GS r n

[Function]

Sending status

[Code]

<1D>H<72>H

[Range]

[Outline]

Sends the specified status to the host.

n = 1, 49: Sends the Paper Sensor status.

n = 2, 50: Sends the Drawer Kick-Out Connector status.

[Caution]

• When the serial interface is used:

For DTR/DSR control:

The printer sends the status after verifying that the host is
ready to receive. If the host is not ready to receive, the
printer waits for the host to become ready to receive.

For XON/XOFF control:

The printer sends the status without checking whether the
host is ready to receive or busy.

• Because this command is executed when data is mapped in

the receive buffer, there may be a delay between receiving the
command and sending the status depending on the condition
of the receive buffer.

• If ASB (Automatic Status Back) is enabled by GS a, the host

must discriminate between the status due to this command
and the status due to ASB.

• Paper Sensor status (n = 1, 49)

Bits 2, 3: Whenever the Paper end Sensor detects a “paper out”

state, the printer goes offline, and the command is
not executed. The printer, therefore, never sends a
status where bit 2 = “1” or bit 3 = “1”.
