Abstract

PURPOSE:To operate a printer without operating a higher-order device by executing the code set by the switch operation in the same manner as the code from the higher-order device. CONSTITUTION:The code passing an interface part 12 is supplied to a data processing part 15 to control a printing part 11. Meanwhile, an operation part 14 is provided with a code setting switch, and the code due to this switch is supplied to the processing part 15 to operate the printer without operating the higher-order device, and thus, the operation of the higher-device is not prevented from being interrupted by the printer operation.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to printers.

[Conventional technology]

Conventional printers operate in accordance with the sent code when a code instructing the type of character, character size, number of character bits, line feed behavior, etc. is sent from a host device.

[Problem to be solved by the invention]

The above-mentioned conventional printers do not operate unless a code is sent from the higher-level device, so the operator has the disadvantage of having to operate the higher-level device each time the printer is operated. Another drawback is that when the printer is running, the operation of the host device must be interrupted in order to operate the printer.

[Means to solve the problem]

The printer of the present invention is a printer that prints according to a code sent for printing instructions from a host device, and includes: a switch that can set the code; a display section that displays the code set by the switch; and a switch. When the code is set and the set code is instructed to be executed, the controller has a data processing unit that processes the code set by the switch in the same way as the code sent from the host device. There is. [[Function]] It is equipped with a switch for setting a code, and the code set by operating the switch is executed in the same way as the code sent from the host device, so the operator can operate the printer without operating the host device. You can make the same work.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the printer of the present invention, FIG. 2 is a partial plan view showing the arrangement of main parts of the operation panel section 14 shown in FIG. 1, and FIG. 3 is a data processing diagram shown in FIG. 1. 3 is a flowchart showing the processing of the unit 15. FIG.

The printer of this embodiment includes a printing section 11, an interface section 12, a data storage section 13, an operation panel section 14, and a data processing section 15.

The printing unit 11 performs operations such as printing and line feed in accordance with instructions from the data processing unit 14. The interface section 12 has an upper mounting @(
It receives various 8-bit codes sent from (not shown). Among the codes processed by the data processing unit 15, the data storage unit 13 stores codes that are held and used, such as codes for setting the number of character pitches, character size, etc. The operation panel section 14 has switches 21, 22, 23, 24, 25 and a display section 26. switch 21
．． 22, 23, 24, and 25 are all switches that turn on when pressed. The display section 26 is composed of two sets of 7-segment light emitting diodes to display 8 bits in 2-digit hexadecimal numbers. Data processing section 1
5 is a mode similar to the conventional mode (hereinafter referred to as cylinder 1 mode) in which the interface unit 12 accepts a code received from a host device, and switches 21, 22, . ~2
It has a mode (hereinafter referred to as cylinder 2 mode) that accepts an 8-bit code set by the operation of step 5.

Next, the second mode of processing by the data processing section 15 will be explained. Here, for convenience of explanation, the 8-bit code is divided into the upper 4 bits and the lower 4 bits, and each is expressed as a 1-digit hexadecimal number.

Since the data processing unit 15 is normally in the first mode, it first determines whether or not it will be in the second mode (step 31). That is, when the operator presses the switch 22 once while pressing the switch 21, the data processing section 15 enters the second mode.

In the second mode, the data processing section 15 initializes the 8-bit code to 00'' (step 32), and displays the display section 2.
Display “00” in 6. Next, the data processing unit 15 determines whether to return to the first mode (step 33).
. That is, when the operator presses the switch 22 twice while pressing the switch 21, the data processing section 15 returns to the first mode.

When not returning to the first mode, the data processing unit 15 accepts code settings by operating the switches 23 and 24 (
Step 34). That is, each time the switch 23 is pressed, the value of the upper 4 bits of the code changes from O→1→2→...→F.
It changes as →0→... Furthermore, each time the switch 24 is pressed, the value of the lower 4 bits of the code changes in the same way as the upper 4 bits.

Next, the data processing unit 15 determines whether to execute the code set in this way (step 35). That is, when the switch 25 is pressed, the data processing section 15
executes the set code (step 36).

When executing a code such as a character or line feed, the data processing section 15 converts the code into data in a format that the printing section 11 operates on, and outputs the converted data to the printing section 11.

Furthermore, when executing a code for setting the number of character pitches and character size, the data processing unit 15 stores the code in the data storage unit 13, and uses the stored code when processing codes such as characters. Process in combination. The code stored in the data storage unit 13 is held until a new code is stored in its place. After executing the code, the data processing unit 15 returns to step 33 and repeats the above-described process until it determines to return to the first mode.

Below is an example of how to run the code.

For example, when three codes r41, OD, and OA are executed, the characters rAJ are printed and a new line operation is performed. Also, for example, four codes r1B, 65.32.3
2" is a code for enlarging a character twice both vertically and horizontally. When this code is executed, the next time the data processing unit 15 receives a character code, the received code will be enlarged twice vertically and horizontally. and printed.

[Effects of the Invention] As explained above, the present invention includes a switch for setting a code, and executes the code set by operating the switch in the same way as a code sent from a host device. This has the effect that the operator can operate the printer without operating the host device, and as a result, there is no need to interrupt the operation of the host device in order to operate the printer.
