How to control printing on your printer {METHOD FOR CONTROLLING PRINT IN PRINTER}

The present invention relates to a printing control method of a printer, and more particularly, to a printer that can save paper by not performing a printing operation on a white line that continues a predetermined line or more among print data transmitted from a computer. A print control method.

Generally, a printer is an office device connected to a computer and outputs a result on paper. The printer receives a document or image data created or edited on the computer, converts it into a printing language suitable for the printing conditions, and prints ink or toner. It is a device that outputs to paper using colored dyes.

Recently, due to the complexity of the office environment and the increase of office equipment and personal computers that are essential for the office environment, the office environment has gradually changed to a networking environment, and the data of each personal computer is connected by connecting the personal computers in the office to one network. By sharing a printer that is shared or combined with a personal computer, office expenses and work efficiency are being maximized.

Such a printer cannot edit the print data transmitted from the computer, and how quickly and accurately print the print data transmitted from the computer is an important problem.

Here, an example will be described in which the user has more empty space than the data actually printed on the print data sent to the printer to print documents created by various application programs of the computer.

If a document to be printed by the user has more empty space, that is, white lines, without any data than the data to be printed, the printer prints it as it is, causing waste of printing paper. This waste of printing paper is more serious when the document printed by the printer is a document that is viewed once and discarded for single use that does not need to be stored.

In addition, if a user performs an editing operation to delete white lines that do not need to be printed from a computer application in order to reduce the waste of printing paper, the editing operation is difficult if the amount of pages containing such data is huge. And waste of time.

Accordingly, an object of the present invention is to solve such a problem, and an object of the present invention is to count whether a white line continues more than a certain line among print data transmitted from a computer in a printer, and delete a white line that continues beyond a certain line. There is provided a printing control method of a printer that can save printing paper by not performing.

<First Embodiment of the Present Invention>

As in Figure 1, the central processing unit 1 of the printer applied to the present invention controls the system as a whole. In particular, the control unit is configured to delete the white line that continues a predetermined line or more from the data stored in the memory 2 and to print the data in which the white line stored in the memory 2 is deleted in units of pages.

The memory 2 stores various control programs necessary for driving the system and data generated by executing the program and print data transmitted from the computer.

The data analyzer 3 analyzes whether the data detected in the line unit among the data stored in the memory 2 is a white line and inputs it to the central processing unit 1.

The line count unit 4 counts the number of white lines identified as white lines by the data analyzer 3 among the data stored in the memory 2.

The line comparison unit 5 compares whether the number of lines counted by the line count unit 4 exceeds a preset value.

The printer engine 6 performs a print job according to the print data stored in the memory 2 under the control of the central processing unit 1.

The operating panel (OPE) 7 has a plurality of keys, and inputs key data according to a predetermined key press to the central processing unit 1, and displays the system by the display data of the central processing unit 1. It includes a display window for displaying the operation status.

The input / output port 8 is a medium connecting the printer and the computer.

The operation of the present invention configured as described above will be described in detail with reference to the accompanying drawings.

Referring to FIG. 2, when a print command is received from a computer through the input / output port 8 (S201), the printer central processing apparatus 1 stores the print data transmitted from the computer in the memory 2 ( S202).

In addition, the central processing unit 1 checks from the computer whether a saving mode that does not print a white line that continues a predetermined line or more is selected (S203).

Here, we will look at how to set the economizer mode so that the printer does not print white lines that continue beyond a certain line on the computer.

As shown in FIG. 3, when a user selects a print command to transmit a document created by various application programs of a computer to a printer, the print manager, which is a program which displays various states related to a print job, can be directly controlled by the user. The predetermined form is displayed on the screen of the computer. The user selects a saving mode that does not print a white line that continues more than a predetermined line in a predetermined form displayed on the screen of the computer, and executes a print command.

As a result of the check, when the signal in which the economy mode is selected is input from the computer, the data analysis unit 3 sequentially detects the data stored in the memory 2 in units of lines (S204), and all of the detected units of lines are '0'. It is determined whether or not (S205). Here, white data in which no print data exists is defined as 0.

As a result of determination, if the detected line unit data is all zero, the line count unit 4 increments the count by one (S206). Here, the initial value of the count set in the line count unit 4 is zero.

When the value counted by the line count unit 4 is input to the central processing unit 1, the line comparison unit 5 compares whether the input count value exceeds a preset value under the control of the central processing unit 1. (S207).

As a result of the comparison, when the counted value exceeds the preset value, the CPU 1 deletes the counted line unit data from the memory 2 (S208) and initializes the count value of the line count unit 4. (S209).

That is, the data stored in the memory 2 is detected on a line-by-line basis, and the line count section 4 counts the number of white lines when the detected line-unit data is all white lines. If the value counted by the line counting unit 4 exceeds the preset value, the data corresponding to the counted line is deleted from the memory 2, so that no data is printed on the printing paper so that a blank space is formed. Will be deleted before printing.

When the count value of the line count unit 4 is initialized, the central processing unit 1 checks whether it is the end of one page (S210), and if it is the end of one page, controls the printer engine 6 to store it in the memory 2. A print job is performed on the data (S211). At this time, the data stored in the memory 2 is in a state where all of the white lines that continue over a predetermined line are deleted.

On the other hand, the central processing unit 1 in the step 205 (S205) of determining whether the data in the line unit is all zero in the data analysis unit 3, by spraying black data, that is, ink on the detected line unit data to print If there is data to be executed, the process branches to step 209 (S209) in which the count value of the line count unit 4 is initialized.

