2) Buffer full state
Buffer full state is when the remaining capacity of input buffer is as shown below.
Table Input Buffer Full
Set Value Buffer Full Clear
4K bytes Remaining 128 bytes Remaining 256 bytes
45 bytes Remaining 16 bytes Remaining 26 bytes
・When the remaining capacity of input buffer is 0 byte, data received is read and
discarded.
3) Data receive error
When any of the following error occurs, data is printed as “?” or read and discarded
(Msw1-4).
・Parity error
・Framing error
・Overrun error
Note: When a command accompanying flash ROM write is used, the printer may
become BUSY (DTR) temporarily at write operation. In this case, as the printer
cannot process anything, the transmitted data may possibly be discarded.
