting in a given printing environment. Alternatively, the driver unit 143 may generate printing data using a single driver that supports a plurality of printing languages such as PS, PCL 5, PCL 6, SPS, XPS and others.
Therefore, even if an image forming apparatus recognizing a new printing language is developed, a printer driver corresponding to the new printing language may be added to the driver unit 143, and the printing control apparatus 100 may perform a printing job for the image forming apparatus recognizing a new printing language. Alternatively, a new printing language may be added to the single driver that supports a plurality of printing languages. Accordingly, by adding a new driver or driver program to the universal printer driver 140 it can be easier to implement new development and new models.
The control unit 150 may control the performance of a printing job in a printing language corresponding to a selected image forming apparatus, using a universal printer driver 140. Specifically, if a user's command to perform a printing job is received, the control unit 150 may determine whether the printing job can be performed in the selected image forming apparatus. For example, the control unit 150 may determine whether the selected image forming apparatus supports the printing language generated by the driving unit. If it is determined that the printing job cannot be performed, the control unit 150 controls the search unit 141 to search for an image forming apparatus that supports the selected printing language, which can perform the printing job as described above. If the search unit 141 cannot find an image forming apparatus that uses a printing language supported by the printer driver 140, the control unit may prompt the user to add another driver, or query the user whether the user wants to search the internet for a compatible driver to install.
If it is determined that the selected image forming apparatus can perform the printing job, the control unit 150 may control the driver unit 143 to generate printing data in a printing language supported by the selected image forming apparatus. The control unit 150 may control the communication interface unit 120 so that the generated printing data is transmitted via a port corresponding to the selected image forming apparatus.
If a user's command to change an image forming apparatus is received, and a new image forming apparatus is connected to the printing control apparatus 100, and if a printing job cannot be performed in a previously-set default image forming apparatus, the control unit 150 may perform the following operations.
Specifically, if a user's command to change an image forming apparatus is received, the control unit 150 may receive selection of an image forming apparatus from among the image forming apparatuses connected to the printing control apparatus 100 via the user interface unit 110, and set the selected image forming apparatus to be a printable image forming apparatus.
If a new image forming apparatus is connected, the control unit 150 may display the new image forming apparatus for a user via the user interface unit 110, and set the new image forming apparatus to be a printable image forming apparatus.
If a printing job cannot be performed in a previously-set default image forming apparatus, the control unit 150 may display connectable image forming apparatuses for a user, receive selection of one of them, set the selected image forming apparatus to be a printable image forming apparatus, and perform the above-mentioned process so that the printing job can be executed in the selected image forming apparatus.
In this case, the selected image forming apparatus may become a new default image forming apparatus, and the control unit 150 may control the user interface unit 110 so that information regarding the new default image forming apparatus can be displayed.
Accordingly, the user may perform the printing job using a single universal printing driver without installing a separate driver for each printing language.
In the above exemplary embodiments, the printing control apparatus 100 of the present general inventive concept includes not only a personal computer but also a notebook computer, PDA, PMP, and a cellular phone.
Referring to
The available printer display area 310 can display a plurality of image forming apparatuses connected to a printing control apparatus 100 and display an image forming apparatus which is currently connected to the printing control apparatus 100. In the exemplary embodiment, ‘Printer 1’ supporting PS, SPL, and PCL 6 printing languages, ‘Printer 2’ supporting PCL 5 printing language, ‘Printer 3’ supporting PS printing language, and ‘Printer 4’ supporting SPL printing language are illustrated. The title of image forming apparatuses may be displayed according to the printing language that each of the image forming apparatuses support. For instance, ‘Printer 1’ which supports PS, SPL, and PCL 6 printing languages may be distinctively displayed such as ‘Printer 1(PS)’, ‘Printer 1(SPL)’, and ‘Printer 1(PCL 6).’
The selected printer identification area 320 and printing language display area 330 that display the image forming apparatus selected by a user may display the image forming apparatus selected by the user and the printing language supported by the selected image forming apparatus. Specifically, if the user selects ‘Printer 1’ from the available printer display area 310 to display a plurality of image forming apparatuses, a printer description area 350 that displays information regarding the selected image forming apparatus is displayed, and if the selected image forming apparatus supports a plurality of printing languages, a printing language receiving area 340 to receive selection of a printing language may be displayed. Accordingly, a user may easily check information regarding the selected image forming apparatus and select an image forming apparatus and a printing language for the image forming apparatus. In an embodiment of the present general inventive concept, the printing language receiving area 340 to receive selection of a printing language may or may not be displayed. Specifically, if there is a predetermined priority regarding a plurality of printing languages, a printing language may be selected automatically according to the priority.
In this way, a user may check the availability of a printable image forming apparatus and select an image forming apparatus from among the displayed image forming apparatuses.
Referring to
If one image forming apparatuses from among the displayed image forming apparatuses is selected, the selected image forming apparatus may be set as a printable image forming apparatus. Specifically, at least one printing language supported by the selected image forming apparatus may be searched (operation S830) to see if the driver 400 supports the printing language. One printing language from among the searched languages is set as a printing language, and the selected image forming apparatus may be registered as a printable image forming apparatus (operation S840). After operation 840, the selected image forming apparatus may be ready to generate printing data and transmit printing data, as further illustrated in
Information which has been searched regarding the image forming apparatus selected by a user may be displayed for the user. Specifically, information regarding at least one printing language supported by the image forming apparatus from among information searched regarding the image forming apparatus may be displayed for a user. At least one printing language from among the displayed printing languages is selected by the user, and a printer driver within the driver unit or the universal printer driver may be selected based on this information. In addition, the selected image forming apparatus may be set as a default image forming apparatus. Specifically, the image forming apparatus selected by the user may be added to a printer queue, the image forming apparatus added to the printer queue may be set as a default image forming apparatus, and the previous default image forming apparatus may be deleted from the printer queue, so that the image forming apparatus selected by the user can be set as a default image forming apparatus. In this case, the title, name, or description of the image forming apparatus added to the printer queue may be determined using a pre-defined script for each mode. After the default image forming apparatus is changed, a picture or a message informing the change of the default image forming apparatus may be displayed for the user.
Referring to
On the other hand, if a determination is made that the printing job can be performed in the image forming apparatus set as the default image forming apparatus, printing data may be generated using a printing language corresponding to the image forming apparatus selected by the user (operation S940). Specifically, printing data may be generated using a printer driver corresponding to a printing language of the selected image forming apparatus in the universal printer driver.
The generated printing data may be transmitted using a port corresponding to the selected image forming apparatus (operation S950). Specifically, the printing data which has been converted into a printing language corresponding to the selected image forming apparatus may be transmitted to the port corresponding to the selected image forming apparatus.
Accordingly, a user may perform a printing job using a universal printer driver without installing a separate driver for a plurality of image forming apparatuses operated in different languages, and thus user convenience is enhanced.
