JPH0872332A - Damp output method in printer - Google Patents

Abstract

PURPOSE: To easily conduct damp output even when a control signal other than receiving data is received by performing the interruption processing of a printer in the case of a usual printing mode and performing the printing output of a specific character in the case of a damp output mode. CONSTITUTION: An editing processing part 26 receives an I-PRIME-N signal to judge a damp output mode or a usual printing mode. In the case of the damp output mode, the editing processing part 26 reads a specific character from a CGROM 13 to perform printing output in order to show that the I- PRIME-N signal is inputted. The specific character is selected from characters not used as figure characters. In this case, the resetting processing of a printer is not performed. In the case of the usual printing mode, a CPU 11 performs the resetting processing of the printer.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dump output method in a printer device.

[0002]

2. Description of the Related Art Conventionally, in a printer device, when there is a problem in print output, by operating an operation panel, a data signal received via an interface is converted into numeric characters and printed as a dump list. be able to. Then, the operator can analyze the dump list.

Therefore, when the printer device receives the data signal, the printer device reads the bit map data of the numerical characters corresponding to the data signal from the CGROM and dumps the data according to the bit map data.

[0004]

However, in the dump output method in the conventional printer device described above,
When a control signal other than the received data, for example, an I-PRIME-N signal in the Centro interface is received,
The I-PRIME-N signal itself cannot be printed out in the dump list, and the I-PRIM-N signal cannot be printed out.
The E-N signal is processed as a reset signal.

Therefore, when the I-PRIME-N signal is received from the host device in the dump output mode, the printer device is reset and the dump output mode returns to the normal print mode. As a result, in a system in which the I-PRIME-N signal is frequently output from the host device, the dump output is stopped every time the I-PRIME-N signal is output, and the printer device outputs the dump. It will be difficult.

Further, for example, in a printer device capable of performing external character registration, a printer device capable of switching the printing speed, etc., an IP
The RIME-N signal is now treated as a soft reset signal rather than as a complete reset signal. In this case, the printer device is not completely reset by the I-PRIME-N signal,
A part of the state set by the received data until the PRIME-N signal is received remains.

Therefore, if the dump output cannot be performed continuously and the reception timing of the I-PRIME-N signal is unknown, the received data cannot be analyzed. The present invention solves the problems of the dump output method in the conventional printer device,
An object of the present invention is to provide a dump output method in a printer device that can easily output a dump even when a control signal other than the received data is received and can analyze the received data.

[0008]

Therefore, in the dump output method in the printer device of the present invention, the data signal received from the host device is converted into the corresponding numeric character, and the numeric character is printed out. Further, when the control signal is received from the host device, it is determined whether the normal print mode or the dump output mode is set.

If the normal print mode is selected,
When the printer device performs an interrupt process and is in the dump output mode, the control signal is converted into a specific character selected in advance, and the specific character is printed out.

[0010]

According to the present invention, as described above, in the dump output method in the printer device, the data signal received from the host device is converted into the corresponding numeric character and the numeric character is printed out. Further, when the control signal is received from the host device, it is determined whether the normal print mode or the dump output mode is set.

If the normal print mode is set,
When the printer device performs the interrupt process and is in the dump output mode, the control signal is converted into a preselected specific character, the specific character is printed out, and the interrupt process of the printer device is not performed. In this case, the specific character is output to the dump output list at a position corresponding to the timing when the control signal is input to the printer device.

Embodiments of the present invention will now be described in detail with reference to the drawings. 1 is a block diagram of a printer device according to an embodiment of the present invention, and FIG. 2 is a functional block diagram of the embodiment of the present invention. In FIG. 1, 11 is a CP

Reference numeral 14 is an operation panel, 15 is an input / output I / O port for detecting a pressed state of an operation key of the operation panel 14, and 16 is an input / output I / O port of the Centro interface. , 8-bit data signal DATA is received from the host device. Further, 17 is a print head, 18 is a head driver for driving the print head 17, and 19 is a head controller for controlling the drive of the print head 17.

Next, the CPU 11 will be described.

In FIG. 2, 11 is a CPU and 13 is a CG.

Is a head controller. Further, 25 is a reception buffer that temporarily stores the data signal DATA and I-PRIME-N signal, 26 is an edit processing unit that analyzes and edits the data stored in the reception buffer 25, and 27 is an operation panel 14. It is a specific switch pressing detection means for detecting the pressing state of the specific switch.

