Abstract

PURPOSE:To eliminate necessity to purchase a printer device due to the difference of an interface, etc., by analyzing an interface parameter signal and determining which kinds of conversion is needed for general data and control data. CONSTITUTION:The data to be outputted from a computer main body are received through a connector changing device 8a to a data input part 1. On the other hand, a parameter input device 7 sends the information such as the model name of the printer device and an interface name to a parameter input part 2 as the interface parameter signal. Then, the information are received. The interface parameter signal to be received in the input part 2 is analyzed by an analyzing part 3. After that, it is determined which kind of the conversion is needed for the general data and control data. Based on the determined information of the analyzed part 3, a general data converting part 4 executes the conversion of the general data to be received from the computer main body and a control data converting part 5 executes the transformation of the control data.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a compatibility method for printer devices, and in particular, to a system that includes compatibility so that printer devices with different interfaces and control data can be connected to any computer main body. The present invention relates to a compatibility method for printer devices.

[Conventional technology]

Conventionally, there are various interfaces for using a printer device, and when the interfaces are different when connecting to a computer main body, a printer device with the same interface is prepared and connected.

Also, depending on the printer device, the control data for changing the size of kanji (points), line pitch, and column pitch may be different or cannot be used at all. Since the printing results are incorrect, the user has to change the program each time they use it.

[Problem to be solved by the invention]

When using the conventional printer device described above, it is necessary to have a printer device that matches the interface and control method of the computer main body, and if the interface is different, it is necessary to purchase a new printer device with the same interface. , there is a problem that costs are incurred.

Furthermore, control data differs depending on the type of printer, and even when connected to the same computer, the computer side creates a print program for each printer.

This program creation has a problem in that it increases the number of man-hours required to create the program, such as investigating and organizing the control data of each printer device.

An object of the present invention is to eliminate the need to purchase printer devices due to differences in interfaces and control methods, eliminate the need to investigate and organize control data for each printer device, and enable common use with the same printing program. An object of the present invention is to provide a compatibility method for printer devices that can reduce manufacturing man-hours.

A data conversion device consisting of:

〔Example〕

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

FIG. 1 is a block diagram of one embodiment of the present invention.

The printer compatibility system shown in FIG. 1 includes a data converter 9 that converts general data and control data in order to match the interface between the computer and printer;
-! It consists of a parameter input device 7 that sends interface parameter information necessary for converting data and control data to a data conversion device 9 as an interface parameter signal.

Furthermore, the data conversion device 9 includes a data input section 1 that receives data output from the computer main body, a parameter input section 2 that receives and stores interface parameter signals input from the parameter input device 7, and an interface of the parameter input section 2. Analysis unit 3 that analyzes parameter signals and determines what kind of general data and control data needs to be converted; general data that performs conversion processing of general data received from the computer main body based on information determined by the analysis unit 3; A conversion unit 4, a control data conversion unit 5 that converts the control data received from the computer based on the information determined by the analysis unit 3, and a data output unit that outputs the converted general data and control data to a printer device. It consists of section 6.

Next, the operation will be explained.

Data output from the computer main body is received by the data input section 1 via the connector conversion device 8a. Connectors having different shapes depending on the interface are fixed by the connector conversion device 8a and connected to the above conversion device.

On the other hand, the parameter input device W7 sends information on the model name of the printer device and the interface name (for example, Centronics interface, ODA interface, etc.) to the parameter input unit 2 as an interface parameter signal, and receives the information.

The interface parameter signal received by the parameter input section 2 is analyzed by the analysis section 3, and it is determined what kind of general data needs to be converted and what kind of control data needs to be converted.

The general data converter 4 converts the general data received from the computer main body based on the information determined by the analyzer 3, and the control data converter 5 converts the general data received from the computer main body based on the information determined by the analyzer 3. Performs conversion processing on the received control data. The converted general data and control data are combined and rearranged and sent to the data output section 6.

When outputting to a printer device, the connection is also made via the connector conversion device 8b as shown in FIG.

FIG. 2 is an explanatory diagram showing the data conversion method of the embodiment shown in FIG.

FIG. 2(a) shows an example in which control data is added before and after general data as the input data 11, and the control content is to enlarge the character twice in the horizontal direction. This data is converted as data 15 using parameter 12 with reference to conversion tables 13 and 14 in FIG. 2(b), and is output to the printer device.

In this way, there is no need to purchase printer devices together due to differences in interfaces and control methods, and there is no need to investigate and organize control data for each printer device, as the same printing program can be used in common.
It is possible to reduce the number of man-hours required for manufacturing grams.
