Abstract

PURPOSE:To recognize error contents by a host computer by answering the inquiry of the error contents from the host computer by changing a signal line when error or the like is generated while using the printer device. CONSTITUTION:Data transmitted from an outside connector 2 are received by a data reception part 3 and dispatched to a control part 4. In a normal mode, the control part 4 investigates whether the received data are remote control codes or not. When they are the remote control codes, an inside state is set to a remote mode. In the state of the remote mode, control is moved to a remote processing part 11. The remote processing part 11 compares the received character string data with contents displayed on an LCD by the printer device and reflects the result upon the signal line (such as a paper supply request signal, for example) by utilizing a signal control part 12.

2. Description of the Related Art Conventionally, a printer device is an output device used for outputting a processing result on a sheet of paper in a computer system, and it seems that the function of printing out will not change in the future. However, with the development of computer systems, there is an increasing demand for using a printer device on a LAN or the like and for remote operation from an external connection device.

SUMMARY OF THE INVENTION A printer device of the present invention sends a status of a printer device having at least a display section and a parallel unidirectional interface from an external connection device in a mode for displaying the status on the display section. The mode is switched to the remote mode by the control code of the interface, and then the character string sent from the external connection device through the interface is compared with the character string indicating the control of the printer device displayed on the display unit. When they match, it is configured to have a function of notifying the external connection device by changing the level of a predetermined signal line among the signal lines of the interface for a certain period of time.

In the printer apparatus including the present invention, the data receiving section 3 receives the data sent from the external connection apparatus 2. The received data received is passed to the control unit 4. In the control unit 4, when the printer device is in the normal mode, the received data is analyzed byte by byte to check whether it is a remote control code. When the code is the remote control code, the internal state of the printer is set to the remote mode. If not, the process moves to the printing unit 5. When the printer device is in the remote mode, the control is transferred to the remote processing unit 11. The remote processing unit 11 compares the character string received by the data receiving unit 3 with the data that the printer device is about to display on the LCD, and checks whether they are equal. In the signal control unit 12, according to the content determined by the remote processing unit 11, the signal line P

First, from the external connection device 2 to the receiving unit 3
The received data is read (step 100). Next, it is checked whether the printer device of the present invention is currently in the remote processing mode (step 101). If not in the remote mode, it is checked whether the received data is a remote control code (step 106). When the code is the remote control code, the internal state of the printer of the present invention is set to the remote processing mode (step 107). If it is not the remote control code, normal printing processing is performed (step 10).
8). If the remote mode is set in step 101, all the character string data sent from the external connection device 2 is read (step 102). Next, the character string data that has just been read is compared with the character string of the display data that the printer of the present invention normally displays on the LCD (step 103). When the results are the same, the predetermined signal line is inverted (step 104). If they are not equal, do nothing. After that, the external connection device 2 waits for 10 msec so that the change of the predetermined signal line can be confirmed, and then the predetermined signal line is returned to the original state (step 105).
