When DTR/DSR RS232 communications handshaking control is selected, the printer
transmits the one byte response only when the host signal DSR indicates it is ready to
receive data.
When XON/XOFF RS232 communications handshaking control is selected, the printer
transmits the one byte response regardless of the host signal DSR.
This command is a batch mode command; the response is transmitted after all prior data in
the receive buffer has been processed. There may be a time lag between the printer
receiving this command and transmitting the response, depending on the receive buffer
status.
When Auto Status Back (ASB) is enabled using GS a n, the status transmitted by GS I n
and the ASB status must be differentiated using the information titled “recognizing data
from the printer” in this appendix, section 9.8.22 Real Time Commands.
When n is out of the specified range, this command is ignored.
