[Notes] · When DTR/DSR control is selected in the serial interface model, the printer
transmits only 1 byte after confirming that the host is ready to receive data
(DSR signal is SPACE). If the host computer is not ready to receive data (DSR
signal is MARK), the printer waits until the host is ready.
· When XON/XOFF control is selected in the serial interface model, the printer
transmits only 1 byte without confirming the condition of the DSR signal.
· The printer ID is transmitted when the data in the receive buffer is developed.
Therefore, there may be a time lag between receiving this command and
transmitting the status, depending on the receive buffer status.
· When the printer ID transmission is specified with (1 £
n
£ 3) or (49 £
n
£ 51),
one byte code is transmitted.
· When Auto Status Back (ASB) is enabled using
GS a
, the status transmitted by
GS
I and the ASB status must be differentiated.
· When the printer ID transmission is specified with (65 £
n
£ 69), the following
contents are transmitted:
Header: Hexadecimal = 5FH / Decimal = 95 (1 byte)
Data: Printer information
NUL: Hexadecimal = 00H / Decimal = 0 (1 byte)
After the data is ready to be transmitted, the printer executes the following
process.
À Executes READY to BUSY. If it is already BUSY, the printer executes
nothing.
Á Transmits [Header + Data + NUL].
 Executes BUSY to READY. If it is already BUSY from any other cause, the
printer executes nothing.
