[Details] • 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 Automatic Status Back (ASB) is enabled by command
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):

1 0 00 0 Paper roll near-end sensor: paper
adequate.
1 03 3 Paper roll near-end sensor: paper near
end.
