[Description] • Transmits the key code list identifying the stored record.
Hexadecimal Decimal Amount of data
Header 37H 55 1 byte
Identifier 71H 113 1 byte
Status 40H or 41H 64 or 65 1 byte
Data 20H – FEH 32 – 254 2 – 80 bytes
NUL 00H 0 1 byte
•
Data consists of the data groups identified with key codes.
• If the specified record cannot be detected, the contents of the transmitted data are as follows:
Hexadecimal Decimal Amount of data
Header 37H 55 1 byte
Identifier 71H 113 1 byte
Status 40H 64 1 byte
NUL 00H 0 1 byte
• After the [Header – NUL] is transmitted, the printer receives a response from the host; then it
performs the process defined by the response. (See the tables below.)
When the status (existence of the next data block) is
Hexadecimal = 41H / Decimal = 65,
Response
ASCII Decimal
Process performed
ACK 6 Transmits the next data
NAK 21 Transmits the previous data again
CAN 24 Ends the process
When the status (for the last data block) is
Hexadecimal = 40H / Decimal = 64,
Response
ASCII Decimal
Process performed
ACK 6 Ends the process
NAK 21 Transmits the previous data again
CAN 24 Cancels the process
