Note:
1. The column heading "Direction" refers
signal flow as viewed from the printer.
2. "Return" denotes the twisted-pair return, to be connected at
signal ground level. For the interface wiring, be sure to use a
twisted-pair cable for each signal and to complete the
connection on the return side.
3. All interface conditions are based on TTL level. Both the rise
and the fall times of each signal must be less than 0.2
microseconds.
4. Data transfer must be carried out by observing the ACKNLG
or BUSY signal. (Data transfer to this printer can be carried
out only after receipt of the ACKNLG signal or when the
level of the BUSY signal is LOW.)
