[Name] Transmit status

Hex
Decimal
[Range] n = 1, 2, 49, 50
[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
· When using a serial interface
[Notes]
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):
Bit Off/On Hex
0, 1 Off 00
On 03
2, 3 Off 00
On (0C)
4 Off 00
5, 6 - -
7 Off 00
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.
