[Details]

When using a serial interface

 

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:

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.
