[Details]

When DTR/DSR control is selected in the serial interface model, the printer transmits the

 

 

printer ID 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 the

 

 

printer ID 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 printer ID transmitted by GS I and

 

 

the ASB status must be differentiated using the table in Appendix G.

 

After the data is ready to be transmitted, the printer executes the following process.

 

When the printer ID transmission is specified with (65 n 68), the following contents are

 

 

transmitted:

 

 

Header: Hexadecimal = 5FH / Decimal = 95 (1 byte)

 

 

Data:

Printer information

 

 

NUL:

Hexadecimal = 00H / Decimal = 0 (1 byte)

Executes READY to BUSY. If it is already BUSY, the printer executes nothing.

Transmits [Header + Data + NUL].

Executes BUSY to READY. If it is already BUSY from any other cause, the printer executes nothing.
