Abstract

PURPOSE: A method for processing a computer printing instruction of an image printing system is provided to suppress unnecessary printing errors and a delay of an operation time by controlling a decision for printing in accordance with a paper size and the current mode of a printer after a user instructs a printing operation. CONSTITUTION: A user instructs for a printing through an input device(100). The inputted printing condition is read(200) with respect to instructed printing objected document. Status information as a paper size and the current mode of a printer etc. is obtained by demanding to a connected printer(300). It is judged whether the printer mode is a pause mode from the status information(400). If the printer mode is a pause mode, a message for preparing of a printer engine as a printable status is transmitted to the printer(500). It is judged whether a size of a paper mounted in the printer is identified with a size of a paper set as the printing condition(600). If a size of a paper mounted in the printer is not identified with a size of a paper set as the printing condition, it is asked whether the user wishes to change the printing condition(700). If the user wishes not to change the printing condition, the document is converted into a printing language and transmitted to the printer(800). If the user wishes to change the printing condition, a changed set printing condition is obtained(900).

Description

Computer Printing Instruction Processing Method of Image Printing System

The present invention relates to a computer image information printing instruction processing method of an image printing system, wherein in the case where the printing conditions between the paper size prepared in the connected printer and the paper size set for the document to be printed are inconsistent, the printing condition is selected by the user's selection. The present invention relates to a computer image information printing instruction processing method of an image printing system capable of undergoing a modification process to block unwanted printing.

An image printing system has a computer and a printer connected via mutual cables or networks.

In such an image printing system, when the print target document data stored in the computer is translated into a printer language and transmitted to the printer, the printer prints the image corresponding thereto on the loaded paper.

When the printer in charge of printing is an electrophotographic method, an image is formed by spraying a toner or a liquid ink in a solid developing material onto a photosensitive medium on which an electrostatic latent image is formed by exposure, and then making contact with the photosensitive medium. By feeding and passing the paper loaded in the paper cassette between the rotating rollers, a desired image can be printed.

In such an image printing system, a printer provides status information relating to whether a print job is available to a user computer connected by a cable or a network. Examples of status information provided to a user's computer in a conventional printer include a busy signal indicating that the capacity is full by data received in a data receiving buffer, an empty signal indicating that there is no paper, and printing. It's a fault signal that tells you that a paper jam or some other serious problem can't print anymore. In addition, it provides information on the paper size loaded in the paper cassette when the user computer requests it.

In the meantime, when a user instructs a user to instruct a user to print a document or graphic image, which has been prepared, using a set paper size, the computer first checks the state information provided by the printer, and then the printer Delivery of print data to the furnace was determined.

In this case, if the status information provided from the printer is an empty signal, a failure signal, or a busy signal that cannot be printed, the user should take appropriate measures to prepare the printer for printing without sending the print data to the printer. An error message was sent to the user through the display device. On the contrary, if the empty signal, the fault signal, and the busy signal, which cannot be printed, are not included in the status information, the printable document data converted to the printer language is sent to the printer after the determination process is made possible.

However, in the conventional printing data sending decision process, it is not adopted as a data sending decision judgment element as to whether the status information and the paper size set for the document at the time of the data sending decision are attached to the printer. Even when the printer does not satisfy the printing conditions set by the computer, print data is sent to the printer to cause an image to be printed on an undesired paper, or the printing conditions indicated by the computer inside the printer are compared with the prepared printing environment. If it does not match, if it is configured to suspend or stop the printing process, even though unwanted image printing can be avoided, it may cause unnecessary time consumption and power consumption due to unnecessary printer decision-making intervention. There is a problem.

On the other hand, with regard to the printer status information, when there is no print job request for a printer engine element that can be printed only when it is heated to a certain temperature, the idle mode that lowers the heating temperature or cuts off the power supply for power saving. If the printer is operating in (sleeping mode), the job preparation instruction is sent to the printer to warm up from the sleep mode to the ready mode for printing before the process of converting the original to the printer language. By not doing so, there is an inconvenience in that the time required for warming up is made after sending the print data from the computer to the printer, thereby shortening the print job delay time.

The present invention was devised to solve the above problems, and the matching of the paper size provided by the printer with the decision to convert the print data to the printer for the document to be printed after the instruction for printing to the computer by the user It is an object of the present invention to provide a computer image information printing instruction processing method of an image printing system that can suppress unnecessary printing errors and work time delays that a user does not want depending on whether or not it is in idle mode.

