Transmit Status
Transmits the status specified by n.
This command is a batch mode command; that is, 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.

Notes
When DTR/DSR RS232C 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 RS232C communications handshaking control is selected, the printer
transmits the one byte response regardless of the host signal DSR.
When Auto Status Back (ASB) is enabled using the Enable/Disable Automatic Status Back
command (1D 61), the status transmitted by this command (Transmit Status) and the ASB
status must be differentiated according to the information found in “Recognizing Data
from the Printer,” (in the “Real Time Commands” section later in this chapter).
The status bytes to be transmitted are described in the following two tables.
