EFP9800 ESC/POS Commands
6–54 3255 4073–002
Transmit Status
Transmits the status specified by the value of n.
In RS-232C communications, when DTR/DSR control is selected, the printer
confirms that the host computer is ready to receive data (DSR signal is SPACE)
and then transmits only one byte. If the host computer is not ready to receive
data (DSR signal is MARK), the printer waits until the host computer is ready.
When XON/XOFF control is selected, the printer transmits only 1 byte before
checking the DSR signal.
Because status is transmitted when this command is buffered, there may be a
lag between command reception and status transmission, depending on the
receive buffer state.
Note: When the Enable/Disable Automatic Status Back (ASB) command (1D
61) is enabled, the status transmitted by ASB and by this command
must be distinguished.
Paper sensor status and slip status may not be accurate for paper with holes.