Hereinafter, a computer printing instruction processing method of an image printing system according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing an image printing system to which the present invention is applied.

Referring to the drawings, in the image printing system, the user computer 10 and the printer 20 are interconnected by a cable or a communication interface 30 via a network.

The user computer 10 has a central processing unit (CPU) 11, a ROM 12, a RAM 13, a storage device 15 connected by the bus 14, and an input. The device 16 has a monitor 17 which is an output device. The input device 16 includes a keyboard and a mouse.

The storage device 15 includes a printer driver 15a that controls printing conditions, such as paper size, number of copies, enlargement, and reduction, and processing for converting the original data into a printer language and sending the decision about the document to be printed. Is installed.

On the other hand, the printer 20 connected with the computer 10 by the communication interface 30 is provided with the printer controller 21, the printer engine 22, and the input panel 23. As shown in FIG.

The printer controller 21 receives the print data from the computer 10 through the communication interface 30 and provides the system 10 with the required status information to the computer 10 and the print job control of the printer engine 22. To control. Here, the status information includes the size information of the paper prepared in the paper feed cassette (not shown) and whether the operation mode of the printer engine 22 is a sleeping mode.

In the case of the wet electrophotographic method, the printer engine 22 ejects an optical latent unit for forming an electrostatic latent image on a photosensitive medium, and develops an image by spraying an electrostatic latent image formed on the photosensitive medium by spraying toner or liquid ink in a solid state. A developing device and a transfer device for transferring an image formed on the photosensitive medium to a sheet of paper fed thereto.

The input panel 23 is provided outside the main body so that a plurality of input keys are provided to select various printing functions provided by the printer 20, and a key input signal is output to the printer controller 21.

This image printing system will be described with reference to FIG. 2, which shows a flowchart of a computer printing instruction processing method according to the present invention in conjunction with FIG.

First, the user issues a printing instruction using the input device 16 (100). The printing instruction includes a process in which a user designates a file of a document or a graphic image stored in the created document or the storage device 15 as a document to be printed, and inputs printing conditions therefor.

In the next step 200, the input printing conditions for the indicated print job target document are read. Here, the printing conditions include the size of the print paper and the number of prints.

In step 300, the connected printer 20 is requested to obtain its status information. Here, the status information includes information on the paper size mounted on the printer 20 and whether the printer engine 22 is in the idle mode, or whether a print job is possible.

Then, it is first determined whether the printer 20 is in the idle mode from the state information provided from the printer 20 (400). If the printer is in the idle mode, the printer engine 22 is placed in a state where printing can be performed by proper power supply resume. In operation 500, a message indicating a warm-up to prepare is transmitted to the printer 20.

When the printer is not in the idle mode or after the warm-up instruction is finished, it is determined whether the paper size installed in the printer 20 matches the paper size set as the printing condition among the printer status information except for the idle mode determination for the printing condition set for the document to be printed. (600).

If the paper size mounted in the printer 20 does not satisfy the paper size in the set printing condition in step 600, the user is asked whether to change the printing condition set for the document to be printed (700). This query message and its selection menu are provided on the screen via the monitor 17.

When the user gives a response not to change the printing condition set for the designated print document, the print target document is converted into the printer language and sent to the printer 20 (800).

On the contrary, the user gives an answer to change the printing condition set for the original to be printed, and when the user changes and sets the printing condition for the original, the changed printing condition is acquired accordingly (900). For the set printing condition, the process goes back to step 600 comparing with the status information provided by the printer 20.

In the process of determining the printing instruction, the selection process (step 700) allows the user to select the maintenance of the printing conditions even if the printing environment and the printing conditions are inconsistent. Therefore, the content of the original document should be limited to the selected paper size only. If not, for example, the purpose of reading only the first printing or document content that is similar to the paper size set in the printer 20, and does not have to insist on the print request only with the paper size set as the printing conditions In the case of written documents, the additional time required for resetting printing conditions can be avoided.

As described above, according to the computer printing instruction processing method of the image printing system according to the present invention, when the printer is in the idle mode according to the printer status information, the print job delay time is shortened by the warm-up instruction prior to sending the print data. And the mismatch between the set paper size and the paper mounted in the printer has the effect of suppressing unnecessary printing error by going through any one of the process of conversion to the print data without changing or changing the printing conditions by the user selection.
