Transmits paper sensor status
[Note]
λ
When using a serial interface
1) 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.
2) When XON/XOFF control is selected, the printer transmits only 1 byte
without confirming the condition of the DSR signal.
λ
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.
λ

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 status types to be transmitted are shown below:

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