2) Handshake : Simplified procedure
Protocol:
When receiving program data, the printer checks the checksum. If no
error is found, the printer returns ACK. If any error is found, the
printer returns NAK.
error is found, the printer returns ACK. If any error is found, the
printer returns NAK.
If the host computer resends the data in spite of the printer returning
ACK, the printer ignores the data and returns ACK again.

(Whether to resend the data be not is judged based on the sequence
NO. in the program data packet.)
