3-5-3(b) Reverse Mode Specification (Nibble / Byte mode)
Data transmission from the printer to the host computer.
The STATUS data transmission from the printer to the host computer is accomplished in the Nibble or Byte
mode. This mode allows data transmission from the asynchronous printer under the control of the host
computer. Data transmission in the Nibble mode are made via the existing control lines in units of for bits
(Nibble). In the Byte mode, data transmission in accomplished by making the 8-bit data lines bidirectional.
Neither mode can operate at the same time as the compatibility mode, so switching is always required.
3-5-3(c) Signal Specification (Compatibility/Nibble/Byte mode)
