TECHNICAL MANUAL
[Description]
Transmits the status specified by n as follows:
N
Function
1,49
Transmits paper sensor status
2,50
Transmits drawer kick-out connector status
[Notes]
When using a serial interface
When DTR/DSR control is selected, the printer transmits only 1 byte after
confirming 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.
This command is executed when the data in the receive buffer is
developed.
Therefore, there may be a time lag between receiving this command and
transmitting the status, depending on the receive buffer status.
When Auto 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 G.
The status types to be transmitted are shown below:
Paper sensor status ( n = 1, 49):

Bits 2 and 3:
When the paper end sensor detects a paper end, the printer goes off-line
and does not execute this command. Therefore, bits 2 and 3 do not
transmit the status of paper end.
