Abstract

PURPOSE:To make the command system for printer original and to realize arbitrary conversion for character string using the printer by providing commands for conversion data registration on the printer. CONSTITUTION:The printer printing data inputted from a host device 2 is provided with a CPU part 11 controlling the data received from a reception part 3, the printing data to be outputted to a printing part 4, and the data with a storage part 12, a storage part 12 performing at least the reading and writing to a conversion data table by the data from the CPU part 11, and a conversion data table 13 storing conversion data and data to be converted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a received data conversion system for a printing device, and more particularly, it converts data received from a host device into arbitrary data registered in advance by the host device. The present invention relates to a received data conversion method of a printing device such as converting a command into a line feed command.

[0002]

2. Description of the Related Art Conventionally, a printer performs processing corresponding to data received from a host device, and when changing the print result of arbitrary print data, the printer data is changed on the host device side. Was output to.

[0003]

In the above-mentioned conventional printing apparatus, when the printing result is changed, it is necessary to change the print data of the host apparatus and output it to the printing apparatus.
For this reason, there is a drawback that the print data cannot be changed on the printer side. An object of the present invention is to make it possible to obtain an output result unique to a printing device by providing a conversion data registration command on the printing device side.

[0004]

According to the received data conversion method of a printing device of the present invention, in a printing device for performing a printing operation of data input from a host device, the data received by a receiving part is controlled and output to the printing part. Print data control,
A CPU unit for controlling data with a storage unit, and the CP
A storage unit that writes and reads at least the conversion data table according to the data passed from the U unit;
And a conversion data table for storing the converted data.

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. The configuration of the block diagram of FIG. 1 will be described.
The printing apparatus 1 including the present invention includes a receiving unit 3 that receives data sent from the higher-level device 2 and a storage unit that determines whether the data received by the receiving unit 3 is a registration command, converted data, or other data. 12 or CP passed to the printing unit 4
A storage unit 12 for registering or comparing the conversion data table 13 with respect to a registration command or data passed from the U unit 11, a conversion data table 13 for converting the converted data into conversion data by the storage unit 12, and a CPU. Part 1
Printing unit 4 that performs printing operation based on the data passed from 1.
Composed of.

Next, the printing operation of the printing apparatus 1 including the present invention will be described with reference to the flowchart of FIG.

First, the receiving unit 3 receives the data sent from the higher-level device 2 (step 21). The CPU section 11 is
It is determined whether the data received by the receiving unit 3 is a registration command (step 22). If it is a registration command,
The CPU unit 11 passes the converted data and the converted data passed from the higher-level device 2 together with the registration command to the storage unit 12. The storage unit 12 writes the converted data and the converted data in the converted data table 13 (step 23).

If it is not a registration command, the CPU section 11
Notifies the storage unit 12 of the data. The storage unit 12 determines whether the data does not match the converted data or the converted data table 1
3 is searched (step 24). If the data does not match the converted data, the storage unit 12 sends the data received from the CPU unit 11 to the CPU unit 11 as it is. When the data and the converted data match, the storage unit 12 reads the converted data corresponding to the matched converted data from the conversion data table 13 and sends it to the CPU unit 11 (step 25). The data sent from the storage unit 12 is transferred to the CPU unit 1
1 is passed to the printing unit 4, and the printing unit 4 performs a printing process based on the passed data (step 26).

[0010]

As described above, according to the present invention, by providing a conversion data registration command in the printing device, it is possible to create a command system original to the printing device, for example, converting it into a page break command. There is. Further, by not limiting the lengths of the converted data and the converted data, it is possible to realize the conversion of an arbitrary character string by the printing device.
