Transmit Status
Hexadecimal
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. This is found in the Real Time Commands section of this document.
