NOTES: • When a signal that does not satisfy the requirements above is input, printer operation is not

guaranteed. When a signal is input to pin 25 (INIT) at the TTL level, the requirements above

must also be satisfied. Although a signal is input to pin 6 (DSR) at the TTL level, according to

the DC characteristics described above, the operation is not guaranteed and pin 6 cannot be

controlled.

• When pin 6 (DSR) and pin 25 (INIT) are open, the printer is operating.
