JPS62193836A - Initialization device of printer - Google Patents

Abstract

PURPOSE:To enable initialization of an enlarged character through the main body of a printer by providing an initialization circuit consisting of a switch for initialization of one of many character enlargement functions and a control circuit which outputs an initialization signal in accordance with the status of the switch. CONSTITUTION:When switches 11-13 are OFF, an ordinary character 21 is initialized by a control circuit. When the switch 11 alone is turned ON, a character which is doubled vertically is initialized by the control circuit 3. When the switch 12 is turned ON, a doubled character 23 is initialized. Further both switches 11, 12 being turned ON, a character which is doubled vertically and horizontally is initialized, and in this case, the combination of switches 11, 13 initializes vertically double and horizontally triple character enlargement. When the switches 12, 13 are turned ON simultaneously, the switch 12 is preferred by a control circuit 2. It is only when an electric power is turned ON and also a printer is reset at the time of initialization that initialization is performed by the switch 12.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an initial setting device for a printer that can initialize enlarged characters. .

[Conventional technology]

Many small printers currently in use have many functions, and many also have character enlargement functions. In such printers, character enlargement operations are generally performed by commands from a host device such as a personal computer, and the initial setting is always normal characters. Therefore, it is not possible to independently set or change enlarged characters on the printer side.

However, when operating a system including such a printer, there may be cases where it is desired to print characters fixed to certain enlarged characters. In such cases, with conventional printers, commands must always be sent from the host device as described above.

[Problem that the invention seeks to solve]

The printers that have the conventional character enlargement function mentioned above are
The printer body was not equipped with an initial setting operation means for enlarged characters, and the character enlargement function was driven by commands from a host device such as a personal computer.

For this reason, the commands became complicated and could not be easily changed.

SUMMARY OF THE INVENTION An object of the present invention is to provide an initial setting device for a printer that allows initial setting of enlarged characters easily using only the printer itself without using a host device.

[Failure to solve the problem]

The configuration of the printer initialization device of the present invention includes a switch for initializing one of a plurality of character enlargement functions;
The present invention is characterized in that it has an initial setting circuit including a control circuit that outputs an initial setting signal depending on the state of the switch, and enables the initial setting when the printer is powered on and reset.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an initial setting circuit for initializing enlarged characters according to an embodiment of the present invention, FIG. 2 is a diagram showing the types of characters, and FIG. It is a flat country.

The DIP switch 1 shown in FIG. 3 consists of switches 11 to 18 for individually setting ON-OFF, and is arranged on the back side of the printer body along with other DIP switches and the like. now,
When the switch 11 is turned on, double-height enlarged characters are initially set. Similarly, when the switch 12 is ON, 2x horizontal enlargement is initially set, and when switch 13 is ON, 3x horizontal enlargement is initially set. All three switches 11 to 13 are now OFF.
In this case, the control circuit 3 in FIG. 1 initializes a normal character such as 21 in FIG. 2.

Furthermore, when only the switch 11 is turned on, the control circuit 3 initializes double-height enlarged characters such as 22 in FIG. 2, and when the switch 12 is turned on, the same Double horizontally enlarged characters such as 23 are initially set.

Furthermore, both 11 and 12 turn ON [If they turn on, 2 in Figure 2
Characters enlarged vertically and horizontally twice, such as 4, are initially set, and the relationship between the n1 switches 11 and 13 is also set similarly.

If switches 12 and 13 are turned on at the same time,
The control circuit 2 gives priority to the double enlargement of the switch 12.

Initial settings using this switch 12 are performed only when the printer is reset at power-on and initial settings.

〔Effect of the invention〕

As explained in detail above, according to the present invention, enlarged characters can be initialized by the printer itself, so there is no need to change programs or input commands to enlarge characters. There is.
