SYSTEM FOR PREVENTING LOSS OUTPUT DATA OF POWER INTERRUPTION PRINT

摘要

PURPOSE: A printer output data missing prevention system is provided to increase data storage time by implementing low power consumption and reducing costs. CONSTITUTION: A non-power switching circuit(30) controls the supply of a general power which is applied to a power conversion circuit(40) from an SMPS(Switched Mode Power Supply)(10). If the supply of the general power is abnormally interrupted, the non-power switching circuit blocks the reverse current. A power-stop detecting module applies a recognition signal to a printer control module. A USB(Universal Serial Bus) current control module(50) applies USB power to a logic power control module(60).
