NOTES: 1. For interface wiring, be sure to use a twisted-pair cable for each

side and connect the return side to the signal GND level.

To prevent noise, these cables should be shielded and con

nected to the chassis of the host computer.

2. Ail of the interface conditions are based on TTL levels.

The rising time and falling time of any signal should be 0.2 µs or

less.

3. Never transmit data without checking ACKNLG and BUSY.

(Data should only be transmitted to this printer after confirming that

ACKNLG is active, or when BUSY is "LOW".)

4. The interface cable should be as short as possible.
