Abstract

PURPOSE:To discriminate the cause of a defective imprint result if detected by switching the action mode to imprint not only the character data contained in the received data but the dump data showing the function characters and the error information. CONSTITUTION:A control part 3 stores the error information the damp data in case the wrong use of the function characters or the function character that is not replaced by a printer device is detected. Then the part 3 gives an imprint indication to a imprint part 4 when the end of a page, i.e., the function character indicating the start of imprint is detected. Thus the part 3 reads the character data out of a memory 1 and supplies it to the part 4. The part 4 converts the damp data and the error information stored in the memory 2 into the memory 1 after the information is converted into a treatable form by the part 4. Then a print indication is given to the part 4 and the damp data and the error information are supplied to the part 4 from the memory 1. Thus the part 4 imprints the damp data and the error information after the character data is imprinted.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a printer device.

[Conventional technology]

Conventionally, a printer device is an output device used in a computer system to output processing results on paper, and its printing function will not change in the future. However, as the data processed by computer systems expands into various formats such as character images and line drawings, the data output by printers also becomes more diverse, and the data used to control printers also become more complex.

In such a complex system, when a printer device that requires complex control is used, there is a high probability that problems will occur with other devices in the system, the communication network, or the software used.

[Problem that the invention seeks to solve]

The conventional printer device described above simply prints according to the received data, and even if the print result differs from the expected value, it is possible to determine whether there is an error in the received data or because the received data is correct but the printer is malfunctioning. There is a problem in that it is necessary to use specialized equipment to determine whether or not there has been fraudulent printing.

An object of the present invention is to provide a printer device that can confirm received data and point out errors such as usage violations without requiring the use of any special equipment.

[Failure to solve the problem]

The printer device of the present invention has a first printer that stores first data obtained by converting received data from a host device into a format necessary for printing.
a second memory for storing 4-bit data obtained by dividing the character data into 4-pit units in the order of reception, converted into a hexadecimal number, and converted into a JIS code corresponding to the hexadecimal number, and error information in the received data. a memory, a printing section that prints on paper according to the data stored in the first memory, an operation mode switching section that switches the operation mode between a first mode and a second mode, and the first mode. When in the second mode, create the first data, instruct to store the first data, and instruct to print the first data every time one page ends, and create the first data when in the second mode. and instructing to store the first data, creating the second data, detecting the error information, and instructing to store the second data and error information, and storing the first data every time one page ends. following the printing instruction and the printing of the first data, the format conversion for printing the second data and error information, and the first of the format-converted data.
and a control section that instructs the storage of the information in the memory and instructs the printing section to print.

〔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.

As shown in FIG. 1, this embodiment includes a first memory 1, a second memory 2, a control unit 3 mainly composed of a microprocessor, and a printer for printing received data to be printed on paper. 4 and an operation mode switching section 5 that switches the operation mode.

In FIG. 1, data received from the host device is sent to the control unit 3.
Receive at. Also, the state of the operation mode switching section 5 is determined by the control section 3.
0 microprocessor, the first mode is when the microprocessor's contents are II □ II, and the second mode is when it is 111n.

First, the operation in the first mode will be explained.

The control section 3 extracts the received data in 1-byte units in the order in which it is received, performs format conversion to convert it into a format that can be handled by the printing section 4, and stores it in the memory 1 repeatedly. When the end is detected, a printing instruction is given to the printing unit 4 to print the received data.

Next, the operation in the second mode will be explained.

The control section 3 extracts the received data in byte units in the order of reception, converts it into a format that can be handled by the printing section 4, and stores it in the memory 1. ¥, but before this operation, the 1 extracted
When the 4-bit data obtained by dividing the byte data into 4-bit units is converted into 2-digit hexadecimal numbers, the operation of storing the dump data, which is converted into 2-byte JIS code, into the memory 2 is repeated.

Here, the received data includes, in addition to character data representing printed characters, functional characters for controlling the format or functional characters for controlling the printing operation.

Functional characters may be used in a limited manner, and if they are used in a manner other than the restricted method, the functional characters will be ignored and the printed result will be different from the printed result intended by the data creator.

Therefore, when the control unit 3 detects a failure to use a functional character or a functional character that cannot be handled by the device, the control unit 3 stores error information corresponding to the type of abnormality in the memory 2 following the dump data.

Next, when the control section 3 detects the end of one page, that is, a functional character instructing the start of printing, it instructs the printing section 4 to print, and first outputs the character data stored in the memory 1 one after another. Supply to 4. Next, the dump data and error information stored in the memory 2 are converted into a format that can be handled by the printing unit 4 and stored in the memory 1. After that, the printing unit 4 is instructed to print, and the dump data and error information stored in the memory 1 are Data and vA information are supplied to the printing unit 4.

After printing character data, the printing unit 4 prints dump data and error information.

With the above operations, the processing of one page is completed, and the subsequent data received from the higher-level device is processed.

〔Effect of the invention〕

As explained above, the printer device of the present invention switches the operation mode and when there is a problem with the character data in the received data, the printer device can process the received data without using any special equipment to determine the cause of the problem. Since errors such as confirmation and incorrect use of functional characters can be pointed out, the efficiency of system use can be improved.
