BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer having a manual paper cutter, an automatic paper cutter, etc. Paper transfer technology for

[0002]

2. Description of the Related Art Conventionally, when printing is completed on a printing paper of a printer in a desired format as a receipt, several lines of paper are fed to the paper cutter position, and the printing paper is cut by a manual paper cutter or an automatic paper cutter. It was issuing. Generally, the paper cutting position is above the print head.If the cutting is continued after printing, the position of the manual paper cutter or the auto paper cutter may overlap the final printing position, or There was a problem that it was cut at the previous part. As one means for solving this problem, there has been a method in which several lines of paper suitable for the mechanism of the model are fed by a control command. However, according to such a method, it is necessary to reset the number of lines to be fed for each model to be used, which is a big obstacle in developing application software for printers having different mechanisms.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of such drawbacks, and by transmitting a transfer control command for cutting a printing paper from a host computer to the printer before cutting the printing paper, It is intended to provide a user-friendly printing paper transfer and printing paper cutting method for a printer, which has extremely excellent operability regardless of differences between models.

[0004]

SUMMARY OF THE INVENTION According to the present invention, by sending a print paper transfer control command including a paper feed amount to a printer, a predetermined amount of print paper is fed from the final print position of the model to the paper cutter position. A printer having control means for performing the operation.

[0005]

According to the structure of the present invention, conventionally, the printing paper cutting position of the manual paper cutter or the automatic paper cutter overlaps with the final printing position or the final printing position unless the paper is fed by several lines after printing is completed. There was a problem that it was cut at a position earlier, but by sending the command of the present invention to the printer, the print paper is fed by the optimum amount,
The printing paper can be transferred from the final printing position to the paper cutter position, and it is possible to provide a user-friendly printer. Further, it is not necessary to feed the printing paper for each printer model, which is very effective in developing application software and is very useful in industry such that software resources can be effectively used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic view showing a print head and a paper feeding mechanism which are main components of the printer according to an embodiment of the printer of the present invention. 10 is a stepping motor which is a paper feed drive source. Reference numeral 11 denotes a print head, which prints desired characters or symbols by sequentially rotating the carriage stepping motor 15 from side to side via the belt 16. In order to make it easier to understand, the embodiment shows a state in which printing is performed when the print head 11 moves in the direction of arrow A. Reference numeral 12 is a printing platen, which is usually made of a hard material. Reference numeral 13 is a printing paper. Reference numeral 14 denotes a paper feed roller. When the print head 11 finishes printing a desired number of lines, the paper feed stepping motor 10 is driven to rotate the paper feed roller 14 to rotate the print paper 1.
3 is derived in the direction of arrow B for one line. Reference numeral 17 is a paper cutter--a manual paper cutter is shown as an example, but the same applies to an automatic paper cutter.

FIG. 2 is an explanatory diagram showing the construction of the print processing method of the printer of the present invention. 20 is an interface for inputting data, 21 is a CPU, and 22, 23, 24 are I / O.
O port, 25 is ROM, 26 is RAM, 29 is a printer mechanism unit, 28 is a motor driver that drives and controls a motor in the printer mechanism unit, 27 is a head driver that controls the print head, and 30 is a paper feed switch. Shows. The RAM 26 has an input buffer for storing print data as it is and a print buffer for converting the print data into dot data of the print head portion of the printer and storing the dot data. The CPU 21 controls the printer as a whole according to the program code stored in the ROM 25. In the ROM 25, in addition to the program code, a character generator that converts a character font into data is stored. Generally, the printer reads a specific code from the character string data input from the host computer from the interface 20, interprets these required commands, and performs the printing operation while controlling accordingly. The paper feed switch 30 is generally arranged on the surface of the printer body as a part of the operation panel when assembled as a finished product of the printer, and the signal of this switch is sent via the I / O 24 to the CPU 21. Entered in.

FIG. 3 is a schematic view for easily explaining the transfer method for cutting the printing paper of the printer according to the present invention. In FIG. 3, a state in which desired printing is completed by the print head 11 and the paper feed roller 14 and the paper feed auxiliary roller 41 are rotated to feed the paper to a position required for issuing a slip of the print paper is shown. There is. After that, paper cutter 17
To cut the printing paper.

FIG. 4 shows an embodiment in which a predetermined amount of paper is fed to cut the printing paper according to the present invention. In order to move the final print position to the position of the paper cutter 17, the paper is fed by the space D plus an arbitrary blank space in FIG. Therefore, in the conventional control method, it is necessary to carry out paper feeding of several lines suitable for each model to create the paper. Commands for printing and n line feed, eg ES
C + d + n command is sent, but in order to create the same space D and an arbitrary blank space, for example, in model A, paper feed is performed by setting a value of n = 10, and in model B, n = 15. There is no compatibility because the value of the predetermined amount n differs depending on each model, such as setting the value of
It was a command that was difficult for users to use.

In order to avoid this problem, I / I shown in FIG.
F20 print paper feed control command, for example ESC
Send + S command. The ESC + S command includes a function of executing paper feed of a predetermined amount of space D of the model and an arbitrary margin, and if explained by the above-mentioned paper feed command, n of ESC + d + n
It is no longer necessary for the user to set the value of for each model each time. The same command can be used in the A model and the B model, and compatibility between the models has been achieved. By transmitting this command, the printer interprets the command, rotates the paper feed roller 14 and the auxiliary roller 41, and feeds a predetermined amount of printing paper, and finally prints the printing paper 13 as shown in FIG. Position plus margins with paper cutter 17
The printing paper is cut after being conveyed to the position.

FIG. 5 is a flow chart of the transfer control command in the present invention. In 101, there are two types of transfer control commands received by the printer.
2 ESC + d + n and 105 ESC +
S is applicable. As described above, the command 102 is issued by the user from the host computer to the printer 21.
After sending the control command to the CPU of No. 3, the number of lines n at which the paper is to be fed must be sent again at 103. After receiving the commands 102 and 103,
In, the printer executes paper feeding for n lines. But,
According to the present invention, by transmitting the command 105, the printer immediately executes the paper feed at 106 to the optimum position for cutting the print paper.

[0012]

According to the present invention, it is possible to provide a user-friendly printer by sending an optimum amount of print paper by sending a control command including a paper feed amount for cutting print paper to the printer. Becomes Further, with regard to application software development, even if the printer model is changed, it can be dealt with without any problems, which is very useful industrially.