In addition, when the value counted by the line count unit 4 exceeds the preset value, in step 207 (S207), if the preset value is not exceeded, data stored in the memory 2 is sequentially detected in line units. Branching to step 204 (S204) is repeated.

In addition, in step 203 (S203) of checking whether the saving mode that does not print a white line that continues more than a predetermined line is selected from the computer, if the saving mode is not selected, a print job for printing data stored in the memory 2 is performed. (S211).

Therefore, printing paper can be saved by deleting the white line which continues more than a predetermined line before printing the data stored in the memory 2.

<Second embodiment of the present invention>

As shown in Figure 4, the central processing unit 10 of the printer applied to the present invention controls the system as a whole.

The memory 20 stores data and print data generated by executing various control programs and programs necessary for driving the system.

The line buffer unit 30 temporarily stores print data transmitted from a computer.

The data analyzer 40 analyzes whether the data stored in the line buffer unit 30 is a white line and inputs the data to the CPU 10.

The line count unit 50 counts the number of white lines identified as white lines by the data analyzer 40 among the data stored in the memory 20.

The line comparison unit 60 compares whether the number of lines counted by the line count unit 50 exceeds a preset value.

The printer engine 70 performs a print job according to the print data stored in the memory 20 under the control of the central processing unit 10.

An operating panel (OPE) 80 has a plurality of keys, and inputs key data according to a predetermined key press into the central processing unit 10, and displays the system by the display data of the central processing unit 10. It includes a display window for displaying the operation status.

The input / output port 90 is a medium connecting the printer and the computer.

The operation of the present invention configured as described above will be described in detail with reference to the accompanying drawings.

Referring to FIG. 5, when a print command is received from a computer through the input / output port 90 (S501), the printer central processing apparatus 10 stores the print data transmitted from the computer in the line buffer 30. (S502).

In addition, the central processing unit 10 checks from the computer whether a saving mode is selected that does not print a white line that continues a predetermined line or more (S503).

Here, we will look at how to set the economizer mode so that the printer does not print white lines that continue beyond a certain line on the computer.

As shown in FIG. 3, when a user selects a print command to transmit a document created by various application programs of a computer to a printer, the print manager, which is a program which displays various states related to a print job, can be directly controlled by the user. The predetermined form is displayed on the screen of the computer. The user selects a saving mode that does not print a white line that continues more than a predetermined line in a predetermined form displayed on the screen of the computer, and executes a print command.

As a result of the check, when a signal in which the economy mode is selected is input from the computer, the data analyzer 40 sequentially searches the line buffer 30 and determines whether all data stored in the line buffer 30 is '0' (S504). . Here, white data in which no print data exists is defined as 0.

As a result of determination, if the data stored in the line buffer 30 is all zero, the line count unit 50 increments the count by one (S505). Here, the initial value of the count set in the line count unit 50 is zero.

When the value counted by the line count unit 50 is input to the CPU 10, the CPU 10 checks whether data stored in the next line buffer 30 exists (S506).

As a result of the check, if the next data does not exist, the data of the line buffer 30 counted by the line count unit 50 is stored in the memory 20 (S507), and then the data stored in the line buffer 30 is retrieved. After the operation of deleting the white line is finished, and if the next data exists, the line comparison unit 60 compares whether the input count value exceeds a preset value under the control of the CPU 10 ( S508).

As a result of the comparison, if the counted value exceeds the preset value, the CPU 10 initializes the count value stored in the line count unit 50 (S509), and transmits the data transmitted from the computer to the line count unit 50. The overwrite is stored in the line buffer 30 counted at (S510).

The central processing unit 10 overwrites the data transmitted from the computer to the counted line buffer 30 and controls the data analyzer 40 to determine whether the data stored in the line buffer 30 are all '0'. Branching to step 504 (S504) is repeated.

On the other hand, in step 508 (S508) of comparing whether the count value input from the line comparator 60 exceeds a preset value, if the counted value does not exceed the preset value, all data stored in the line buffer 30 is stored. The process branches to step 504 (S504) to determine whether it is '0' and repeats the process.

In operation 504 (S504), the data analyzer 40 determines whether all of the data stored in the line buffer 30 is '0', and prints black data, that is, ink, from the data stored in the line buffer 30. If there is data for performing the operation, the CPU 10 stores the data of the line buffer 30 including the black data and the data of the line buffer 30 counted by the line count unit 50 in the memory 20. Save (S511).

After the data stored in the line buffer 30 is stored in the memory 20, the CPU 10 initializes the value counted by the line count unit 50 (S512) and is stored in the line buffer 30. It is determined whether the next data exists (S513).

If the next data is present, the method branches to step 504 (S504) to repeatedly determine whether the data stored in the line buffer 30 is all '0'. If the next data does not exist, the data stored in the line buffer 30 is repeated. End the search and delete the white line.

On the other hand, in step 503 (S503) of checking whether the saving mode that does not print a white line that continues for a predetermined line or more from the computer is selected, if the saving mode is not selected, data stored in the line buffer 30 is stored in the memory 20. A general operation of storing is performed (S514).

Here, the print data stored in the line buffer 30 and stored in the memory 20 are transmitted to the printer engine 70 in a predetermined unit, and the printer engine 70 performs a print job according to the transmitted print data. Of course.

Therefore, printing paper can be saved by deleting the white line which continues for a predetermined line or more in the line buffer before the print data transmitted from the computer is stored in the memory.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims below and equivalents thereof.

As described above, according to the printing control method of the printer according to the present invention, the printer counts whether the white line continues more than a certain line among the print data transmitted from the computer, and performs a print job by deleting the white line that continues more than the predetermined line. By not doing so, there is an advantage of saving printing paper.
