abnormal emergency, as the follo ing form sho s:
When the assemblies of printer appear the foresaid errors, parallel interface
／ERR pin became “0”signal level, and automatically send one byte
ERROR code through TXD parallel interface, the status of printer can be
transmitted by ESC v command.
Red PAPEROUT light is paper end indicator. When there is no paper in the
print head, the indicator flashes, and sends one byte 84H code through
TXD serial interface, hile it goes dark in normal status.