Next, the operation of the printer having the above construction will be described. FIG. 3 is a flowchart showing the operation of the printer device showing the embodiment of the present invention. First, in the case of dump output, the operator depresses a specific switch (not shown) on the operation panel 14 (FIG. 2) and turns on the power of the printer device in that state. Next, the specific switch depression detecting means 27 of the CPU 11 reads the I / O port 15 of the operation panel 14 according to the program in the program ROM 12 (FIG. 1), and when it detects that the specific switch is depressed, the editing process is performed. The section 26 shifts from the normal print mode to the dump print mode.

When the edit processing section 26 shifts to the dump print mode, the CPU 11 causes the data signal D via the I / O port 16 for input / output of the Centro interface.
The ATA is received and stored in the reception buffer 25. Then, the edit processing unit 26 reads out the data signal DATA from the reception buffer 25 and converts the data signal DATA into the bitmap data of the corresponding numeral character by using C
The address of the GROM 13 is calculated, and the bit map data of numeric characters is read from the CGROM 13.

Then, the edit processing unit 26 sets the bitmap data in the head controller 17.
When the bit map data is set in the head controller 17, the head driver 18 drives the print head 17 according to the bit map data and outputs a dump. By the way, when the printer device receives an I-PRIME-N signal from a host device (not shown), the CPU 1 normally operates.
1 is interrupted, but the I-PRIME-N
When the signal is a dump output, it is not preferable that the CPU 11 is reset.

Therefore, the edit processing unit 26 causes the IP
When the RIME-N signal is received, it is determined whether the dump output mode or the normal print mode is set. Then, in the dump output mode, the edit processing unit 26 reads the specific character from the CGROM 13, and the I-PRI
It is printed out to show that the ME-N signal has been input. The specific character is selected in advance from characters that are not used as numeric characters. In this case, the reset process of the printer device is not performed.

On the other hand, in the normal print mode, the CPU 11 resets the printer. Step S1 The specific switch is depressed, and the printer is powered on in the depressed state. Step S2 The CPU 11 reads the I / O port 15 of the operation panel 14. In step S3, it is determined whether the pressing of the specific switch is detected. When the pressing of the specific switch is detected, the process proceeds to step S9, and when the pressing of the specific switch is not detected, the process proceeds to step S4. Step S4 shifts to the normal print mode. In step S5, it is determined whether the I-PRIME-N signal is input. When the I-PRIME-N signal is input, the process proceeds to step S8, and when the I-PRIME-N signal is not input, the process proceeds to step S6. In step S6, printing is performed according to the data signal DATA. In step S7, it is determined whether the data signal DATA is the print end code. If it is the print end code, the process is terminated, and if it is not the print end code, step S
Return to 5. Step S8 The printer device is reset. In step S9, the dump output mode is entered. In step S10, it is determined whether the I-PRIME-N signal is input. If the I-PRIME-N signal is input, the process proceeds to step S12, and if the I-PRIME-N signal is not input, the process proceeds to step S11. In step S11, printing is performed according to the data signal DATA. In step S12, the specific character is printed. In step S13, it is determined whether the data signal DATA is the print end code. If it is the print end code, the process is ended, and if it is not the print end code, the process returns to step S10.

FIG. 4 is a diagram showing an example of the dump output list in the embodiment of the present invention. In this case, "0" to "9" and "A" to "F" are used as the numerical characters, and two-digit (digit) numerical characters are dumped and output. Therefore,
"XX" is used as a specific character indicating that the I-PRIME-N signal has been input. Further, the specific character "XX" is output to the dump output list at a position corresponding to the timing when the control signal is input to the printer device.

Therefore, the timing at which the I-PRIME-N signal is input is reflected in the dump output result, and the dump output can be sufficiently analyzed. It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be made based on the spirit of the present invention, and they are not excluded from the scope of the present invention.

[0023]

As described above in detail, in the dump output method in the printer device, the data signal received from the host device is converted into the corresponding numeric character and the numeric character is printed out. Further, when the control signal is received from the host device, it is determined whether the normal print mode or the dump output mode is set.

Then, in the normal print mode,
When the printer device performs an interrupt process and is in the dump output mode, the control signal is converted into a specific character selected in advance, and the specific character is printed out. Therefore,
The dump output is not stopped even when a control signal other than the received data is received.
