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.
