FS b

[Name] Request retransmission of check paper reading result
[Format] ASCII
Hex
Decimal
[Description] Retransmits the previous check paper (MICR character) reading reaults.
· Since this command is executed after being buffered in the receive buffer, there may
[Notes]
be a time lag between sending this command and starting MICR reading.
· When the previous MICR reading results are correct, the printer transmits header +
reading status + identified character strings + NUL to the host computer. If it is
abnormal, or when FS a 0 is not executed, the printer transmits header + reading status
+ NUL to the host.
· When DTR/DSR control is selected, the printer transmits all data consecutively after
confirming whether the host computer is ready to receive data . When the host is not
ready to receive data, the printer waits until the host is ready.
· When XON/XOFF control is selected, the printer transmits all data consecutively
without confirming whether the host computer is ready to receive data. The data
transmission must be consecutive, except for the XOFF code.
· The printer transmits all data collectively without confirming whether the host computer
is ready to receive data after transmitting header. To receive identification result
correctly, 67 bytes or more space is required in the receive buffer.
· Refer to the FS a 0 command description for header, reading status, and identified
character strings.
· During identification result transmission, the printer ignores DLE EOT n , DLE EOT BS
n , and GS ENQ. Also, the printer does not transmit ASB during reading and
identification result tranmission. Therefore, the user cannot confirm changes in the
printer status during these periods.
· It is possible to differentiate the reading results of MICR, ASB, and real-time status.
Refer to Appendix B for data identifying method.
