Abstract

PURPOSE: To reduce a burden in a controller, by controlling a printer with interruption processing, by producing an interruption signal from a timer, if a serial printer is in failure.
CONSTITUTION: If the serial printer 2 is in failure, a failure signal is fed to the line 4, a timer 5 is started with a microprocessor μPU1 after a given time, and after a set value is counter and the time-out signal C' is output. The signal C' is given to μPU1 and OR gate 6, and interruption signal is fed to μPU1 from the gate 6. The μPU1 judges the interruption based on the signal C' from the timer 5 and recognizes the failure of the device 2 by that the status signal F from the line 4 is risen.
