Description

The method of sorting job using duplex function and print system}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for classifying a print job using a duplex function. In particular, a plurality of jobs are performed by a plurality of users by outputting the last page or the first page in a face up manner using the duplex function. If so, it relates to a method for classifying a print job using a duplex function for each user to easily check the printed paper output.

Face up refers to a state in which the printed side faces upward, and face down refers to a state in which the printed side faces downward. In general, most printers set the face down method as the default method, so that the printed surface is output downward.

Most printers, such as offices and laboratories, share a wired or wireless network connection and have a duplex function. The duplex function refers to a function of printing on both sides of paper and outputting it.

Since printers used in offices or public places are used by a large number of users, it is necessary to distinguish print jobs of each user. In response to this request, a method for distinguishing print jobs of each user was introduced.

The conventional printing job classification method repeatedly uses a face up method and a face down method for each print job. That is, the first print job outputs the entire sheet of paper in a face-down manner, and the next print job outputs the entire sheet of paper in a face-up manner.

According to this method, the time that the paper is output in the face-up method is twice as long as the time when the paper is output in the face-down method.

For example, if user A outputs 100 sheets of printing paper, and user B outputs 100 sheets of printing paper, the user B's printing paper is output in a face-up manner, so it takes more than twice as much time to print.

In addition, there is a method of classifying each print job by outputting a paper direction differently for each print job (for example, a method of outputting in a slanted manner from a basic output direction). However, this method requires a separate additional device so that the direction of the paper is set differently from the default output direction, and there is a problem in that additional cost is required to implement this.

An object of the present invention devised to solve the above problems is to print and output the last page or the first page in a face-up manner, when a plurality of print jobs are performed by multiple users, each user prints The purpose of this paper is to provide a printing method and a printing system using the duplex function to easily check the paper.

According to an aspect of the present invention, there is provided a method of classifying a print job using a duplex function, the method including: receiving a print command including print information; After receiving the print information and checking the output information for each page, check mark the duplex item if it is one of the last output page and the first output page, and if it is for other output pages, duplex Marking the item with null data; And converting and storing the print data suitable for the emulation.

Also, receiving print data; After checking whether there are any pending print jobs based on the print data, control to output the entire document face down when there is a pending print job. And checking the page if the duplex item does not have a check-in mark, and outputting the page in a face-down manner if the duplex item has a check-in mark. desirable.

A printing system according to the present invention includes a host computer for transmitting a print command including print information; After receiving the print information and checking the output information for each page, check-mark the duplex item if it is one of the last output page or the first output page, and if it is for other output pages, duplex It is preferable to include a printer driver unit for displaying the item as null data and converting it into print data suitable for the corresponding emulation, and a storage unit for storing the print data.

Also, a printer interface for providing a communication interface between the host and the printer; Analyzes the output information of the print data, and generates and outputs a face up signal that controls the page to be output in the face-up manner when there is a pending print job and corresponds to one of the last output page and the first output page. In case of other output page, it generates face down signal that controls page to be output in the face down method, and prints the page in face up method in response to face up signal or in response to face up signal. It is preferable to further include a printing unit for printing in a face-down manner.

In addition, if there is no waiting print job, the control unit preferably controls to output the entire document in a face-down manner.

Hereinafter will be described in detail with respect to the printing job classification method and printing system according to the present invention with reference to the accompanying drawings illustrated.

1 is a block diagram showing an internal configuration of a printing system according to the present invention.

Referring to FIG. 1, the present printing system is largely divided into a host 10 and an image forming apparatus 100. The host 10 includes an input unit 15, a printer driver 20 installed therein, and a storage unit 30. The image forming apparatus 100 includes a printer interface 40, a control unit 50, and a printing unit 60.

The host computer 10 receives a user's print command through the input unit 15 (eg, a keypad) and transmits the print command to the printer driver unit 20 installed therein. The print command transmitted to the printer driver 20 through the input unit 15 includes print information.

The printer driver 20 converts the document into data suitable for the corresponding emulation according to the print command.

The storage unit 30 stores the data converted by the printer driver unit 20.

The printer interface 40 interfaces the host 10 and the image forming apparatus 100, and print data is received by the controller 50 of the image forming apparatus 100 through the printer interface 40.

