6.4 MICR Control Commands (when the printer is used with the MICR reader)

DLE EOT BS n

[Name] Real-time MICR status transmission
[Format] ASCII
Hex
Decimal
[Range] n = 1
[Description] Transmits the selected MICR status specified by n in real time as follows:
n
1
· The status information to be transmitted is shown in the tables on the following pages.
[Notes]
· The printer starts MICR status transmission when this command is buffered in the
receive buffer.
· When transmitting status, the printer transmits only 1 byte without confirming the
condition of the DSR signal.
· This command is executed even when the printer is off-line, the receive buffer is full,
or an error occurs.
· The status is transmitted whenever the data sequence for DLE EOT BS n ( n = 1) is
received.
Example:
In ESC * * * * m n
d4 = 01H (1)
· This command should not be contained within another command that consists of 2 or
more bytes.
Example:
If you attempt to transmit ESC 3 n to the printer, and then DLE EOT BS 1 interrupts
before n is received, the code 10H (16) for DLE EOT BS 1 is processed as the code
for ESC 3 10H (16).
· This command is unavailable when using ESC = (select peripheral device) to select the
printer to be disabled.
· This command is unavailable during MICR reading result transmission (FS a 0, and
FS b).
· When Automatic Status Back (ASB) is enabled using the GS a command, the status
transmitted by the DLE EOT BS command and the ASB status must be differentiated
using the table in Appendix B, Transmit Status Identification .
· If the value of n is out of the specified range, the printer ignores this command.
