[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) |
➀Executes READY to BUSY. If it is already BUSY, the printer executes nothing.
➁ Transmits [Header + Data + NUL].
➂Executes BUSY to READY. If it is already BUSY from any other cause, the printer executes nothing.
