Abstract

PURPOSE:To facilitate the investigation of obstruction by determining a printing mode according to a printing mode setting unit by depressing a set switch and developing printing data and printing control information in a memory by depressing a start switch. CONSTITUTION:When the printer stalls due to some obstruction, a user depresses a reset 6 according to a mode of memory dump of a printing mode setting unit 5 to turn a printing mode of the printer to a memory dump mode, following which a printing control unit 2 having received a reset signal from the reset switch 6 confirms a printing mode indicated by a printing mode setting unit 5 and recognizes the mode of the memory dump, while the control unit 2 is reset. Thereafter, if a start switch 1 is depressed, the control unit 2 develops printing data and printing control information stored in the printer in a memory 3, which are printed at a printing unit 4 as memory dump.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram of a first embodiment of the present invention. Figure 1
The embodiment includes a print control section 2 having a microprocessor control circuit that controls the operation of the printer device, a print mode setting section 5 that sets operational functions when the printer device prints, and a print mode setting section 5 that sets print data and print control information. Memory to store 3
, a start switch 1 that starts printing according to the print mode, a reset switch 6 that forcibly resets the print control section 2, and a printing section 4 that actually performs printing.

Next, the operation of this embodiment will be described. When the printer stalls due to some kind of failure, the user sets the print mode setting unit 5 to the memory dump mode and presses the reset switch 6, thereby determining the print mode of the printer to the memory dump mode. Next, the print control unit 2 that has received the reset signal from the reset switch 6 is reset, checks the print mode specified by the print mode setting unit 5, and recognizes it as the memory dump mode. Thereafter, when the start switch 1 is pressed, the print control unit 2 develops the print data and print control information stored inside the printer device in the memory 3, and prints it from the print unit 4 as a memory dump.

Next, a second embodiment of the present invention will be explained with reference to the configuration diagram of FIG. In FIG. 2, the same reference numerals as in FIG. 1 have the same configuration and function. That is, in the second embodiment, a print control section 2 consisting of a microprocessor control circuit that controls the operation of the printer device, a memory 3 that stores print data and print control information, and a controller that starts printing according to a print mode. The print control unit 2 is activated by turning on the start switch 1 and the power switch of the printer device.
a power-on reset generator 7 that resets the print controller 2; a reset switch 6 that forcibly resets the print controller 2; and a reset signal 10 from the power-on reset generator 6.
12 and reset signals 9, 1 from the reset switch 6
1, and outputs a reset signal and a memory dump request signal to the printing control section 2, an OR gate 8 and a flip-flop 5, and a printing section 4 that actually performs printing.

Next, the operation of the second embodiment will be described. It is assumed that the set input of the flip-flop 5 is S, the reset input is R, the reset input of the print control section 2 is RA, and the memory dump request input is M. First, when the power switch of the printer device is turned on, the reset signal 10 from the power-on reset generation section 7 is inputted to the RA of the print control section 2 through the OR gate 8, and the print control section 2 is reset. 12 is input to R of the flip-flop 5, so M of the print control unit 2 does not operate. When the printer device stalls due to some kind of failure, when the reset switch 6 is pressed, the reset signal 9 passes through the OR gate 8 and is input to the RA of the print control section 2.
is reset, and the reset signal 11 is input to S of the flip-flop 5.
is activated and recognizes that the memory dump request signal has been input. Then, when the start switch 1 is pressed, the print control unit 2 develops the print data and print control information stored inside the printer device into the memory 3, and prints it from the print unit as a memory dump.

0010

As explained above, in the first embodiment of the present invention, when the reset switch is pressed, the print mode is determined according to the print mode setting section, and the print control section recognizes the print mode and performs memory dumping. In this mode, the print data and print information are developed into memory and printed from the print section as a memory dump. Therefore, even if the printer device stalls, a memory dump can be printed, which facilitates troubleshooting and improves maintainability. In addition, in the second embodiment, the reset operation of the print control section is performed by a flip-flop in two ways: control of the power-on reset generation section and control of the forced reset switch. There are effects you don't need.
