EFP9800 ESC/POS Commands

•The printer transmits only one byte after confirming that the host computer is ready when DTR/DSR protocol is selected. One byte is transmitted without confirming the signal when XON/XOFF protocol is selected.

•When the command is buffered, a status is sent causing a possible delay between when the command is received by the host computer and the status sent. This is dependent on the state of the receive buffer.

•When the Enable/Disable Automatic Status Back command (1D 61) is used to enable Auto Status Back, the status transmitted by this command (Transmit Printer ID) and the Auto Status Back must be differentiated.

•The ROM version may depend on releases of the product.

•The command is ignored if n is out of the specified range.
