Abstract

PURPOSE:To easily alter the number of printing figures of one line, by providing a switch for setting the number of printing figures, and judging and setting the number of printing figures by reading the state of said switch. CONSTITUTION:The content of a switch reading port 61 is read to judge whether the number of set figures are 90 or 136 figures and the judged result is stored in RAM2. When data 100 is received from a host computer through a communication interface 7, a microprocessor 1 judges whether a received data amount has reached the set number of printing figures according to the control program stored in ROM3. When said data amount has not reached, received data is developed on printing data as it is by using a character generator and printing data is stored in buffer 5 to finish processing. When the received data amount has reached the set number of figures, an order is applied to a motor driving part 8 to perform return and line feed operation and the received data is developed as the printing data of the next line and the printing data is stored in the buffer 5 to finish processing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] The present invention relates to a printing device suitable for printing by varying the printing width of one line.

[Technical background of the invention and its problems] In conventional printer devices, the print width of one line is fixed. It was necessary to set the farthest printing position in the control section of the printer device using a command from the computer. Therefore, when executing software for an 80-column printer using a printer with a printing width of 136 digits per line, it is necessary to modify the program of the host combicoater, and the printing width of one line can be easily changed. The drawback was that it could not be done.

[Object of the Invention 1] In view of the above-mentioned drawbacks, it is an object of the present invention to provide a printer device in which the number of printing digits per line can be easily changed.

[Summary of the Invention] The present invention provides a printer device that includes a switch means for setting the number of printing digits in one line, a switch means that reads the setting state of the switch, stores the set number of printing digits, and operates the device according to the number of printing digits. The above object is achieved by providing a means for setting the number of printed digits so as to increase the operation speed.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the printer device of the present invention. A system bus 50 from the microprocessor 1 that executes the printer control program includes a RAM 2 that is used as a work area when the control program is executed.

A ROM 3 for storing the control program, a character generator 4 for generating a print pattern when the received data is converted into print pattern data b=178, and a buffer 5 for temporarily holding the print pattern. Input ports 1 to 6 that read data indicating the external state of the printer device, a communication interface 7 that receives data from the boss mill computer, and a motor that drives the motor based on operation control signals output from the microprocessor 1. A head drive unit 9 that drives the head based on operation control signals output from the drive unit 8 and the microprocessor 1 is connected. In addition, a switch reading boat 61 is installed in the input boat 4.
-61 is connected to a switch 1o for setting the number of printing digits (for example, either 136 digits per line or 80 digits per line), and this switch 10 is connected to the operation panel of the printer, etc.
It can be installed in a location that is easy for the operator to operate. Further, a printing pad 11 is connected to the spatula 1 to the drive section 9c.

Furthermore, the motor drive unit 8 drives a motor that operates the carriage and paper feeding mechanism.

Next, the operation of this embodiment will be explained. First, the state of the switch 10 is read into the switch read board 61 stored in the input ports 1 to 6.Next, the microprocessor 1 follows the control program stored in the ROM 3 and executes the process shown in FIG. The process shown in the flowchart is executed. That is, in step 201, the contents of the switch read boat 61 are read, and in step 20
In step 203, it is determined whether the set number of digits is 80 digits or 136 digits, and if it is 136 digits, the number of printing digits is set to 1.36 digits in step 203, and this is stored in the RAM 2. If the number of H digits is 80 (at step 202), the number of digits to be printed is set to 80 digits at step 20/l, and this is stored in the RAM 2.

Thereafter, when data 100 is received from the host Combicoater via the communication interface 5, the microprocessor 1 executes the control program stored in the ROM 3.
Processing as shown in the flowchart of FIG. 3 is executed.

That is, in step 301, it is determined whether the amount of received data has reached the number of printing digits set in flowcharts 1 through 1 shown in FIG. If not, in step 302, the received data is expanded as it is into print data using the character generator 4, the expanded print data is stored in the buffer 5, and the process ends. In step 301, if the amount of received data has reached the set number of print digits, the process goes to step 303, where a command is given to the motor drive unit 8 to perform return and change operations. Thereafter, in step 304, the received data is developed as print data for the next line, and this developed print data is stored in the buffer 5, and the process is terminated. The subsequent processing is done using buffer 5.
The developed print data is read and compared and sent to the printing rad 11 via the head drive unit 9, and printing is performed using the designated number of digits.Since this part of the operation is already known, the 5T system is not suitable. Illustrations and explanations are omitted.5 tables are omitted.

If J: is used in this embodiment, the number of printing digits in one line can be easily changed by switching the switch 10. Therefore, it is possible to use software assuming printers with different print widths with one printer device. Also, the first
Since the hardware configuration of the printer device shown in the figure is hardly changed compared to the conventional one, the above effects can be achieved without increasing the cost of the device.

In the switch 10 of the above embodiment, an example has been described in which two types of digit numbers are selected and switched, namely, 136 digits per line or 80 digits, but it is possible to combine a plurality of these switches. , it is possible to switch between two or more types of printing digit numbers using a similar configuration.

[Effects of the Invention] As described above, according to the printer device of the present invention, the switch for setting the number of printing digits is inserted, and the state of this switch is read to determine and set the number of printing digits. This has the effect of easily changing the number of digits printed in one line.
