8 External signal interface
8.1 Basic Specifications
External interfaces are designed to be able to connect with the printer and the other peripherals.
The external interface operates only in the pulse input mode (a mode that operate according to external signals).
However, error signals are outputted with the all mode.
Setting related to the external signals can be done on the extended setting mode at the printer.
