A-2 FS-6700
A.1 Parallel interface
The printer uses a bi-directional parallel interface for high-speed data transmis-
sion for the host computer. This interface includes the buffers which are compatible
with the IEEE 1284 standards. The parallel interface provides support for the ECP
and nibble modes in this standard.
Port pin assignment
The pins of the parallel interface connector carry the signals listed below.
Parallel interface connection
Detailed descriptions of the parallel interface signals follow.

Signal Pin Meaning
Strobe* [nStrobe] 1 A negative-going Strobe* pulse causes the printer to read
and latch the data on the Data 0 [1] to Data 7 [8] signal
lines.
Data 0 [1] to Data 7 [8] 2-9 These eight signals form the data byte sent from the host
computer to the printer. Data 7 [8] is the most significant
bit.
