Notes to the Parallel Pinouts Table
n
Direction refers to the direction of signal flow as viewed from the
printer.
n
Return denotes “twisted-pair return” and is to be connected at
signal-ground level. When wiring the interface, be sure to use a
twisted-pair cable for each signal and never fail to complete connection on the return side. To prevent noise effectively, these
cables should be shielded and connected to the chassis of the
system unit and printer, respectively.
n
All interface conditions are based on Transistor-Transistor Logic
(TTL) level. Both the rise and fall times of each signal must be
less than 0.2 microseconds.
n
Data transfer must be carried out by recognizing the ACKNLG or
BUSY signal.
