CL-E700 series
2-4-4. Parallel Interface (Option)
(1)
Specifications
Transmission system 8-bit parallel data
Receive buffer size
16K bytes
Transmission modes
Compatible mode
It is an asynchronous forward channel mode to send the byte width
data from the host to the printer. The interface line of the data is
operated in accordance with signal line definitions of Centronics.
NIBBLE mode
It is an asynchronous reverse channel mode to send the data from
the printer to the host. In Nibble mode, 4-bit data (half byte) is sent at
a time using the 4 status lines (FAULT, SELECT, PE, and BUSY). To
send one complete byte data, the printer sends 2 nibbles (8 bits in
total) to the host. Nibble mode is usually combined with Compatible
mode to create a complete bi-directional channel.
ECP mode
ECP mode permits bi-directional asynchronous data transmission,
and by means of interlock handshake, it does not require the timing
necessary with Compatible mode.
Signal level
IEEE1284 compatible
