Abstract

PURPOSE:To remove a burden of a data processor, and to accelerate processing by dividing data into a plurality of groups and transmitting them and converting characters and dot patterns in line units and making them to be contained into a buffer memory. CONSTITUTION:Data intended to be outputted to a printer 2 from the data processor 1 are divided to a plurality of groups and transmitted at every character-kind in line units. A control section 3 receives the data and converts characters and dot patterns in line units while referring to a conversion index table 9 and a dot pattern memory 15 at every character-kind of each group, and previously over-laps all groups and makes them contain into the buffer memories 11, 12 prior to printing. A printing head 13 with a nozzle for a plurality of dots in the row direction is swept and printed in the line direction only once and one line is printed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing method for high-speed printing of data such as complex figures, 9 characters, numbers, etc., and for educating users about the life of the machine.

When printing complex figures, two characters, numbers, and other data by combining them, a printing method such as the one described by Jyusuji is used.

In other words, the data processing device converts the data in one print line into multiple pieces of data n(11, D(21...D

When printing is completed after Y processing, data D (21,
D (31...p Since the process has to be repeated several times, the printing speed becomes slow, the life of the mechanical parts is shortened due to the sweeping process, and there are disadvantages in that it places a heavy burden on the data processing device.

The present invention has been made to eliminate the above-mentioned drawbacks, and its purpose is to speed up processing by reducing the burden on data processing equipment that was unavoidable with conventional methods. There is a need to provide a method for reducing the number of times of movement, shortening the time required for movement, and extending the service life.

Embodiments of the present invention will be described in detail below with reference to FIG. FIG. 1IE1 is a diagram showing the configuration according to an embodiment of the present invention. When the data lI & 31 device 1 sends print data to the print data reading circuit 7 built in the printing device 2 and a command signal to the command reading circuit 6, Built-in printing device 2,
For example, the control circuit H1 built into the micro-processor detects this, reads the print data sent from the data processing device 1 to the reading circuit 7, and converts it into a one-character C, D pattern, which will be described later, by the print digit converter circuit 8. Then, the data processing device 1 completes sending out all the print data, and the control section status display circuit 5 indicates that the superimposition is completed. ?If detected, it will be a print command signal.Command reading circuit 6
The control circuit 10 receives this and reads the contents of the printing section status display circuit 16.

After sending a reading command signal to the reading circuit 6, the above-mentioned food group (llt'1 character data character data code) is sequentially sent to the data reading circuit 7 (hereinafter referred to as code group C2).

According to the present invention, the data processing device sends the data to be outputted to the printing device by dividing it into a plurality of #s for each character S type in units of Y lines, and the wJ control section sends this data in units of Y lines. Then, character/do/do pattern conversion is performed line by line by referring to the character type of each group, conversion index table, and dot pattern memory (prior to printing);

All the groups are stored in a superimposed manner in the file memory, and the barbs are swept once in the row direction to complete the printing of one line Y, so that the printing with several nozzles in the column direction is completed. In addition to saving sweep time and improving continuity, this method also has the effect of extending the life of mechanical parts by reducing the number of sweeps for printing and decoding.

Rida, this 9th edition is not only a printing device, but also an output device that does not change the result depending on the order of stacking.
