DETAILED DESCRIPTION OF THE EMBODIMENTS
Reference will now be made in detail to exemplary 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 while referring to the figures. In this regard, the present exemplary embodiments may have different forms and should not be construed as being limited to the descriptions set forth herein. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.
FIG. 1 is a conceptual diagram of a mobile-based printing environment to which a method of setting a printing option according to an exemplary embodiment of the present general inventive concept is applied. Referring to FIG. 1, a mobile device 100, an all-in-one device 10, and a cloud server 20 may be connected to each other over a wireless network and transmit and receive printing data and various types of commands required for printing therebetween. In addition, since the mobile device 100 and the all-in-one device 10 both support near field communication (NFC), Wi-Fi Direct, or the like, direct printing to print content stored in the mobile device 100 with the all-in-one device 10 is possible with only a simple NFC tagging operation.
In this mobile-based printing environment, a user may set a printing option in the mobile device 100. According to a method of setting a printing option according to an exemplary embodiment of the present general inventive concept, a printing option may be relatively easily and conveniently set by an intuitive touch input of the user through a graphic user interface (GUI) displayed on a screen of the mobile device 100. The method of setting a printing option through a touch input will now be described in detail with reference to the accompanying drawings.
FIGS. 2A to 2E illustrate processes of setting each option in the method of setting a printing option through a touch input, according to exemplary embodiments of the present general inventive concept.
FIG. 2A illustrates a process of setting an N-up printing option in the method of setting a printing option, according to an exemplary embodiment of the present general inventive concept. The N-up printing option indicates an option of printing the content of two or more pages on one sheet of printing paper. Referring to FIG. 2A, on a preview screen 200 of a mobile device, a virtual sheet of paper 210 that corresponds to a frame for printing is displayed, and first to fourth thumbnails 221 to 224 corresponding to content available for printing are displayed in a thumbnail display area 220. The content available for printing may include for example pictures, documents, or other information to be printed by an image forming device such as the all-in-one device 10 illustrated in FIG. 1.
Before describing in detail a touch input operation to set an option, a basic touch input operation will be described in brief.
A user may perform an operation, such as selecting, moving, rotating, or turning over, the virtual sheet of paper 210 and the first to fourth thumbnails 221 to 224 displayed on the preview screen 200. In detail, if a short touch input on any one of the first to fourth thumbnails 221 to 224 is received, the touched thumbnail 221, 222, 223, or 224 is selected. If a user's finger moves in a state of a long touch on a thumbnail 221, 222, 223, or 224 with the finger, the touched thumbnail 221, 222, 223, or 224 moves along the finger until the touch ends, and this operation is referred to as a “drag and drop” hereinafter. In addition, a front or rear surface of the virtual sheet of paper 210 may be switched by vertically or horizontally moving a finger to slide on the virtual sheet of paper 210, and if a finger moves in a state of touching one corner of the virtual sheet of paper 210, the virtual sheet of paper 210 may be rotated from a vertical direction to a horizontal direction or vice versa. These operations are illustrated in FIGS. 2A-E with the illustrations of a user's hand. A hand illustrated in dashed lines indicates a beginning of a touch input, for example the starting point of a drag and drop operation. A hand illustrated in solid lines indicates an end of a touch input, for example the end point of a drag and drop operation.
Referring back to FIG. 2A, according to view (a), if the first thumbnail 221 is dragged and dropped onto the virtual sheet of paper 210, content corresponding to the first thumbnail 221 is displayed on the virtual sheet of paper 210. According to view (b), in a state where the content corresponding to the first thumbnail 221 is displayed on the virtual sheet of paper 210, the second thumbnail 222 is dragged and dropped onto the virtual sheet of paper 210. As such, if two or more thumbnails are dragged and dropped onto the one virtual sheet of paper 210, the mobile device determines N-up printing, that is, printing multiple pages of content on one side of a single sheet of printing paper, and displays the content corresponding to the first thumbnail 221 and content corresponding to the second thumbnail 222 on the virtual sheet of paper 210 as illustrated in view (b) of FIG. 2A. In addition, a mask image indicating that an N-up printing option has been set overlaps with the first thumbnail 221 and the second thumbnail 222 in the thumbnail display area 220.
FIG. 2B illustrates a process of changing a printing order in the method of setting a printing option, according to an exemplary embodiment of the present general inventive concept. Referring to FIG. 2B, the first to third thumbnails 221 to 223 from among the first to fourth thumbnails 221 to 224 in the thumbnail display area 220 are selected to be printed. In this case, although the first to third thumbnails 221 to 223 are basically printed according to an arrangement order of the first to third thumbnails 221 to 223, the printing order may be changed through a simple touch input. If a slide touch input on the thumbnail display area 220 is received, the printing order may be changed according to a preset criterion. A slide touch input corresponds to a continuous touch while the user's finger or other touching object moves across the screen. In the exemplary embodiment illustrated in FIG. 2B, when the illustrated slide touch input is received while in an original state, a message 230 indicating that the printing order is changed to a reverse order is displayed. That is, the printing order is set in an order of the third thumbnail 223, the second thumbnail 222, and the first thumbnail 221.
