Description

Image forming device capable of changing output form for stored document and method for controlling the same}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus and a control method thereof, and more particularly, to an image forming apparatus having a self output function such that a document with frequent output is stored in a storage medium and reprinted the document through a panel as necessary. And a control method thereof.

When an image forming apparatus such as a printer transmits print data from a personal computer (PC), the image forming apparatus receives the print data and performs printing. At this time, the user should perform a series of processes such as searching for a desired file on the PC, executing the file on the PC, and inputting a print command. However, it is very cumbersome to have to search for and print files on the host every time for print data such as frequently used paper forms.

In order to solve such a problem, a conventional image forming apparatus includes a storage medium, stores print data designated by a user in a storage device in the image forming apparatus, and prints / prints the print data using keys provided on the panel as necessary. It had its own output function so that it could be deleted.

1 is a flowchart illustrating the operation of a conventional image forming apparatus having its own output function. The image forming apparatus selects a print mode for printing / deleting print data stored in a recording medium by using a key provided in the panel (S10). The data name and size of the stored print jobs are determined. Number of sheets), etc. are displayed as a list on the display of the panel (S20). Then, after selecting one print job from the list through the selection key (S30), if the 'delete' command is input (S42), delete the selected job (S44), if the 'print' command is input (S40) ), A setting screen is displayed to set the number of prints of the selected job (S50), and printing is performed for the set number of prints (S60).

In the image forming apparatus as described above, when the output form for the print data is set and transmitted from the host (for example, duplex or simplex, paper type, face up, and out) Bin, etc.), print data is stored on the recording medium together with output form information set in the printer, or a bitmap image formed through emulation of the printer is stored on the recording medium. You can print.

However, in the conventional image forming apparatus as described above, only when the print data is stored on the recording medium, the printing is performed only by the output form initially set by the host, but the output form cannot be changed by the image forming apparatus itself.

That is, when the output form of the stored job was duplex and was set to plain paper, the image forming apparatus itself could not change the document to simplex or output the document in accordance with the paper type on the tray. If the user wants to change the output form of the document, the host must search for the desired document again, reset the output form, and enter a print command to change the output form. This does not solve the troublesome problem because the user must operate the host as in the prior art.

SUMMARY OF THE INVENTION An object of the present invention is to provide an image forming apparatus and a control method thereof capable of directly outputting an output form of a document stored in a storage medium mounted in an apparatus so as to solve the above problems.

You can print it out.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram schematically showing a printer according to an embodiment of the present invention. The image forming apparatus includes an input unit 10, a host interface 20, a memory 30, a display 40, a printing unit 50, and a control unit 60.

The input unit 10 includes a print mode switch key for switching to a print mode, a print command key delete command key, and selection keys for selecting a job selection and output form so as to perform printing on jobs stored in a memory from a user. do. Here, each key is not provided, and one key may be used as an input key of another command in the order of input.

The host interface 20 interfaces print data and information with the host 200 together with a printer driver installed in the host 200.

The memory 30 stores print data sent and designated to be stored in the printer from the host. At this time, the converted bitmap image of the print data is stored, and the output form information set in the print data is stored together. The memory may be a hard disk.

The display 40 displays various operation states of the printer. Then, the character and the setting screen are displayed in response to the key input of the input unit 10. That is, a setting screen for allowing a user to designate a simplex or duplex is displayed, and a setting screen for specifying a type of printing paper is displayed. Also, setting screens for designating another output form can be displayed. The display 40 typically uses an LCD and forms a panel with the input unit 10.

The printing unit 50 prints the print data converted into bitmaps on the printing paper under the control of the control unit 60. The printing paper may be loaded in different trays according to types, and different types of paper may be loaded in one tray. Then, printing paper is selectively supplied from the tray according to the control signal of the control unit 60. Further, under the control of the control unit 60, printing is performed on the feed sheet in a simplex or duplex.

The controller 60 controls the overall printer, and in particular, when a print mode is selected through the input unit, a list is displayed on the screen about jobs stored in the memory 30. When a job is selected and a print command is input, a setting screen is displayed on the display 40 to set the number of prints, and when the number of prints is specified, a setting screen for changing the output form of print data is set in the set order. To be displayed on the display 40 accordingly. Subsequently, when the output form is designated through the input unit 10, the printing unit 50 is controlled to print the designated number of print units by applying the designated output form.

3 is a flowchart illustrating the operation of the printer shown in FIG. First, when the print data is transmitted from the host 200 via a cable such as a parallel or a universal serial bus (USB), and the print data is transmitted, the printer receives the print data from the host interface 20 to control the controller 60. To pass on. Then, the control unit 60 analyzes the header information of the print data, performs image processing on the print data as a bitmap image, performs printing according to the analyzed information, and stores the image-processed print data in the memory 30. Store in

When the print mode is selected by the user through the input unit 10 provided in the panel while the print data is stored in the memory 30 as described above (S110), the control unit 60 briefly describes each of the jobs stored in the memory 30. Read and display the list on the display 40 (S120). Thereafter, when the user selects a job through the selection key of the input unit 10 (S130), and inputs a delete command for the selected job (S142), the selected job is deleted from the memory 30 (S144), and the selected job When a print command is input (S142), a print quantity setting screen is displayed on the display 40 so that the user can specify the number of prints. When the print quantity is selected (S150), the selected number of prints is stored and the selected Displays a selection window asking the user whether to change the job's default output format. In this case, when the user selects the intention of changing the output style through the input unit 10 (S160), the printing is performed on the printing paper through the printing unit 50 according to the initially set output form (S162). On the other hand, when the user transmits the intention to change the output form through the input unit 10, and displays the setting screen for the item that can change the output form sequentially on the display. Finally, when the designation of the output form is completed (S160), the printed form is printed on the printing paper through the printing unit 50 by applying the changed output form (S170).

In the above process, the items that can change the output form may be dpi, simplex / duplex, paper size, paper type, etc., depending on the type of printer. In addition, all items that do not affect the image of the stored job can be applied. However, when the number of items to change the output form is increased, the load increases, rather it may be cumbersome to print one document. Therefore, it is desirable to be able to change the designation of the number of copies, the selection of duplex / simplex (in a function-bearing printer), and the degree of paper type change.

As described above, the image forming apparatus of the present invention can change the output form of the stored document in the apparatus itself and output the various forms, thereby eliminating the inconvenience of having to reset the desired output form in the host.