The controller 50 receives and analyzes print data from the image forming apparatus 100. In particular, check if the next print job in the print information is waiting. If the next print job is waiting, check the duplex item for each page.

The controller 50 generates and outputs a face up signal so that a page having a check-in mark in the duplex item is output in a face up manner. In addition, a page without a check mark in a duplex item generates and outputs a face down signal to be output in a face down manner, which is a basic output form.

The duplex item is checked in the printer driver 20 of the host 10. At this time, the duplex item is checked only for the last page or the first page.

The printing unit 60 prints each page by a face up method or a face down method in response to any one of a face up signal and a face down signal of the controller 50.

2 is a flowchart provided to explain a printing job classification method using the duplex function according to the present invention.

1 and 2, a user designates the number of prints and issues a print command through an input unit 15 (eg, a keypad, etc.) of the host computer 10 (S120).

First, the printer driver 20 converts the document into data suitable for the corresponding emulation according to the print command.

In the data conversion process, the printer driver 20 checks output information of the print data. The output information includes duplex or simplex, paper type, face up, and number of prints.

The printer driver 20 checks the number of prints through the output information (S140). After confirming the number of prints, the printer driver 20 checks whether the corresponding page is the last page (S160).

 If the page is the last page, a check-in mark is placed on the duplex item (S180). In addition, if the corresponding page is not the last page, the duplex item is displayed as null data (S200).

For example, if the number of prints requested by the user is 20, the duplex items are displayed as null data from pages 1 to 19. Only the last page, 20 pages, is marked as check-in for the duplex item. It is also possible to implement the check-in mark on the duplex item only on the first page, not on the last page.

The print data converted for the corresponding emulation includes information about the duplex item, that is, whether the duplex item has a check-in mark. The print data is stored in the storage unit 30 (S220).

In general, the storage unit 30 may be embodied in RAM, but when the print data is large, it may be embodied as a separate hardware device.

The printer interface 40 interfaces the host 10 and the image forming apparatus 100 with the printer driver 20 installed in the host 10 (S160).

When print data stored in the storage unit 30 is transmitted through the printer interface 40, the image forming apparatus 100 receives the print data from the printer interface 40 and transmits the print data to the controller 50 (S240).

The controller 50 analyzes the output information set in the print data for each page to be printed and performs image processing on the print data as a bitmap image through emulation.

At this time, it is checked whether other print jobs other than the current print job are waiting among the output information (S260).

If no other print job exists, the print job is controlled to be output in a face-down manner which is a general output form by simplexing all the print jobs (S300).

If there are no other print jobs, there is no benefit to distinguish each print job. The face down method is a general method in which the printed surface is printed downward.

If another print job is pending besides the current print job, the following operation is performed. The controller 50 checks whether the check-in display is set in the duplex item among the output information for each page (S280).

If the check-in is not marked on the duplex item, the page is controlled to be output in a face-down manner (S300).

If the check-in is marked on the duplex item, the page is controlled to be output in a face-up manner (S320). The face up method refers to a method in which a printed surface is printed upward.

Since the output information transmitted from the host 10 will be checked in the duplex item only in the case of the last page, it is possible to output only the last page upside down. In addition, if only the first page of the host 10 has a check-in mark on the duplex item, only the first page may be inverted and output.

If a print end command is received from the host 10, the print job ends (S340).

3 is a view showing a state in which printing paper is output by this process. Referring to FIG. 3, since the last page or the first page is output inverted for each print job (1, 2, 3, 4), it is possible to easily distinguish each print job. Thus, when multiple print jobs are waiting, each user can easily find his or her output document.

According to the present invention configured as described above, when a print job is performed by a plurality of users, each user can easily check the document output by the user, thereby increasing the convenience of the user.

In addition, according to the present invention it is possible to distinguish the print job only by a simple coding operation, there is no need for an additional device, thereby there is an effect that does not require additional costs.

In addition, according to the present invention, the output form is not changed for each print job. Since only the output form of the last page or the first page is changed, the output time is shortened when the number of prints is large.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and the present invention is not limited to the specific embodiments of the present invention without departing from the spirit of the present invention as claimed in the claims. Anyone skilled in the art can make various modifications, as well as such modifications that fall within the scope of the claims.