It will be understood that the thumbnails may be rearranged differently when the slide touch input is made, according to the preset criterion. For example, if the slide input begins on a first thumbnail 221 and ends on another thumbnail, for example 223, the locations of those thumbnails 221 and 223 could be swapped while the other thumbnails are not moved. Alternatively, if the slide input begins on the first thumbnail 221, the location of the first thumbnail 221 could be moved to the end location of the slide input. Furthermore, when the printing order is changed in this fashion, the content displayed on the virtual sheet of paper 210 may be changed accordingly. For example, when content corresponding to the first thumbnail 221 is displayed on the virtual sheet of paper 210 and the printing order is changed to a reverse order, such that the third thumbnail 223 becomes first in the printing order, content corresponding to the third thumbnail 223 could be displayed on the virtual sheet of paper 210. Alternatively, the content displayed on the virtual sheet of paper 210 could be unchanged by rearranging the print order, depending on the particular exemplary embodiment of the present general inventive concept.
In a state where the printing order is changed to the reverse order, if a slide touch input on the thumbnail display area 220 is received again, the printing order may be changed to another preset printing order. For example, the printing order may be changed to an odd page order or an even page order. The printing order may be arbitrary and set by the user according to circumstances.
FIGS. 2C and 2D illustrate a process of setting a duplex printing option in the method of setting a printing option, according to an exemplary embodiment of the present general inventive concept. FIG. 2C illustrates long-edge duplex in which printing is performed by turning paper over with a long edge of the paper as an axis, and FIG. 2D illustrates short-edge duplex in which printing is performed by turning paper over with a short edge of the paper as an axis. “Duplex printing” is defined herein as performing printing on both sides of a sheet of printing paper.
Referring to FIG. 2C, in view (a), if the first thumbnail 221 is dragged and dropped onto the virtual sheet of paper 210, content corresponding to the first thumbnail 221 is displayed on the virtual sheet of paper 210. In view (b), if a horizontal slide touch input on the virtual sheet of paper 210 is received, the virtual sheet of paper 210 is turned over with a long edge as an axis. Accordingly, in view (c), a rear surface of the virtual sheet of paper 210 is displayed. In view (d), the second thumbnail 222 is dragged and dropped onto the rear surface of the virtual sheet of paper 210, and content corresponding to the second thumbnail 222 is displayed on the rear surface of the virtual sheet of paper 210. Thereafter, a mask image indicating duplex printing is displayed on the first and second thumbnails 221 and 222 in the thumbnail display area 220.
Referring to FIG. 2D, in view (a), if the first thumbnail 221 is dragged and dropped onto the virtual sheet of paper 210, content corresponding to the first thumbnail 221 is displayed on the virtual sheet of paper 210. In view (b), if a vertical slide touch input on the virtual sheet of paper 210 is received, the virtual sheet of paper 210 is turned over with a short edge as an axis. Accordingly, in view (c), a rear surface of the virtual sheet of paper 210 is displayed. In view (d), the second thumbnail 222 is dragged and dropped onto the rear surface of the virtual sheet of paper 210, and content corresponding to the second thumbnail 222 is displayed on the rear surface of the virtual sheet of paper 210. Thereafter, a mask image indicating duplex printing is displayed on the first and second thumbnails 221 and 222 in the thumbnail display area 220.
FIG. 2E illustrates a process of changing a printing direction in the method of setting a printing option, according to an exemplary embodiment of the present general inventive concept. Referring to FIG. 2E, in view (a), a touch input of rotating the virtual sheet of paper 210 is received. The user may rotate the virtual sheet of paper 210, thereby changing the orientation of the virtual sheet of paper 210, by rotating two fingers in a state where the user touches the virtual sheet of paper 210 with the two fingers at the same time. The virtual sheet of paper 210 rotated by the touch input is illustrated in view (b). In view (c), if the first thumbnail 221 is dragged and dropped onto the virtual sheet of paper 210, a printing direction is set as landscape, according to the landscape orientation of the virtual sheet of paper 210. Thereafter, a mask image indicating a landscape printing direction is displayed on the first thumbnail 221 in the thumbnail display area 220. As described above, a printing direction of portrait or landscape may be set by rotating a direction of the virtual sheet of paper 210, thereby changing the orientation of the virtual sheet of paper 210, before adding a thumbnail onto the virtual sheet of paper 210.
As described in the above exemplary embodiments, a printing option may be simply and intuitively set by manipulating the virtual sheet of paper 210, which is a frame of printing, and the first to fourth thumbnails 221 to 224, which correspond to content to be printed, on the preview screen 200 through a touch input.
According to another exemplary embodiment of the present general inventive concept, a more realistic and intuitive method of setting an option may be provided to a user by providing a preview as a 3D view.
FIGS. 3A to 3F illustrate processes of setting an option when the method of setting a printing option through a touch input is implemented as a 3D view, according to exemplary embodiments of the present general inventive concept. For the purposes of the exemplary embodiments of the present general inventive concept illustrated herein, “3D view” is illustrated as a perspective view of one or more virtual sheets of paper. Such a perspective view allows a user to view the thickness of the virtual sheets of paper and the relative order of the virtual sheets of paper relative to one another, as described below with reference to FIGS. 3A-3F.
