6.4 RESPONSE DATA

All of upper 4 bits in response data sent from the printer to the host device are identifiers. Table 6-7 shows
the meanings to the identifiers.
Identifier
2xH to 7xH
The responses are sent in the following forms.
(1) Character string
The data is sent in the order of start code (02H), character string, and termination code (00H).
For example, when the character string 'SII' is sent from the printer:
02H, 53H, 49H, 49H, 00H
(2) HEX code
The data is sent in the order of start code (0EH), lower byte of HEX code, higher byte of HEX code, and
termination code (00H).
For example, when 12H, 34H, and 56H are sent from the printer:
0EH, E2H, F1H, E4H, F3H, E6H, F5H, 00H
(3) Execution response
One byte data which is the logical sum of lower 4 bits of the parameter n input in the "Execution
Response Request" command (DC2 'q') and 80H is sent.
For example, when inputting n = 4:
84H
(4) Status response, realtime status response
The status byte specified by the "Send Status Data" command (GS 'r') or "Send Status Data in Real
Time" command (DLE EOT) is sent in 1 byte.
Do not transmit the next data until the corresponding status is received after executing "Send Status
Data in Real Time" command (DLE EOT).
In addition, do not send "Send Status Data in Real Time" command (DLE EOT) until all response data
is retrieved when the response command other than "Send Status Data in Real Time" command (DLE
EOT) is executed.
