ESC v （At Serial I/F Selection）
[Function] Sending printer status
[Code]
<1B>H<76>H
[Outline] Sends the current status of the printer.
[Caution] • The status to be sent is one byte and the content is shown in the following table.
• With DTR/DSR control, after confirming that the host is ready for reception (DSR
signal is space), only one byte is transmitted. With XON/XOFF control, only one byte is
transmitted without confirmation of DSR signal state.
• With DTR/DSR, when the host is not ready for reception (DSR signal is mark state),
this command waits till reception is ready.
• As the printer is Busy in the Paper-end state, this command may be in the state not
ready for reception.
• This command is valid only for serial interface.
