ABSTRACT:
In a line printer, an integrated meter package developing a clock incorporates a microprocessor receiving a line printed signal, power on voltage, and a preset ribbon exhaust count in order to compute in reference to the clock, and selectively display on an alphanumeric display panel, the total the lines printed, total on hours, total print hours, preset ribbon exhaust count, and number of print lines remaining until exhaustion of the ribbon. The microprocessor stores accumulated values to a non-volatile electrically programmable memory upon receipt of a power going down signal warning of incipient power off. The microprogrammed control is adaptable to maintain general maintenance and fault histories and periods.
