Printer and Apparatus for controlling outputting Printing data capable of preventing printing about page of data nonexisting}

The present invention relates to a printer, and more particularly, a page in which a document is recorded and a document is recorded among pages for a corresponding document selected to form an image when the image data generated through the document creation module is output to a paper to form an image. The present invention relates to a printer that prints and prints out a page in which a document is recorded.

In general, a facsimile machine, a printer, a copier, or a multifunction device that can implement a combination of these functions through a single device are all products manufactured based on a printing function, and thus, a printer is provided for this purpose.

Such a printer is provided with a paper cassette in which recording paper is loaded, and picks up and transports the paper loaded in the paper cassette, and forms an image using a toner on the paper to be transported through the image forming unit and discharges it. do.

The printing operation is described as an example of the printers as follows. When power is supplied to the printer, warm-up is performed for a predetermined time according to the characteristics of the device, and when warming-up is completed, an on-line mode for executing a print command is performed. Then, if there is no print command for a predetermined time in the ready mode, the standby mode is returned to the standby mode. When the print command is issued in the standby mode, printing is performed through a warm-up process. Here, the warm-up process performed when power is supplied to the printer or a print command is received in the standby mode refers to an operation of preheating by applying a predetermined voltage to each roller of the printer engine that is in charge of the actual printing job in the printer. .

Thereby, the toner is applied to the electrostatic latent image formed according to the print data received from the outside to form a visible image, and the visible image is transferred onto the printing paper. The toner transferred to the printing paper as a visible image is fixed to the printing paper while the printing paper passes through a roller to which high heat is applied.

1 is a flowchart illustrating a process of performing an image forming operation on conventional data. First, a print command is performed to a printer drive module such that printable data such as a document edited in a computer including a document drive module and a print drive module providing a print command to the printer is printed through the printer (S11). The printer drive transforms the data to be printed into a signal that can be recognized by the printer (S13). The printer drive transmits a print command for the modified data to the printer (S15). The printer receiving the print command performs a printing operation of printing the received data on the paper to be fed (S17).

On the other hand, when the print drive transmits a print command to the printer, the print drive transmits a print command for the corresponding page selected by the user to the printer regardless of whether data edited in the document editing module is recorded. Therefore, the printer prints and outputs all received pages regardless of whether data is recorded or not according to the received print command. Accordingly, the printer has a problem that all pages are output regardless of whether blank pages are included in the document to be printed.

Also, it is a poster function that enlarges one page document edited through the document editing module and divides it into several pages. When a print command is executed through the printer drive module, a blank page without a document may be included. There is a problem that degradation and waste of paper occur.

Accordingly, under the control of the controller 10, the high voltage providing unit 26 applies a predetermined voltage to each of the rollers 24a, 24b, 24c, 24d, 24e, and 24f of the engine unit 24. Here, the High Voltage Power Supply (HVPS) 26 typically has a charging voltage of -1.4 [kW] for the charging roller 24a, a transfer voltage of +2.0 [kW] for the transfer roller 24f, and development. A developing voltage of -300 [V] is applied to the roller 24d, and a supply voltage of -500 [V] is applied to the supply roller 24e.

Accordingly, the charging roller 24a charged by the high-voltage charging voltage rotates in engagement with the photosensitive drum 24b to uniformly charge the photosensitive member formed on the outer circumferential surface of the photosensitive drum 24b. At this time, the exposure apparatus 24c receives a control signal from the controller 10 to scan the shape light corresponding to the shape of the data input from the controller 10 to the photosensitive drum 24b. Accordingly, the exposure apparatus 24c emits image light corresponding to the received control signal to the photosensitive drum 24b while an internal laser diode (LD) (not shown) is turned on.

On the surface of the photosensitive drum 24b, an electrostatic latent image to be charged which is charged by the shape light emitted by the exposure apparatus 24c is formed. On the other hand, a potential difference is generated between the supply roller 24e to which the high voltage is applied from the high voltage providing unit 26 and the developing roller 24d to which a voltage having a level lower than that of the supply roller 24e is applied. Thus, the toner bearing the negative charge component is transferred from the supply roller 24e to the developing roller 2d4, and the toner supplied to the developing roller 24d is applied to an electrostatic latent image formed on the surface of the photosensitive drum 24b to produce a visible image. Form.

The transfer roller 24f provided with the high voltage from the high voltage providing unit 26 transfers the visible image formed by applying the toner to the electrostatic latent image on the surface of the photosensitive drum 24b to the printing paper conveyed by the guide roller 24h. The visible image transferred to the printing paper is fixed to the printing paper by the high heat and pressure of the fixing unit 24g, thereby completing the printing process.

First, the data receiving unit 76a determines whether a print command for the document edited through the document editing unit 74 and data to be printed are received (S41). If it is determined in step S41 that the print command and data have not been received, the print command control unit 76d maintains the standby mode for transmitting the print command and the corresponding data (S43).

If it is determined in S41 that the print command and data have been received, the determination unit 76b determines whether there is data recorded for each page with respect to the received data (S45). The print command controller 76d performs a skip operation on a page for which data is not recorded among the pages for the received data according to the determination of S45, and prints a print command for printing the page on which the data is recorded. In step S47, the print command sending unit 76d is controlled to transmit to the print command.

At this time, the print command controller 76d determines whether there is a storage command signal for storing skip information according to the skip operation of the print command controller 76d (S49). If it is determined in S49 that there is a storage command signal, the print command control unit 76d stores the skip information in the skip storage unit 76e. Meanwhile, storing the skip information in the skip storage unit 76e may be performed according to a user's selection, or may be automatically performed according to a skip operation of the print command controller 76d.

In addition, the print command controller 76d determines whether there is a display request signal for the skip information stored in the skip storage 76e (S53). If it is determined in S53 that there is a display request time for skip information, the print command controller 76d retrieves the skip information requested from the skip storage unit 76e and displays the skip information on the display device 60 so as to be displayed on the monitor 80.
