PROGRAM DATA

PRINTER

ACK

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.

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.)

The time-out period is 10 seconds.
