a) Data Input and Print Timing

8.3.4 Data Receiving Control

Your printer is able to receive data sent from the host side when the BUSY signal is LOW, but unable to
receive when the BUSY signal is HIGH.

8.3.5 Buffering

1) N Type
Your printer is provided with a two line input buffer.
2) B Type
Your printer is provided with a 7Kbyte input buffer. This makes possible a large amount of data buffering,
and therefore, the host side is free immediately after data transmission.
