Reverse communication (Printer Host): Nibble or Byte Mode
Reverse Mode (Data Transmission from Printer to Host)
The STATUS data transmission from the printer to the host is proceeded in the Nibble or Byte
mode.
This mode allows data transmission from the asynchronous printer under the control of the
host.
Data transmissions in the Nibble Mode are made via the existing control lines in unists of four
bits (Nibble). In the Byte Mod e, data transmissions are proceeded by making the eight-bit data
lines bidirectional.

The both modes fail to be proceeded concurrently with the Compa tibility Mode, ther eby causing
half duplex transmission.
The IEEE 1284 Nibble/Byte Modes are under development in the form of draft and may be
subject to change.
