1 £ n £ 3, 49 £ n £ 51
[Range]
[Description] Transmits the status specified by n as, follows:
1, 49
2, 50
3, 51
· When DTR/DSR control is selected, the printer transmits only 1 byte after confirming
[Notes]
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, the printer transmits only 1 byte without
confirming the condition of the DSR signal.
· Since this command is executed when the data is buffered, there may be a time lag
between command reception and status transmission, depending on the receive buffer
status.
· When Automatic Status Back (ASB) is enabled using GS a, the status transmitted by
GS r and the ASB status must be differentiated using the table in Appendix B, Transmit
Status Identification .
· If the value of n is out of the specified range, the printer ignores this command.
· The status types to be transmitted are shown below:
n = 1: Paper sensor status
