Transmit Status
Transmits the status specified by n. This is a batch mode command which transmits the
response 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 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 in this
document).
