GS r n
n = 1, 49 : Paper sensor status
[Function] Sends Status
[Code] ASCII GS r n
Hexadecimal 1D 72 n
Decimal 29 114 n
[Range] 1 n 2, 49 n 50
[Outline] This command sends the status, depending on setting of n.
[Caution] • The following tables describe the status sent.
• If DTR/DSR control is selected and the memory switch 4-5 is set to 0, the printer sends only 1
byte after confirming that the host is ready to receive (the DSR signal status is Space).
If the host is not ready (the DSR signal status is Mark), the printer will wait until it will be ready
to receive. If XON/XOFF control is selected or the memory switch 4-5 is set to 1, the printer
will send 1 byte without confirming the DSR signal status.
• Since this command is executed at deployment of the reception buffer, there may be a delay
between command reception and status sending, depending on the reception buffer
condition.
• If ASB is enabled by GS a, it is necessary to distinguish the status by this command from that
of ASB. See “6. Interface” for how to distinguish them.
• If n goes beyond the range, this command will be ignored.