Furthermore, as illustrated in FIGS. 3A-F, when content corresponding to one or more of the thumbnails 321-324 is displayed on a virtual sheet of paper 310, 311, 312, etc., the corresponding thumbnails may be illustrated as blank pages, to visually indicate which content is currently arranged on the virtual sheet of paper 310, 311, 312, etc.
FIG. 3A illustrates a process of performing standard printing on a 3D preview. A virtual sheet of paper 310 is displayed as a 3D view on a preview screen 300. First to fourth thumbnails 321 to 324 are displayed in a thumbnail display area 320. In view (a), if the first thumbnail 321 is dragged and dropped onto the virtual sheet of paper 310, content corresponding to the first thumbnail 321 is displayed on the virtual sheet of paper 310 as illustrated in view (b). In this case, basic simplex printing, meaning one page of content is printed on one side of a single page of printing paper, is performed for the content corresponding to the first thumbnail 321. FIG. 3A illustrates a 3D embodiment of the operations illustrated in view (a) of FIG. 2A.
FIG. 3B illustrates a process of setting an N-up printing option on a 3D preview, according to an exemplary embodiment of the present general inventive concept. In view (a), a touch input of dragging and dropping the first thumbnail 321 onto the virtual sheet of paper 310 is received, and the first thumbnail 321 is simultaneously rotated counterclockwise. A mobile device analyzes the touch input of rotating the first thumbnail 321 as N-up option setting and displays content corresponding to the first thumbnail 321 on a half of the virtual sheet of paper 310 as illustrated in view (b). In view (c), if the second thumbnail 322 is dragged and dropped onto the virtual sheet of paper 310 and rotated, content corresponding to the second thumbnail 322 is displayed on the other half of the virtual sheet of paper 310. FIG. 3B illustrates a 3D embodiment of the operations illustrated in view (b) of FIG. 2A.
FIG. 3C illustrates a process of setting a printing order on a 3D preview, according to an exemplary embodiment of the present general inventive concept. In view (a), if the first thumbnail 321 is dragged and dropped onto the virtual sheet of paper 310, content corresponding to the first thumbnail 321 is displayed on the virtual sheet of paper 310 as illustrated in view (b). Thereafter, a new virtual sheet of paper 311 is added, and if the third thumbnail 323 is dragged and dropped onto the added virtual sheet of paper 311, content corresponding to the third thumbnail 323 is displayed on the added virtual sheet of paper 311 as illustrated in view (c). Accordingly, a printing order is set so that the content corresponding to the third thumbnail 323 is printed after printing the content corresponding to the first thumbnail 321.
FIG. 3D illustrates a process of setting a duplex printing option on a 3D preview, according to an exemplary embodiment of the present general inventive concept. The first thumbnail 321 is dragged and dropped onto the virtual sheet of paper 310 in view (a), and the virtual sheet of paper 310 is turned over with a long edge as an axis in view (b). In view (c), the second thumbnail 322 is dragged and dropped onto a rear surface of the virtual sheet of paper 310, thereby setting the duplex printing option. The duplex printing may also be set by turning the virtual sheet of paper 310 over with a short edge as an axis and dragging and dropping a thumbnail onto the rear surface of the virtual sheet of paper 310. FIG. 3D illustrates a 3D embodiment of the operations illustrated in FIGS. 2C-D.
FIG. 3E illustrates a process of changing a printing direction on a 3D preview, according to an exemplary embodiment of the present general inventive concept. In view (a), if the user rotates the virtual sheet of paper 310 counterclockwise by about 90° in a state where the user touches one edge of the virtual sheet of paper 310 with a finger, the virtual sheet of paper 310 is rotated and displayed as illustrated in view (b). In this state, the first thumbnail 321 is dragged and dropped onto the virtual sheet of paper 310 as illustrated in view (c), thereby setting a printing direction as landscape. FIG. 3E illustrates a 3D embodiment of the operations illustrated in FIG. 2E.
FIG. 3F illustrates a process of setting the number of sheets of paper to be printed on a 3D preview, according to an exemplary embodiment of the present general inventive concept. In view (a), all of displayed three virtual sheets of paper 310, 311, and 312 may be selected by touching a vacant area 330a on the preview screen 300. In this state, if the user moves a finger to another vacant area 330b on the preview screen 300 in a state of touching the any one virtual sheet of paper 311 with the finger as illustrated in view (b), three new virtual sheets of paper 310a, 311a, and 312a copied from the selected three virtual sheets of paper 310, 311, and 312 are added as illustrated in view (c). As a result, each of the pieces of content corresponding to the first to third thumbnails 321 to 323 is printed on two sheets.
FIG. 4 is a block diagram of the mobile device 100 according to an exemplary embodiment of the present general inventive concept. Referring to FIG. 4, the mobile device 100 may include a user interface unit 110, a control unit 120, a communication unit 130, a printing option management unit 140, and a preview providing unit 150, wherein the printing option management unit 140 may include a printing option determining unit 141 and a printing option applying unit 142.
