❑The column heading “Direction” refers to the direction of signal flow as
viewed from the printe r.
❑“Return” denotes the twisted -p air return to be connected at signa l ground
level. For the interfac e wiring, be sure to use a twisted-pair cable fo r each
signal and to complete the connec tion on the return side.
❑All interface conditions are based on TTL level. Both the rise and fall times of
each signal must be less than 0.2 microseconds.
❑Data transfer must be carr ied 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.
