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.
-
To receive the identification result correctly, 67 bytes or more space is required in the receive
buffer.
-
See 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
transmission. 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.
